Dumont Minute Man 22256 Style C Broach Shim

Product Description

The DUMONT MINUTE MAN 22256 is a Style C broach shim used to control the depth of cut when broaching keyways in bores. Broach shims are inserted beneath the broach in the bushing to shift the broach cutting position, allowing the machinist or maintenance technician to achieve the correct keyway depth for a given shaft and hub assembly. This shim measures 0.0625 inches in thickness and is designed for use with a 0.25-inch keyway width. It is sold and packaged as a single piece, making it easy to stock individual sizes for precision adjustment work in machine shops, maintenance facilities, and industrial service settings.

Style C broach shims are used wherever a Style C push broach and compatible bushing are employed to cut keyways in hubs, sprockets, pulleys, and similar components. This shim is appropriate for applications requiring fine depth adjustment during single-pass or progressive broaching operations. Typical installers include machinists, millwrights, and industrial maintenance technicians performing shaft-to-hub fitting work on mechanical power transmission components.

Installation Notes

Broach shims are installed by machinists or maintenance technicians familiar with keyway broaching procedures. Before broaching, ensure the workpiece is securely fixtured and the press or arbor is properly aligned with the bushing. Select shim thickness based on the required depth of cut adjustment, and verify the shim seats flat beneath the broach within the bushing bore. Never exceed the rated capacity of the broach press, and follow the tooling manufacturer guidelines for lubrication and broach alignment.
