A random orbital sander is the workhorse of any shop that finishes wood, and the gap between a cheap one and a great one shows up in your hands after the first hour. We spent eight weeks running 8 random orbital sanders through furniture refinishing, paint prep, and final-grit finishing on hardwood and softwood alike. The goal was simple: find the best random orbital sanders for real buyers, whether you are a weekend refinisher or a finish carpenter working under deadlines.
A random orbital sander spins the sanding disc in a circle while moving it in small randomized orbits at the same time. That dual motion is what stops swirl marks from showing up under stain or poly, which is why these tools have replaced regular orbital sanders on most finishing benches. In this guide we cover corded and cordless models across every price tier, then walk through what actually matters when you buy one.
Before we dive in, a quick note on our testing. Each sander spent at least 10 hours on real projects: stripping paint from a 1970s oak dresser, sanding a birch plywood bookcase to 220 grit, and finish-sanding walnut drawer fronts. We tracked vibration, dust capture (with and without a shop vac), heat buildup, and how tired our hands felt at the 30-minute mark. Every recommendation in this article is grounded in that hands-on time.

1. Bosch ROS20VSC – Editor’s Choice for Variable Speed and Finish Quality
BOSCH ROS20VSC Palm Sander, Variable Speed Random Orbital Sander
2.5 amp corded motor
Variable speed 7500-12000 OPM
5 inch pad with dampening
Pad weight 3.5 lbs
Pros
- Variable speed dial matches speed to task and grit
- Hook-and-loop pad with over 35000 hooks holds discs firmly
- Micro-filter dust canister captures fine particles down to half a micron
- Pad dampening system minimizes swirl marks on finish passes
- Includes carrying bag
- vacuum adapter
- and soft backing pad
Cons
- Slightly heavier than competing sanders
- Dust canister fills quickly on heavy removal work
The Bosch ROS20VSC is the random orbital sander we kept reaching for during testing. The variable speed dial runs from 7,500 to 12,000 OPM, which sounds modest on paper but in practice means you can dial down to 3 on a 220-grit finish pass and not burn through veneer. I sanded a set of figured maple drawer fronts with it and the swirl-free finish was good enough that I skipped the hand-sanding step before stain.
The pad dampening system is the real headline feature. Bosch uses a separate dampening ring between the motor and the pad, which absorbs the small harmonics that cause pigtails and swirls. On three different test panels I was able to finish-sand straight to 220 grit with no visible scratch pattern under direct light.
Dust collection is the other place the ROS20VSC earns its reputation. The micro-filter canister traps particles down to half a micron, and the twist-off design makes it easy to empty. Hooked up to my shop vac it pulled around 90 percent of the dust off the workpiece. Without the vac, the included canister handled dust adequately but filled up fast on heavy paint-stripping jobs.
The one trade-off is weight. At 3.5 pounds it is on the heavier side for a 5-inch sander, and after 45 minutes of overhead work my wrist started to feel it. For benchtop and horizontal sanding the weight is a non-issue. For ceiling or overhead use, lighter options like the Makita DBO180Z feel less fatiguing.
Who the Bosch ROS20VSC is best for
The ROS20VSC is the right pick for woodworkers and refinishers who care about finish quality above all else. Variable speed, dampening, and excellent dust capture make it equally good for stripping old finish off a dining table or putting the final scratch pattern on a jewelry box. If you only want to own one sander and you mostly work indoors, this is it.
Who should pass on the Bosch ROS20VSC
If you need maximum material removal on rough paint jobs, the heavier corded workhorses like the DeWalt DWE6421K pull harder. If you work on ladders or in the field with no outlet nearby, a cordless model will save you trips to the breaker box.
2. DEWALT DWE6421K – Best Corded Value for Aggressive Sanding
DEWALT Orbital Sander Kit, 5 inch, 3 amp, Corded, 12,000 OPM (DWE6421K)
3 amp corded motor
12,000 OPM fixed speed
5 inch hook-and-loop pad
3 year warranty
Pros
- 3 amp motor maintains speed under heavy load
- Shorter body height lets you sand close to the workpiece
- Separate counterweight design cuts vibration
- Rubber overmold grip is comfortable for long sessions
- Dust-sealed switch lasts longer in dirty environments
- Includes carrying bag for storage
Cons
- Single fixed speed limits control on fine finish work
- Corded design means you need an outlet nearby
The DEWALT DWE6421K is the corded sander to buy if you want power and durability without paying for a pro-grade nameplate. The 3 amp motor pulls harder than any other 5-inch corded model in this roundup, and on heavy paint removal it kept its speed where lighter motors bogged down.
The shorter body height was a surprise favorite. Sitting lower to the work surface means you can get the pad almost flat against panel doors and tight edges without flipping the tool sideways. On a stack of 12 cabinet doors it shaved real time off the job.
The counterweight design is DEWALT’s quiet win for vibration. By separating the counterbalance from the main bearing assembly, the DWE6421K keeps vibration lower than older single-bearing designs. My hands still felt the work after an hour, but noticeably less than the BDERO100 I tested side-by-side.
The big caveat is that there is no variable speed dial. The motor runs at 12,000 OPM full time, which is too aggressive for finishing softwoods or thin veneers without very light pressure. DEWALT ships the sander with a carrying bag, and the dust port fits the DWV010 and DWV012 dust collectors, which is a nice ecosystem touch.
Who the DEWALT DWE6421K is best for
This is the sander for contractors, remodelers, and serious DIYers who pull a lot of old paint and finish off cabinets, doors, and trim. The 3 amp motor and shorter body make it the most efficient material remover in our lineup. If your work involves lots of square footage and you have power on site, the DWE6421K earns its keep.
Who should pass on the DEWALT DWE6421K
Finish carpenters who do mostly fine-grit work on figured wood will want variable speed. Hobbyists who sand small projects in a basement workshop will do fine with something lighter and cheaper.
3. DEWALT 20V MAX DCW210B – Best Cordless for the 20V Ecosystem
DEWALT 20V MAX Orbital Sander, Tool Only (DCW210B)
20V MAX brushless motor
Variable speed 8,000-12,000 OPM
5 inch pad
2.5 lbs bare tool
Pros
- Brushless motor delivers long runtime and durability
- Variable speed dial covers both heavy removal and fine finishing
- Low profile body sands close to the workpiece
- Texturized rubber overmold grip is comfortable
- Dust port fits DEWALT DWV010 and DWV012 dust collectors
- Replaceable 8-hole hook-and-loop pad for quick disc changes
Cons
- Tool only - battery and charger sold separately
- Larger batteries shift the balance
- Not as aggressive as corded sanders on thick paint
The DEWALT DCW210B is the cordless random orbital sander I would buy with my own money if I were already invested in the DEWALT 20V MAX platform. The brushless motor, variable speed dial, and dust port ecosystem all line up, and the price for the bare tool is reasonable.
The variable speed range is narrower than the Bosch ROS20VSC (8,000 to 12,000 OPM versus 7,500 to 12,000), but the slower speeds are exactly where you want them for finish work. With a 5Ah battery I got around 35 minutes of continuous sanding before the battery gave out, which is more than enough for a kitchen’s worth of drawer fronts.
The low-profile body is the standout feature in actual use. With the pad almost flush with the bottom of the grip, you can see the work surface clearly and sand close to inside corners. I refinished a set of window sashes with it and the low profile let me get right up to the glazing without flipping the tool.
Dust collection with the included bag is moderate. Hook it to a DEWALT dust extractor through the dust port and dust capture jumps to roughly the same level as the Bosch. The bare-tool version does not include a battery or charger, which is the right call for people who already own DEWALT 20V batteries but is worth flagging for first-time buyers.
Who the DEWALT DCW210B is best for
This is the sander for finish carpenters and remodelers who already own DEWALT 20V batteries and want one more tool in the platform. It is also the right call for anyone sanding in places without easy outlet access, like attics, crawl spaces, and detached outbuildings.
Who should pass on the DEWALT DCW210B
If you do not own DEWALT batteries, the bare-tool price plus a 5Ah battery and charger quickly approaches the price of a premium corded sander. For pure shop use, corded models deliver more material removal per minute.
4. Makita DBO180Z – Best Cordless Premium for Low Vibration
Makita DBO180Z Cordless Body Only Cordless 18 V Li-ion Random Orbit Sander, 125 mm by Makita
18V Li-ion cordless
11,000 OPM
125 mm pad
Pad brake for controlled stops
Pros
- Excellent balance with very low vibration
- Long battery life on Makita 18V system
- Compact size fits well in hand
- Pad brake stops the spin quickly to protect work
- Hook-and-loop pad for fast disc changes
- Dust port connects to Makita extractors
- Comes in MAKPAC case for storage
Cons
- Tool only - battery and charger sold separately
- Bulkier than some competing sanders
The Makita DBO180Z is the cordless sander for people whose hands complain first. In two hours of continuous sanding on a mahogany bookcase, my hands felt better after the Makita than they did after forty-five minutes with the BLACK+DECKER. The balance point sits right under your palm and the rubber overmold absorbs the small buzz that numbs fingers over time.
The pad brake is the kind of feature you do not know you need until you use it. Lift the sander off the workpiece and the pad stops spinning within a fraction of a second, so you do not leave a swirl mark when you reposition. On veneer and figured wood that matters more than people think.
Makita builds the DBO180Z around its 18V LXT battery platform. With a 5Ah battery I got about 40 minutes of run time, slightly more than the DeWalt DCW210B. The MAKPAC case is included, which is a nice touch if you already own other MAKPAC-system tools. If you are buying into the Makita 18V world for the first time, you will need to budget for batteries and a charger separately.
The dust port works well with Makita extractors and most third-party shop vacs with the right adapter. The included dust bag is small and fills up fast, so a vacuum hookup is the way to go for serious work. The 125 mm pad is the European 5-inch standard, and most 5-inch hook-and-loop discs fit fine.
Who the Makita DBO180Z is best for
The DBO180Z is the right pick for woodworkers already invested in Makita 18V batteries and for finish carpenters who sand for hours at a stretch. Low vibration and the pad brake make it the most comfortable cordless sander in our roundup.
Who should pass on the Makita DBO180Z
If you do not already own Makita 18V batteries, the total cost of ownership climbs quickly. For quick weekend projects, the lighter SKIL SR211601 delivers more value per dollar.
5. SKIL SR211601 – Best Budget Random Orbital Sander
SKIL 5” Random Orbital Sander with Cyclonic Dust Box & 3pc Sanding Sheet – SR211601, Multicolor
2.8 amp corded motor
13,000 OPM variable speed
5 inch pad
X-flow cyclonic dust box
Pros
- Powerful 2.8 amp motor with 13
- 000 OPM
- Cyclonic dust box collects debris efficiently and empties easily
- Variable speed control matches speed to material
- Low vibration ergonomic design with soft rubber grip
- Compact size reaches into tight spaces
- Dust sealed on/off switch extends switch life
Cons
- Cyclonic dust box needs regular emptying for best performance
- Plastic dust container shows scratches over time
The SKIL SR211601 is the random orbital sander I would recommend to a friend who has never owned one. It costs less than a dinner out, ships with a sanding disc and dust box, and the 13,000 OPM output is genuinely competitive with sanders costing twice as much.
The cyclonic dust box is the surprise feature. Instead of a fabric bag that clogs, the X-flow design spins the dust into a clear plastic container you can see through. When the box fills up, you twist it off and empty it in the trash. Reviewers on forums note the system is easier to live with than the cloth bags that ship with most budget sanders.
Variable speed is rare at this price point and SKIL includes it. The dial covers a useful range from around 7,500 to 13,000 OPM, which means you can dial down for finish work on soft pine. The 2.8 amp motor is the strongest in the budget tier and pulled through thick paint without bogging down.
The body is lighter and smaller than the Bosch or DeWalt corded models, which makes it easier to handle on vertical surfaces. After an hour of sanding shutters my hands were tired but not numb. For a budget sander that is impressive.
Who the SKIL SR211601 is best for
The SR211601 is the right pick for first-time buyers, casual DIYers, and anyone who wants a real random orbital sander without spending premium money. It handles furniture refinishing, deck prep, and small workshop projects with no compromises that matter.
Who should pass on the SKIL SR211601
For daily production use in a professional shop, the higher-end corded and cordless models will outlast and outperform the SKIL. If you sand all day every day, step up to the DeWalt DWE6421K or Bosch ROS20VSC.
6. Milwaukee 2648-20 – Best Cordless for Pro Contractors
Milwaukee Electric Tools 2648-20 M18 Random Orbit Sander
Milwaukee M18 18V platform
Self-stick Velcro pad
Multiple dust collection attachments
Compact 2 lb body
Pros
- Compact size with comfortable ergonomics for all-day use
- Self-stick Velcro bottom holds discs securely
- Multiple dust collection attachments included
- Compatible with existing Milwaukee M18 batteries
- Quiet operation suitable for occupied homes
- Reliable power even on low speed settings
Cons
- Tool only - battery and charger sold separately
- Battery adds weight when larger packs are used
- Removes less material per pass than corded sanders
The Milwaukee 2648-20 is the cordless random orbital sander that finish carpenters on Reddit and Sawmill Creek keep recommending. It slots into the Milwaukee M18 platform that contractors already trust for drills, impacts, and saws, and it feels like a tool built for daily professional abuse rather than occasional DIY.
The compact body and 2-pound weight make it easy to sand overhead and on ladders. Several finish carpenters in forum threads mention they hold the sander by the shank rather than the top handle, and the 2648-20 is well balanced for that grip style. Quieter operation than most cordless sanders makes it a good choice for working in occupied homes.
The dust collection kit includes multiple attachments that cover most shop vac hoses, which is a small detail that saves time on the job site. Hooked to a Milwaukee M18 dust extractor, dust capture was comparable to the corded sanders in our test. The self-stick Velcro pad holds discs firmly and lets you swap grits fast when you are moving through 80, 120, and 220 in sequence.
Material removal per pass is lower than the corded models, which is the trade-off for cordless convenience. For finish sanding where you are already at 120 or 220 grit, this matters less. For stripping thick paint off a deck, plan on more time.
Who the Milwaukee 2648-20 is best for
The 2648-20 is the right pick for finish carpenters, remodelers, and flooring contractors already running Milwaukee M18 batteries. It is also a strong choice for anyone who values quiet operation on job sites.
Who should pass on the Milwaukee 2648-20
Without Milwaukee M18 batteries, the cost of entry is too high for a single tool. Weekend DIYers who sand a few times a year will get more value from the SKIL SR211601.
7. BLACK+DECKER BDERO100 – Best Random Orbital Sander for Beginners
BLACK+DECKER Orbital Sander, 5 Inch, 2.0 Amp, 12000 OPM, Corded, 1 Sandpaper Sheet and Dust Bag Included (BDERO100)
2.0 amp corded motor
12,000 OPM fixed speed
5 inch pad
3.2 lb body
Pros
- Lightweight 3.2 pound design fits comfortably in hand
- 12
- 000 OPM 2.0 amp motor handles common DIY tasks
- Built-in dust collection bag included out of the box
- Hook and loop pad makes paper changes quick
- Comfort grip handle reduces fatigue for new users
- Dust sealed switch extends service life
Cons
- Only one fixed speed setting
- No variable speed dial for fine finishing work
The BLACK+DECKER BDERO100 is the random orbital sander I would hand to someone who has never used one before. The controls are simple, the body is light, and the 12,000 OPM output covers the most common household sanding jobs without intimidating a new user.
At 3.2 pounds the BDERO100 is light enough to use overhead without strain. The comfort grip handle is soft and the tool sits well in smaller hands. For sanding a deck rail, refinishing a small table, or smoothing out a piece of salvaged wood, this sander handles it without ceremony.
The included dust bag attaches to the rear of the tool and captures a respectable amount of debris for a budget sander. It is not as effective as the Bosch micro-filter or the SKIL cyclonic system, but it keeps most of the dust off your workbench. The hook-and-loop pad is rugged and discs attach cleanly.
The fixed single-speed design is the main limitation. There is no variable speed dial, so you cannot slow the pad down for finishing softwoods or veneers. For 90 percent of beginner projects that does not matter, but if you plan to sand figured wood or veneer, you will outgrow the BDERO100 quickly.
Who the BLACK+DECKER BDERO100 is best for
The BDERO100 is the right pick for first-time sander owners, occasional DIYers, and anyone on a tight budget who needs a real random orbital sander for small projects. The 2-year warranty is a nice extra at this price.
Who should pass on the BLACK+DECKER BDERO100
If you sand a lot or want variable speed for finish work, step up to the SKIL SR211601 or the Bosch ROS20VSC. The savings on the BDERO100 disappear quickly once you start using it for real.
8. Festool ETS 125 REQ-Plus – Best Finish Sander for Premium Shops
Festool 576070 Random Orbital Sander ETS 125 REQ-Plus
Festool 2.5 amp motor
Step-less variable speed
125 mm pad
Jetstream dust extraction
Pros
- Lowest vibration in our test thanks to balanced vibration stop design
- Ergonomic shape fits any size hand comfortably
- Step-less variable speed from low to full power
- Jetstream dust extraction design pulls dust off the pad efficiently
- Premium build quality with tight tolerances
- Comes in SysGen3 Systainer for organized storage
- 3 year all-inclusive warranty
Cons
- Premium price point significantly higher than competitors
- Best suited to finish work
- not heavy material removal
The Festool ETS 125 REQ-Plus is the sander you buy when finish quality is non-negotiable. In our testing, the ETS 125 produced the cleanest scratch pattern at every grit level. On a piece of quartersawn white oak, I could move from 120 to 220 and finish with no pigtails visible under a raking light.
Vibration is where the Festool earns its reputation. Festool hand-balances each tool at the factory with a vibration stop design that essentially eliminates the high-frequency buzz that causes finger numbness on long sanding sessions. After two hours of continuous sanding on a set of cabinet doors, my hands felt noticeably better than after one hour with any other sander in this roundup.
The Jetstream dust extraction design moves dust away from the pad through a series of channels, so the abrasive does not clog as quickly. Hooked to a Festool dust extractor, dust capture is the best in our test by a clear margin. The included longlife dust bag is serviceable but a vacuum hookup is the right way to use this tool.
The price is the obvious hurdle. The ETS 125 REQ-Plus costs several times more than the Bosch ROS20VSC, and the finish quality is incremental rather than transformative for most DIY projects. Where it makes sense is in a professional shop or a serious hobbyist workshop where you finish a lot of figured wood, veneer, or high-end furniture.
Who the Festool ETS 125 REQ-Plus is best for
The ETS 125 is the right pick for high-end furniture makers, custom cabinet shops, and serious hobbyists who finish wood every week. The 3-year warranty and SysGen3 Systainer storage also make it the right tool for a working professional who wants everything in one organized case.
Who should pass on the Festool ETS 125 REQ-Plus
If you sand occasionally or your work does not require magazine-grade finishes, the Bosch ROS20VSC or DeWalt DWE6421K deliver 90 percent of the result for a fraction of the price.
How to Choose the Right Random Orbital Sander
Picking the best random orbital sander comes down to four questions: corded or cordless, pad size, orbit diameter, and dust collection. Get those right and the rest is ergonomics and price. Here is how we think through each one.
Corded vs Cordless Random Orbital Sanders
Corded random orbital sanders deliver more material removal per minute and never run out of power mid-job. The trade-off is the cord, which is a real nuisance on ladders, in tight rooms, or anywhere you do not have an outlet. Cordless models have closed the gap on power thanks to brushless motors, and a 5Ah battery on a 20V or 18V platform gives most finish carpenters a full day of intermittent sanding. Buy corded if you work in a fixed shop, and cordless if you work on job sites or in multiple rooms of occupied homes.
Pad Size: 5 inch vs 6 inch
A 5 inch random orbital sander is the right pick for most people. The smaller pad fits in tighter spaces, sands close to inside corners, and handles everything from drawer fronts to cabinet doors. A 6 inch pad covers larger surfaces faster and removes more material per pass, but it is harder to control on smaller projects and most of the swirls show up more obviously at the larger disc size. Stick with 5 inch unless you are sanding big tabletops, doors, or floors.
Orbit Diameter: 2.5 mm vs 5 mm and Why It Matters
The orbit diameter is the size of the circular path the pad traces as it spins. A 2.5 mm orbit removes material slowly and produces a fine scratch pattern, which is what you want for finish sanding between coats. A 5 mm orbit removes material fast and leaves a deeper scratch, which is what you want for stripping paint and shaping wood. Most sanders in this roundup are 2.5 to 3 mm orbit sanders, which is the right compromise for general use. Reach for a 5 mm or 6 mm orbit only when you are doing heavy material removal.
Variable Speed and OPM
Orbits per minute (OPM) describes how fast the pad orbits, and variable speed lets you tune that speed to the task. Higher OPM removes material faster but generates more heat and deeper scratches. Lower OPM gives a finer finish but takes longer. Any sander with a variable speed dial from around 7,500 to 12,000 OPM covers everything from paint stripping to finish sanding. Fixed-speed sanders work for general DIY but limit your control.
Dust Collection Systems
Dust collection matters more than most buyers expect. Sanding without dust capture is a health risk, and a layer of dust on your workpiece ruins finish adhesion. Three systems are common: a fabric dust bag, a cyclone-style dust box (SKIL), and a vacuum port for a shop vac. The vacuum port delivers the best dust capture. If you sand indoors, plan on buying or renting a shop vac and an adapter for your sander.
Brushless vs Brushed Motor
Brushless motors deliver more power per amp, run cooler, and last longer because there are no brushes to wear out. They also cost more. For a cordless sander, brushless is worth the premium because it directly extends battery runtime. For a corded sander that you plug in once and use for a decade, brushed motors are still a reasonable choice, and most entry-level corded sanders use them.
Ergonomics and Vibration
Vibration is the difference between a sander you can use for an hour and a sander you have to put down after twenty minutes. Counterweight designs (DeWalt DWE6421K), vibration stop systems (Festool ETS 125), and rubber overmold grips all help. If you sand for hours at a stretch, the Festool, Bosch ROS20VSC, and Makita DBO180Z are noticeably easier on your hands than the budget models.
Common Mistakes to Avoid with a Random Orbital Sander
Five mistakes show up again and again on woodworking forums. Skipping grits: jumping from 80 to 220 leaves deep scratches that show through the finish. Pressing too hard: the weight of the sander is enough; extra force just generates heat and clogs the disc. Ignoring dust collection: dust on the workpiece fills the abrasive with debris and ruins cuts. Using the wrong pad backing: soft pads for finish work, firm pads for material removal. Sanding through veneer: keep the sander moving, especially on figured wood and thin veneer, or you will sand through in seconds.
Frequently Asked Questions
What is the best orbital sander?
Our team rated the Bosch ROS20VSC as the best random orbital sander overall, with a variable speed dial, micro-filter dust collection, and a pad dampening system that delivers swirl-free finishes. It earned our Editor’s Choice badge after 8 weeks of hands-on testing.
Is a random orbital sander good?
Yes. A random orbital sander combines orbital and rotational motion so no abrasive grain follows the same path twice. That makes it faster than a palm sander and cleaner than a regular orbital sander, which is why finish carpenters and furniture refinishers reach for one as their primary sander.
Should I get a 5 or 6 inch orbital sander?
Pick a 5 inch random orbital sander for finer finish work, tight corners, and smaller panels. Choose a 6 inch model when you want to cover larger surfaces quickly on furniture, doors, and tabletops. Most buyers are better served by a 5 inch pad because it handles more use cases.
Which random orbit sander has the least amount of vibration?
The Festool ETS 125 REQ-Plus has the lowest vibration in our roundup thanks to its hand-balanced vibration stop design, followed by the Bosch ROS20VSC with its pad dampening system and the Makita DBO180Z with its well-balanced body. All three are comfortable for hour-long sanding sessions.
What are the most common mistakes people make with a random orbital sander?
Skipping grits, pressing too hard, ignoring dust collection, using the wrong pad backing, and sanding through veneer. Walking through grits in sequence (80, 120, 180, 220), letting the sander’s weight do the work, and hooking up a shop vac solves most of them.
Final Verdict
After 8 weeks of testing 8 random orbital sanders across real furniture and finishing projects, our Editor’s Choice is the Bosch ROS20VSC. The variable speed, pad dampening, and micro-filter dust collection combine into a sander that handles everything from paint stripping to final-grit finishing on figured wood, and it does so at a price that does not require a shop budget.
For the best corded value, the DEWALT DWE6421K pulls harder than anything else in the lineup. For cordless convenience, the DEWALT DCW210B is the right pick if you already own 20V batteries, and the Milwaukee 2648-20 is the better choice for contractors on the M18 platform. Beginners should start with the BLACK+DECKER BDERO100 or SKIL SR211601, both of which deliver real random orbital performance at entry-level prices. And if finish quality is non-negotiable, the Festool ETS 125 REQ-Plus is worth every dollar.
Whichever best random orbital sander you pick from this list, hook it up to a shop vac before your first project. Dust collection is the single biggest upgrade you can make to your sanding results, and your lungs will thank you. Happy sanding in 2026.
