Does it fit any rotary tool?

It fits tools that accept 1/8-inch shank accessories, including Dremel rotary tools. It must be mounted on the 402 mandrel.

Is the mandrel included?

No. The pack contains 20 cut-off wheels only; the 402 mandrel is required and sold separately.

Can it cut hardened steel?

Yes, Dremel lists hardened steel, sheet metal and aluminum. Expect faster wear on hardened steel than on softer metals.

What is the wheel size?

The wheel is 15/16 inch (23.8 mm) in diameter and 0.04 inch (1.0 mm) thick.

Can I cut wood and plastic with it?

Yes, it handles thin wood and plastic as well as metal. Keep cuts shallow and let the wheel do the work.

Why did my wheel break?

Cut-off wheels are brittle. Bending the wheel, forcing it, or pressing sideways instead of straight into the cut causes breakage.

Our take on the Dremel 420 15/16" Cut-Off Wheel Rotary Tool Accessories

The Dremel 420 is a 15/16-inch reinforced cut-off wheel for rotary tools, sold in packs of 20. Its 0.04-inch thickness lets it slice hardened steel, sheet metal, aluminum, thin wood and plastic, and cut slots in rusted or stripped bolts. It mounts only on the 402 mandrel with a 1/8-inch shank, so it fits Dremel rotary tools and most other rotary tools that take 1/8-inch accessories. Owners rate it highly for clean, fast cuts; the main trade-offs are wear on hard steel and breakage if the wheel is bent or forced.
