Rotary Tool Accessories

Mandrels, Collets, Chucks and Accessory Kits

Shop for the connection you need before comparing piece counts. The tool model, the fitted holder and the accessory all contribute separate dimensions and compatibility checks.

What to check before buying

For a mandrel, check its shank against the tool and its accessory interface against the wheel or head. For a replacement chuck, use the exact tool model as well as the accepted diameter range. Proxxon lists several tool exceptions for its 28941 chuck. For a kit, compare the included carriers and the replacement accessories you are likely to need later.

Separate the two fits

A mandrel connects the accessory to the tool. The mandrel must fit the tool’s holder, and its working end must match the accessory. For a chuck, check tool model compatibility before using the advertised shank range.

Count the mounts you will actually use

A kit can add many repeated consumables without adding more holders. Compare the included 401, 402 or EZ402 where they are documented, then check the refills you expect to replace.

Questions about this department

Will a chuck fit any tool if it accepts my accessory diameter?

Check the chuck’s fit on the tool as a separate requirement. Manufacturer model exceptions still apply even when the accessory’s shank fits the chuck range.

How can I compare two kits with very different piece counts?

List the jobs you need, then compare included mounts, distinct working shapes and refills for those jobs. Repeated wheels can add many pieces without adding more shapes.
