We analyzed 31,000+ verified reviews and expert ratings across two top sanders. The dimensions below show strengths and trade-offs.
Price — Black+Decker Wins by $57
The DEWALT costs $99 while the Black+Decker costs just $42. That $57 difference buys you cordless freedom and variable speed.
In daily use, the Black+Decker is a no-brainer for budget buyers. You get unlimited runtime with the cord, but you're tethered to an outlet.
Choose the Black+Decker if you're on a strict budget. The DEWALT is worth the extra investment if you value portability.
Power Source — DEWALT Wins for Portability
The DEWALT runs on a 20V battery, the Black+Decker plugs into 120V AC. Cordless freedom means you can sand anywhere without extension cords.
In practice, this makes the DEWALT ideal for garage workshops and job sites. The Black+Decker works best near an outlet or with a long cord.
Buy the DEWALT if you move around a lot. Stick with the B&D if your workbench is near a plug.
Orbits Per Minute — Black+Decker Wins for Speed
Black+Decker revs to 16,000 OPM, exceeding DEWALT's 12,000 max. This fixed speed removes material quickly, especially on edges.
For daily use, the DEWALT's variable speed lets you dial down for finishing. The Black+Decker's high speed can be aggressive for fine work.
Prefer Black+Decker for fast stock removal. DEWALT for versatility across grits.
Pad Size — DEWALT Wins for Coverage
DEWALT's 5-inch round pad handles large surfaces like tabletops and cabinets. The Black+Decker's rectangular detail pad is tiny, focusing on corners.
In practice, the DEWALT completes big jobs faster with fewer passes. The Black+Decker requires patience on open areas.
Pick DEWALT for wide sanding projects. B&D for tight spots and detail work.
Variable Speed — DEWALT Wins for Control
DEWALT offers a variable-speed dial from 8,000 to 12,000 OPM. The Black+Decker runs at a single high speed.
This matters when switching between rough sanding and fine finishing. You can slow the DEWALT to prevent gouging, then speed up for material removal.
If you work on multiple surfaces, DEWALT's adjustability is a game-changer. For one-task sanding, the B&D's fixed speed is fine.
Dust Collection — Tie
Both sanders include effective dust collection systems. DEWALT uses a dust bag and port for vacuum attachment; Black+Decker has a canister.
Users report both capture most debris, keeping the workspace cleaner. The DEWALT port teams well with shop vacs for near-dustless operation.
Neither dominates in this category. Both are adequate for most sanding tasks.
Amperage — DEWALT Wins for Power
DEWALT's input rating is 3 Amps, while the Black+Decker draws 1.2 Amps. Higher amperage translates to consistent power under load.
In real use, the DEWALT doesn't bog down on stubborn paint or hardwood. The Black+Decker can slow on heavy material removal.
For continuous sanding, DEWALT's power advantage is noticeable. The B&D is fine for quick touch-ups.
Amazon Rating — DEWALT Wins by 0.3 Stars
DEWALT earns 4.8 stars from 13,616 reviews; Black+Decker a 4.5 from 18,933. Both are highly rated, but DEWALT sets the standard.
Common praise for DEWALT: runtime, build quality, and smooth operation. Black+Decker users love its price and compactness but note limited reach.
Any sander above 4.5 stars from thousands of reviews is trustworthy. The DEWALT's rating edge aligns with its premium status.
