Dumont Minute Man 44411 Keyway Broach Style E-1 16mm

Product Description

The DUMONT MINUTE MAN 44411 is a Style E-1 keyway broach machined from high speed steel for cutting precise keyway slots in bores. With a 16 mm keyway width and a keyway height of 10 mm, this broach is designed for standard 16x10 mm metric key fits. The cutting length ranges from 1 to 6 inches, and the overall length (OAL) is 15.5 inches. The uncoated high speed steel construction delivers consistent performance in moderate-production broaching operations. Three shims are required for proper setup. Licensed machinists and tool-and-die professionals install this broach in hydraulic or arbor press applications where controlled keyway geometry is critical.

This broach is suited for industrial and production machining environments where metric keyway slots must be cut into shafts, hubs, gears, or pulleys. The Style E-1 designation follows the standardized broach style classification used for push-type keyway broaching. It is appropriate for use in shops handling moderate lot sizes requiring repeatable 16x10 mm keyway profiles. The 3/4-inch body width and 9,400 lb pressure rating position this tool for use with compatible broaching presses where adequate tonnage is available.

Key Features

• Style E-1 push-type keyway broach configuration for standardized press setups
• High speed steel construction for durability across moderate-production cycles
• 16 mm keyway width with a tight tolerance range of 0.6290 to 0.6304 inches for precise fits
• Cutting length range of 1 to 6 inches accommodates varying bore depths
• Requires 3 shims for proper broach height adjustment and alignment
• Uncoated finish suitable for use with standard broaching fluids and coolants

Compatibility

Designed for standard 16x10 mm metric keyway applications using Style E-1 push-type broaching setups with compatible hydraulic or arbor broaching presses capable of 9,400 lb of pressure.

Installation Notes

This broach is installed and operated by qualified machinists using a hydraulic press or arbor press rated for the required broaching pressure. Always ensure the workpiece bore is properly deburred and aligned before pressing the broach through. Use the correct number of shims as specified to achieve the proper keyway depth and to protect the broach from overloading. Apply broaching fluid or cutting oil to extend tool life and improve surface finish in the keyway slot.
