Dumont Minute Man 44405 Keyway Broach Style C 5mm Hss

Product Description

The DUMONT MINUTE MAN 44405 is a Style C keyway broach manufactured from high speed steel, designed to cut precision 5 mm keyways in bores across a range of hub and gear applications. With a body width of 0.375 inches and an overall length of 11.75 inches, this broach handles cutting lengths from 0.391 inches up to 2.5 inches. It ships uncoated and requires one shim for proper depth setup. Machinists and tool-and-die professionals use this broach with an arbor press or hydraulic press to produce clean, accurate keyways in metalwork where a standard 5x5 mm key must fit.

The 44405 is suited for production and maintenance machining operations where a 5 mm keyway must be broached into steel, cast iron, aluminum, or similar materials. It is appropriate for shops performing gear, pulley, sprocket, and coupling installations that require a correctly sized keyway for power-transmission components. The broach is rated for a press force of 1,470 pounds, keeping it compatible with standard shop presses used in light-to-medium machining environments.

Key Features

• Style C keyway broach profile for standard 5x5 mm key compatibility
• High speed steel construction provides durability across repeated cuts in common metals
• Keyway width tolerance held to 0.1963 to 0.1972 inches for precise fit
• Cutting length range of 0.391 inches to 2.5 inches accommodates varied hub thicknesses
• One shim included setup requirement for correct broach depth positioning
• Uncoated finish suitable for use with cutting fluid to extend tool life

Compatibility

Designed for use with standard 5x5 mm keys per common power-transmission keyway applications. Requires one shim for correct depth setting; verify shim stack compatibility with your broach set before use.

Installation Notes

This broach is installed and operated by machinists using an arbor press or hydraulic press rated to handle the required press force. Always secure the workpiece firmly before pressing to prevent movement during the cut. Apply cutting fluid to the broach and bore before each pass to reduce heat and extend tool life. Never exceed the rated press force, and inspect the broach for chipping or wear before each use.
