Dumont Minute Man 22219 Style F Keyway Broach 1 in Hss

Product Description

The DUMONT MINUTE MAN 22219 is a Style F keyway broach designed for cutting precise keyways in bores across a range of metalworking applications. Manufactured from uncoated high speed steel, this broach delivers reliable cutting performance on standard bore keyway operations. It measures 20.25 inches overall length with a 1-inch body width and accepts a cutting length range of 1 to 6 inches depending on the number of shims stacked. Seven shims are required for full-range operation. This tool is used by machinists and tool-and-die professionals working with arbor presses or broaching fixtures in production and maintenance environments.

The 22219 is suited for industrial and maintenance machining operations where a 1-inch wide keyway must be cut or finished to tight tolerances. It is applicable to both production runs and single-part repair work in shops equipped with an arbor press or hydraulic press capable of delivering the required pressing force. The keyway width tolerance of 1.0015 to 1.0025 inches makes it appropriate for applications demanding close-fit keyway dimensions in hubs, gears, sprockets, and pulleys.

Installation Notes

Installation is performed by qualified machinists using an arbor press or hydraulic press rated for a minimum of 11,100 pounds of force. Secure the workpiece firmly in a broaching fixture or bushing guide before pressing to prevent lateral movement. Apply cutting fluid to the broach and bore before each pass to extend tool life and improve surface finish. Never exceed the rated pressing force or attempt to drive the broach without proper guide bushing support.
