Dumont Minute Man 22253 Style B Broach Shim

Product Description

The DUMONT MINUTE MAN 22253 is a Style B broach shim used to adjust cutting depth during keyway broaching operations. Sold as a single piece, this shim measures 0.042 inches thick and is designed for use with 5/32-inch keyway width broach sets. Broach shims are stacked beneath the broach to incrementally increase the depth of cut with each press stroke, allowing machinists and tool-room technicians to achieve precise keyway dimensions in bores. The 22253 fits the standard Style B shim format, making it a straightforward replacement or supplemental piece within an existing broach set.

This shim is suited for production and maintenance machining environments where rotary keyways must be cut to close tolerances. Common applications include fitting shafts, hubs, gears, pulleys, and sprockets in industrial and mechanical maintenance settings. Style B broaches are used across a range of bore sizes, and single replacement shims like the 22253 allow technicians to replace worn or lost components without purchasing a complete set.

Compatibility

Designed as an OEM-style replacement shim for use with Style B keyway broach and bushing sets requiring a 5/32-inch keyway width and 0.042-inch shim thickness.

Installation Notes

Broach shims are installed by qualified machinists or maintenance technicians using an arbor press or hydraulic press. Before broaching, ensure the workpiece is properly fixtured and the bushing is seated securely in the bore. Shims are stacked in the correct sequence beneath the broach to control cut depth per stroke. Follow the broach set manufacturer's recommended stacking procedure and never exceed the rated capacity of the press or broach tooling.
