A 36" flex shaft and aluminum pen-style handpiece keep the weight off your hand, and the speed dial goes down to 1,000 RPM. On Dremel? Add the 225 Flex Shaft to an 8240/8250.

Why no DeWalt pick? We couldn't confirm a Dremel-style, variable-speed cordless rotary tool in DeWalt's US line-up when we checked (October 2026), so we don't list one. If you're on DeWalt batteries, a Dremel 12V or a WEN kit is the simplest route.
