The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the single-speed DeWalt DWE6421K kit is the workhorse value pick that keeps surfacing in best-sander discussions. High-trust r/woodworking commenters describe "good ergonomics, good power, and decent passive dust extraction," and r/Tools owners call it "a well-made tool" whose dust collection was "reasonably good with the vacuum adapter." The 3.0-amp motor at a fixed 12,000 OPM gets credit for sanding "like a beast," and the shorter body design is noted for getting closer to the work. The most honest criticism comes from DeWalt's own community, where users say it "still vibrates a lot" even as they concede "the dust collection is great." Because it's single-speed, reviewers point those needing to sand plastics or veneers toward the variable-speed DWE6423 instead.
What reviewers liked
- Large verified-purchase base and repeated high-trust community endorsements
- Reviewers praise the 3.0-amp motor's stock-removal power and shorter, get-close body
- Comes as a kit with carry bag at a competitive price
Where it falls short
- Single-speed design limits use on plastics and delicate veneers
- DeWalt-community reviewers report noticeable vibration
- Onboard dust collection needs a vacuum adapter to perform well

The consensus value proposition is durability and simplicity: a kit with a carry bag at a sensible price, backed by a very large pool of positive verified-purchase reviews. For someone who mainly sands wood and wants a tool that holds up to daily abuse, the trust-weighted picture is strongly favorable, with vibration and the lack of speed control as the main caveats.
- 3.0 amp motor that spins the pad at 12,000 OPM
- Shorter height allows the user to get closer to work piece
- Separate counterweight design reduces vibration for improved comfort
- Rubber over-mold in all of the critical areas of the sander
- Improved dust-sealed switch to protect against dust ingestion for longer switch life
- Improved dust collection and one-handed locking dust bag
- Dust port is designed to fit directly to the DWV010 or DWV012 dust collectors
- To attach dust port to other vacuum systems with 1-1/4 in. hoses, use DWV9000 Universal Quick Connector
