What reviewers say about the DeWalt DWE6421K 5 in. Single Speed Random Orbit Sander Kit
Two whitelisted testers cover the DWE6421K, but only Reviewed hands-on-tested it, naming it Best Overall for stripping paint in about three minutes versus roughly five for rivals. It praises the powerful 3-amp motor, comfort and decent dust collection, while flagging single-speed operation and that the tool jumps and pulls. Pro Tool Reviews is a spec preview, not benchmarked.
Tested by Reviewed (USA Today), Pro Tool Reviews
Consistently praised
- Fast, powerful 3-amp motor; fastest paint removal in the test (~3 min)
- Comfortable to hold in multiple positions
- Decent/quality dust collection, especially with a shop vac
Commonly flagged
- Single speed only
- Jumps and pulls; harder to control than rivals
Where reviewers disagree No genuine cross-source disagreement exists because only Reviewed benchmarked the sander; Pro Tool Reviews merely previewed manufacturer specs. Reviewed itself frames the strong 3-amp power as double-edged: it enables the fastest material removal but is also the direct cause of the control/jumping complaint.

Paint-removal time, 12x8-inch pine board, 80-grit: ~3 min (vs ~5 min for rivals)
It crushed its competition in terms of speed, removing the paint from a board in about three minutes, whereas the other random orbital sanders in this guide took around five.
It is comfortable to hold in multiple positions, and its dust collection system does a decent job
the same power that made such short work of the painted board makes this sander a bit difficult to control.
The DeWalt DWE6423K (variable speed) and DWE6421 (single speed) Random Orbit Sanders give you a couple solid options for woodworking and carpentry projects.

Source: dewalt.com (verified 2026-07-11) · corroborated by protoolreviews.com. DeWalt's official product page for the DWE6421K confirms the exact model: a 5-in. single-speed corded random orbit sander with a 3.0 amp motor spinning the hook-and-loop pad at 12,000 OPM, plus a one-handed locking dust bag and a dust port that fits the DWV010/DWV012 collectors (bag-and-port); it publishes no price. Pro Tool Reviews' "DeWalt Corded 5-inch Random Orbit Sanders" article corroborates these figures and disambiguates the exact variant, explicitly contrasting the single-speed DWE6421 (12,000 OPM) against the variable-speed DWE6423K (8,000-12,000 OPM); it also states the tool weighs 2.9 pounds and lists "Price: $75 (6421K)". Orbit diameter is given only in inches ("3/32 inch"), so orbitDiameterMm is left null rather than converted, and no m/s^2 vibration or dB(A) noise figure is disclosed.
