Dumont Minute Man 22305 Keyway Broach Style B 1/8 in

Product Description

The DUMONT MINUTE MAN 22305 is a Style B keyway broach machined from high speed steel and designed for cutting precise keyways in bores, bushings, and hubs. With a keyway width of 0.125 inches and a width tolerance of 0.1252 to 0.1262 inches, this broach delivers tight, repeatable cuts suited to production and maintenance environments. The cutting length measures 1-11/16 inches, and the overall length is 6-3/4 inches. One shim is required for proper depth setup. A surface coating extends tool life under typical cutting loads. Machinists, tool-and-die makers, and maintenance technicians install this broach using an arbor press or hydraulic press.

The 22305 is used in applications requiring an internal keyway to transmit torque between a shaft and a mating component such as a gear, pulley, or sprocket. It is suited to light industrial and maintenance repair operations where a 1/8-inch keyway is the specified fit. The broach body width of 3/16 inches guides the tool through the bore, and the required press force is rated at 720 pounds. This broach is appropriate for single-piece and low-volume production runs where a dedicated broaching machine is not available.

Key Features

• Style B broach geometry for standard keyway profiles
• High speed steel construction for durability across common engineering materials
• Keyway width of 1/8 inch with a tolerance of 0.1252 to 0.1262 inches for precise fits
• 1-11/16 inch cutting length accommodates typical hub and bushing thicknesses
• Coated finish to reduce friction and extend cutting life
• Requires one shim for correct depth positioning during setup

Compatibility

Designed as an OEM-style replacement and standard tool for applications specifying a 1/8-inch Style B keyway broach in high speed steel with a 3/16-inch body width.

Installation Notes

This broach is installed by machinists and maintenance technicians using an arbor press or hydraulic press rated to handle the 720-pound required press force. Always confirm the bore diameter and keyway specification match the broach dimensions before pressing. Install the required shim to set the correct cutting depth before each use, and secure the workpiece firmly to prevent movement during the cut. Never exceed the broach's rated press force or attempt to use the tool in a rotating machine spindle.
