Sanders: The Final Step Between Good and Great
Sanding is where surface quality is won or lost. A great piece of woodworking with poor sanding looks amateur; a modest piece sanded to a silky finish looks professional. DeWALT and Milwaukee both produce capable sanders across random orbit, belt, and detail categories. Here’s how they compare in 2026.
DeWALT DCW210: The Random Orbit Standard
DeWALT’s DCW210 20V MAX random orbit sander runs at variable speed from 8,000–12,000 OPM with a 5-inch hook-and-loop pad. Its paper clamp system — a genuine rarity on cordless sanders — accepts both hook-and-loop and standard PSA discs. The dust bag captures fine dust effectively, and the low-profile body reduces hand fatigue during extended sessions. At 2.0 lbs with battery, it’s one of the lightest professional random orbit sanders available. Variable speed is essential: lower speeds (8,000–9,000 OPM) prevent swirl marks on soft wood and final finish passes; higher speeds (11,000–12,000 OPM) cut faster on paint removal and aggressive stock removal.
Milwaukee M18 FUEL 2648-20: Power and Dust Control
Milwaukee’s M18 FUEL random orbit sander steps up with variable speed from 7,000–12,000 OPM and an integrated vacuum port that connects directly to Milwaukee’s M18 wet/dry vacuum for near-dust-free sanding. For shops prioritizing dust control — cabinet shops, indoor refinishing work — this connectivity is a significant advantage. The POWERSTATE motor maintains consistent OPM under varying pressure, preventing the speed drop that causes uneven sanding patterns. At 2.3 lbs with battery, it’s slightly heavier than the DeWALT but the power consistency compensates.
Belt Sanders: DeWALT DCS331 vs Milwaukee 2645-20
For aggressive stock removal and edge sanding, belt sanders are unmatched. DeWALT’s cordless belt sander on 20V MAX handles 3×18-inch belts at 820 ft/min — adequate for most stock removal and floor patching applications. Milwaukee’s M18 belt sander runs 3×18-inch belts at 850 ft/min with a tracking adjustment that’s easier to dial in on the fly. Both accept standard 3×18 belts from any manufacturer.
Detail Sanders: Tight Spaces and Profiles
For sanding profiles, inside corners, and tight spaces where a round pad won’t fit, both brands offer detail (mouse) sanders with triangular pads. Milwaukee’s M12 detail sander is exceptionally compact and lightweight for delicate detail work; DeWALT’s XTREME 12V detail sander matches it closely. These are specialty tools that complement rather than replace a random orbit sander.
Abrasive Selection Matters As Much As the Tool
Always use quality abrasives — Diablo, Mirka, and 3M all make significantly better hook-and-loop discs than generic alternatives. Use the correct grit progression: 80 grit to remove material/scratches, 120 for smoothing, 180 for pre-finish prep, 220 for final sanding before the first coat. Never skip more than one grit step — jumping from 80 to 220 leaves deep scratches that show through finish.
The Verdict
For general woodworking and light finishing: DeWALT DCW210 wins on weight and dual-attachment compatibility. For dust-critical environments and sustained power consistency: Milwaukee M18 FUEL 2648-20. Find both at Pro Tools Hub.
