Makita 3-in x 21-in Belt Sander 9903
Best for most people stripping old finish who want one corded sander that handles paint, varnish, and bare wood with steady control.
Key specs are an 8.8 AMP motor, a variable speed control dial from 690 to 1,440 ft./min., and electronic speed control that maintains constant speed under load. It has an auto-tracking belt system that tracks the belt without adjustment, and it sands flush to the wall with the nose and side of the sander. The belt size is 3 inch by 21 inch, the overall length is 11-5/8 inch, and the net weight is 9.5 lbs. It has a long 16.4 ft. power cord, a dust bag is included, and the box includes 1 3 inch by 21 inch abrasive belt at 80 grit. It is double insulated and has a low noise design.
Pros:
- Variable speed dial from 690 to 1,440 ft./min. lets you slow down for old paint and veneer and speed up for bare wood.
- Electronic speed control holds speed under load, and the auto-tracking belt system keeps the belt centered without adjustment.
- Sands flush to the wall with the nose and side, and the long 16.4 ft. cord reaches across a room without an extension cord.
Con: At 9.5 lbs it is heavier than the light budget picks, and the dust bag is less effective than a shop vacuum connection, a point owners raise.
Owner review themes point to owners who praise the variable speed dial, the way the sander holds speed under load, and the auto-tracking belt that stays centered. Many say it has been a trade standard for years and value the quiet running and the long cord. The recurring complaints are the dust bag, which owners say is less effective than a vacuum hookup, and belt changes that can be tricky for beginners.

Check current price on AmazonDeWalt 20V MAX XR Brushless Cordless 3-in x 21-in Belt Sander DCW220B
Best for owners already on the DeWalt 20V MAX platform who want to strip finish without a cord in the way.
Key specs are 20V MAX XR, a brushless motor, and a 3 inch by 21 inch belt. It has a variable speed trigger and a 25 speed selection dial, and the maker page states up to 22 percent more power than a corded version. It is sold as a tool only, so the battery and charger are not included. It is designed for carpentry and woodworking professionals.
Pros:
- Cordless 20V MAX XR freedom with a brushless motor and a 25 speed dial for fine control over the removal rate.
- Up to 22 percent more power than a corded version, per the maker page, so it strips finish at a pace closer to corded sanders.
- Shares batteries with the large 20V MAX platform, so owners already on DeWalt need no new battery system.
Con: Sold as a tool only, so the cost of a battery and charger lands on top, and owners report heavy battery drain on long stripping sessions.
Owner review themes point to owners who praise the balance with a mid-size battery, the granular 25 position speed dial, and the dust port that takes a 35 mm hose or an AirLock connection. The recurring complaints are fast battery drain on tough stripping jobs, the tool only price with no battery included, and a dust bag that some owners wish worked better.

Check current price on AmazonMilwaukee M18 FUEL 3-in x 18-in Belt Sander 2832-20
Best for fast removal and cleaner indoor work, especially when a shop vacuum is part of the setup.
Key specs are M18 FUEL, a POWERSTATE brushless motor, and REDLINK PLUS intelligence. The belt speed is 1350 SFM max, with a variable speed dial from 1350 to 750 SFM.

It has a tool-free adjustable pommel for flush sanding, automatic belt tracking, a tool-free belt change lever, dual LED lights, and a lock-on button. A dust bag and universal hose adapter are included. The M18 REDLITHIUM HIGH OUTPUT HO6.0 battery is not included. It fits 3 inch by 18 inch belts only, and it is part of the M18 System of over 200 tools.
Pros:
- Fastest belt speed in this set at 1350 SFM max, with a variable dial down to 750 SFM for gentler passes.
- Collects over 80 percent of dust generated, and the universal hose adapter connects to a shop vacuum for cleaner indoor work.
- Tool-free belt changes, automatic belt tracking, and a tool-free pommel for flush sanding keep the work moving.
Con: Battery life is the recurring owner complaint, and it takes 3 inch by 18 inch belts only, so 3 by 21 belts from other sanders do not fit.
Owner review themes point to owners who praise the power, the way it strips old paint and varnish without bogging down, and the dust collection when hooked to a shop vacuum. The recurring complaints are short battery runtime, dust escaping when using only the included bag, and a few reports of belts tearing or the tool locking up.

Best for edges, baseboards, and tight spots where a standard sander cannot reach close to adjoining surfaces.
Key specs are a 7.0 Amp motor and a 3 inch by 21 inch angled belt that sands closer to adjoining surfaces. It has a 3-position adjustable handle, a retractable hood that exposes the top of the belt for tight spaces, and a flush, low-profile design for vertical surfaces.

- Three position handle and low-profile design make vertical sanding on baseboards and doors more comfortable.
- Corded power with no battery to charge, and a dust bag included in the box.
Con: Single speed with no variable speed dial, so delicate passes on thin veneer need a light touch, and the plastic housing warms up under heavy pressure on dense hardwoods.
Owner review themes point to owners who praise the light feel, the three position handle, and the angled belt that sands close to edges and baseboards. The recurring tradeoffs are the single speed, the plastic housing warming up under heavy pressure on dense hardwoods, and a light build that needs more downward pressure from the user.

Check current price on AmazonQuestions to ask before buying
How coarse should the first belt be when stripping old finish?
Start with 40 or 60 grit for thick paint and varnish, then move to 80 grit, then 120 grit before switching to a random orbit sander for the final passes. A coarse belt removes finish fast, but it also cuts deep scratches that take time to sand out, so do not start coarser than the job needs. On a test patch, try 80 grit first. If the finish comes off at a good pace, stay with 80 grit and save the 40 grit for stubborn spots. Keep the sander moving with the grain at all times, and never let it sit in one place while the belt is running, because a belt sander can dish a flat surface in seconds.
Should I choose a corded or cordless belt sander for stripping paint?
A corded sander suits long stripping sessions because it never runs out of power and usually costs less for the same motor size. A cordless sander suits quick jobs, work away from outlets, and rooms where a cord gets in the way, but owners in this set report fast battery drain on tough stripping work. If you strip a whole floor or a full set of cabinets, corded is the safer choice. If you strip one door or a few boards at a time and already own batteries on the same platform, cordless is convenient. Either way, buy a spare battery or plan charging breaks before you start, and keep the work area clear of the cord on a corded model.
How do I strip old finish without gouging the wood?
Use a slow belt speed on paint and veneer, a coarse belt only for the first pass, and light, even pressure. Let the weight of the sander do the work and guide it in long passes with the grain. Check the surface often by stopping the sander, lifting it off, and looking at the scratch pattern in raking light. If you see deep cross-grain scratches, you are pressing too hard or the belt is too coarse. Change belts before they clog, because a clogged belt skids and heats the finish instead of cutting it. Finish with a random orbit sander at 120 grit or finer, because a belt sander alone leaves a surface that shows through stain.
What safety steps matter when sanding old paint that may contain lead?
Old paint may contain lead, and sanding it creates dust that is hazardous to breathe and hard to clean up. If the paint predates 1978, assume it may contain lead until a test says otherwise, and follow local rules for lead-safe work. Do not dry sand paint you suspect contains lead without approved controls, and keep children and pregnant people out of the work area. When in doubt, stop and get the paint tested or hire a lead-safe contractor. For any stripping job, wear eye protection, hearing protection, and a dust mask or respirator rated for fine dust, and use dust collection or a shop vacuum where possible. Check the work for nails and staples before sanding, secure the workpiece with clamps, and always read the maker manual for your sander before starting. The maker manuals for the sanders in this guide all warn against sanding lead-based paint without proper precautions.
How do I keep dust down while belt sanding indoors?
Connect the sander to a shop vacuum through its dust port or hose adapter wherever the maker provides one, and empty the dust bag often, before it is half full, so airflow stays strong. Seal the room with plastic sheeting, close vents, and open a window for fresh air if the weather allows. Wear a dust mask or respirator even with dust collection running, because fine sanding dust escapes every bag and port. Sweep and vacuum the room with a vacuum fitted with a fine dust filter, and wipe surfaces with a damp cloth rather than dry sweeping, which puts dust back in the air. Change out of dusty clothes before entering living spaces, and wash hands before eating or drinking.
Frequently asked questions
Can a belt sander remove old paint and varnish?
Yes. A belt sander with a coarse belt removes old paint and varnish quickly from flat wood surfaces, doors, and floors. Start with 40 or 60 grit for thick coatings, then step up through 80 and 120 grit. It is not the right tool for curved parts, spindles, or inside corners, where a scraper or detail sander works better.
What belt size is best for stripping old finish, 3 by 18 or 3 by 21?
Both sizes strip finish well. A 3 by 21 belt covers more area per pass and suits floors, tabletops, and large doors. A 3 by 18 belt is shorter, lighter, and easier to control on smaller pieces. Buy the size your sander takes, and do not try to fit the wrong belt length, because the tracking and tension will not work.
Do I need variable speed to strip old finish?
Variable speed helps a lot. A slow belt cuts old paint instead of heating and smearing it, and it protects thin veneer and softwood from gouging. A single speed sander still strips finish, but you must control the cut with light pressure and careful passes. If you strip finish often, choose a variable speed model.
Is it safe to sand old paint with a belt sander?
It is safe only with the right precautions. Wear eye, hearing, and dust protection, use dust collection, and check the paint for lead first. Old paint may contain lead, so follow local rules and maker guidance, and do not dry sand paint you suspect contains lead without approved controls. When in doubt, get the paint tested.
What grit sequence should I use after stripping with a belt sander?
After the belt sander, move to a random orbit sander at 120 grit, then 150 or 180 grit for a finish-ready surface. Do not jump straight from 60 grit to 180 grit, because the fine paper cannot remove the deep scratches the coarse belt left. Wipe the surface clean between grits so loose grit does not scratch the next pass.
