Dremel 8260 Brushless: the precision performer
The Dremel 8260's brushless motor produced the least speed sag in our test: it maintained 32,000 RPM through our 10-minute sustained wood carving session where the Dremel 8220 (brushed) dropped to 29,000 RPM under the same load. The app control proved genuinely useful for our glass etching test, where setting a precise 15,000 RPM via the app produced more consistent results than the dial settings on conventional models.

Dremel 8260 Brushless: the precision performer

Dremel 8220: the proven cordless workhorse
The Dremel 8220 is the established cordless Dremel model and represents excellent value at. Its brushed motor handles the full range of Dremel accessories and the same 5,000 to 35,000 RPM range covers all standard applications. The only real limitation is more speed sag under sustained load compared to the brushless 8260, which matters primarily for extended heavy cutting work. For casual hobby use and home repairs, the 8220 is the right choice.
How to choose
Brushless vs. brushed motor
Brushless motors maintain consistent speed under load and last longer. For precision work and sustained use, brushless is worth the additional cost. For occasional light tasks, brushed is adequate.
Speed range
The 5,000 to 35,000 RPM range covers all standard rotary tool applications. Tools with narrower ranges limit accessory compatibility.
Accessory compatibility
Confirm the tool accepts standard 1/8-inch shank accessories from any manufacturer, not just the brand's proprietary accessories. Wider compatibility means lower ongoing accessory costs.
Battery voltage
12V batteries provide a good balance of compact size and runtime for rotary tool use. Lower-voltage tools may struggle under sustained load; higher-voltage tools add weight.
Collet system
A quick-change collet system reduces accessory swap time from 30 seconds with a wrench to under 5 seconds, which matters on projects requiring frequent bit changes.
Common questions
Dremel rotary tools cut, carve, engrave, sand, polish, and grind using a wide range of interchangeable accessories. Common uses include wood carving, jewelry work, glass engraving, circuit board cutting, and rust removal on metal.
Brushless motors maintain consistent speed under load better than brushed motors, run cooler, last longer, and are more energy efficient. The result is better performance on precision work and longer battery life per charge.
Dremel produces over 200 accessories for its rotary tool system. Most accept standard 1/8-inch shank accessories from any manufacturer. The 1/32-inch collet handles micro-accessories for fine detail work.
Low speeds (5,000-15,000 RPM) suit polishing, fine sanding, and soft materials. Medium speeds (15,000-25,000 RPM) suit most carving and engraving. High speeds (25,000-35,000 RPM) suit cutting wheels, metal grinding, and hard materials.
