Dumont Minute Man 22252 Style B Broach Shim

Product Description

The DUMONT MINUTE MAN 22252 is a Style B broach shim designed to fine-tune keyway depth during broaching operations. Broach shims are placed under the broach bushing or in the broach guide to adjust the cut depth, allowing machinists and tooling technicians to achieve precise keyway dimensions without regrinding the broach. This single-piece shim measures 0.031 inches in thickness and is sized for a 1/8 inch keyway width. It is a standard consumable in production machining environments and job shops where keyway tolerances must be held tightly across multiple workpieces.

Style B broach shims are used in push broaching and press broaching setups where controlled keyway depth adjustment is required. This shim is suited for use in vertical or horizontal broaching presses working on hub bores, sprockets, gears, and similar components requiring internal keyways. Machinists use sets of shims in incremental thicknesses to dial in final keyway depth. This 0.031 inch shim represents a common intermediate step in that process. It is sold as a single piece, allowing technicians to purchase only the specific thickness needed.

Compatibility

Designed as an OEM-style replacement shim for Style B broach tooling setups requiring a 1/8 inch keyway width and 0.031 inch shim thickness.

Installation Notes

Broach shims are installed by qualified machinists or tooling technicians as part of a controlled broaching setup. Ensure the broaching press is fully de-energized and the ram is in the retracted position before placing or removing shims. Shims must be seated flat and free of debris to avoid skewed cuts or broach damage. Follow the tooling manufacturer guidelines and applicable shop safety procedures when adjusting broach depth.
