Dumont Minute Man 22207 Keyway Broach Style B 3/16 in

Product Description

The DUMONT MINUTE MAN 22207 is a Style B keyway broach ground from high speed steel and sized at 3/16 inches wide. It is used to cut keyways in bores, hubs, pulleys, and sprockets where a precise keyway slot is required for shaft-key drive connections. The broach body width is 3/16 inches, the overall length is 6.75 inches, and cutting lengths range from 19/64 inches to 1-11/16 inches. One shim is required for proper sizing during use. Installation is performed by machinists and toolroom mechanics using an arbor press or hydraulic press rated to the required tonnage.

This broach is suited for production and maintenance applications in industrial, manufacturing, and repair shop environments. It is used when creating internal keyway slots in ferrous and non-ferrous workpieces. The Style B designation refers to the broach body profile, which determines compatibility with matching broach bushings and shim sets. The uncoated finish is appropriate for standard cutting applications across a range of common workpiece materials.

Installation Notes

Keyway broaching is performed by qualified machinists using an arbor press or hydraulic press capable of supplying adequate force for the workpiece material and broach size. The workpiece bore and bushing must be properly aligned before pressing to avoid broach damage or deflection. One shim must be installed over the broach body as specified before the final sizing pass. Always secure the workpiece firmly and ensure the press ram travels straight through the bore axis.
