The DeWalt DWE6423K (variable speed) and DWE6421 (single speed) Random Orbit Sanders give you a couple solid options for woodworking and carpentry projects. The single-speed shaves some cost off the variable speed model. Aside from that difference, both models share nearly all remaining features and specs.
Both DeWalt 5-inch corded orbital sanders weigh 2.9 pounds and take a 5-inch hook and loop sanding pad.ย As part of DeWaltโs Perform and Protect line of power tools,ย both sanders reduce vibration to the user. They accomplish this through an internal counterweight system.
Ergonomics and Dust Collection
These twoย corded DeWalt Random Orbit Sandersย stand a squatย 5-1/2 inches (140 mm) tall. This givesย users the advantage of getting closer to the sanding surface. A rubber overmold, rubber dust skirt, and dust bag with a one-hand locking system round out the features. DeWaltโsย Universal Connector Systemย lets you attach to your dust extractor,ย reducing the amount of airborne dust.
Theย DeWalt DWE6421 5-inch Single Speed Random Orbit Sander features aย 3.0 amp motor that spins the pad at 12,000 OPM on a 3/32โ orbit diameter. The variable speed DeWalt DWE6423K delivers between 8,000 and 12,000 OPM. Either way, this makes the random orbit sander suitable for a variety of sanding applications. This sander works on many surfaces including wood, metal, and fiberglass.
Theย 5-inch Single Speed Random Orbit Sander (DWE6421) retails for around $75. Bumping up to variable speed tacks on a ~$25 premium (plan to spend just under $100). Both come with a 3-year limited warranty, 90-day money-back guarantee, and 1-year free service contract.
