Rotary Tool Accessories

Cut-Off Wheels and Rotary Cutting Bits

The wheel mount, the material and the room around the cut determine which options belong on your shortlist. A wheel that fits the tool can still be wrong for the part you want to cut.

What to check before buying

Choose by the manufacturer’s material guidance for the exact model. Then check wheel diameter and thickness for access. If you already own a mandrel, compare the wheel’s center coupling to its documented interface before buying a refill. For cutting bits that require a guide, check the guide and tool model as a separate part of the fit.

Check what the wheel is meant to cut

The EZ456 is a reinforced wheel for metal and the EZ476 is documented for plastics. Their outside diameters are similar, so the material guide and model number carry more weight than the diameter alone.

Leave room for the holder

A smaller 402 wheel can be easier to compare for a recessed cut. Check the center mount and clearance around the wheel before comparing refill packs.

Questions about this department

Do wheels with the same outside diameter use the same mandrel?

Compare the center interface separately. Dremel’s accessory chart identifies EZ Lock and screw mandrel models, and assigns compatibility by accessory.

Where should I check whether a wheel is intended for plastic?

Read the exact model’s manufacturer specification. Wheel color and the material mentioned on a neighboring listing are unreliable guides.
