Weiler 56490 Cut-Off Wheel Mandrel

The Weiler 56490 is a cut-off wheel mandrel designed to mount abrasive wheels onto rotary tools. It connects wheels with a 3/8 inch unthreaded hole to a tool with a 1/4 inch straight shank. The mandrel measures 2 1/4 inches in overall length and is supplied as a new component for workshop use.

Suits wheels 2 to 3 inches diameter

This mandrel suits operators mounting cut-off wheels between 2 and 3 inches in diameter and 1/8 to 1/4 inch thick. It is not for users needing to mount larger diameter wheels, thicker abrasive discs, or wheels with threaded or different hole sizes. Builders requiring alternative shank dimensions should look at other mounting solutions.

3/8 inch unthreaded hole mounting

The critical specification is the 3/8 inch unthreaded hole abrasive mounting connector. This mandrel only fits wheels with that exact centre hole configuration; wheels with threaded centres, larger bores, or smaller bores will not mount securely. Verify the wheel centre hole before purchase.

Questions about this item

How do I confirm the mandrel is seated correctly after mounting a wheel?

The 1/4 in straight shank should lock firmly in the tool chuck with no wobble, and the wheel must sit flat against the flange without lateral play when spun by hand.

What comes in the package and what must I supply separately?

The mandrel itself is included; you must provide a compatible cut-off wheel between 2 in and 3 in diameter and 1/8 in to 1/4 in thick.

Which version of the 56490 should I choose for a 3 in wheel?

The single 56490 model covers the full 2 in to 3 in diameter range, so no alternate version is needed for a 3 in wheel.
