Dumont Minute Man 44494 Style F-1 Keyway Broach 25mm Hss

Product Description

The DUMONT MINUTE MAN 44494 is a Style F-1 keyway broach manufactured from high speed steel (HSS) for cutting 25 mm wide keyways in ferrous and non-ferrous workpieces. With a broach body width of 1 inch and a cutting length range of 1 to 6 inches, this tool handles a wide range of hub depths in a single pull setup. The overall length of 20.25 inches provides the reach needed for press-type broaching operations. Four shims are required for this broach, allowing the operator to set precise depth increments during successive cuts. The uncoated HSS construction is suited for general-purpose keyway work where dimensional accuracy is the priority.

This broach is designed for industrial and trade applications requiring precision keyway cutting in pulleys, gears, sprockets, and similar hub components. It is used with an arbor press or hydraulic press in machine shops, maintenance facilities, and manufacturing environments. A pressure requirement of 12,300 pounds governs press selection. The 25 mm x 14 mm standard metric key size compatibility makes this broach appropriate for metric-standard drivetrain and power transmission components. Machinists, millwrights, and tool room technicians are the primary users of this product.

Installation Notes

This broach is installed and operated by machinists or millwrights using an appropriate press setup. Always verify that the press capacity meets or exceeds the 12,300-pound pressure requirement before beginning the cut. Secure the workpiece firmly in a broaching fixture and apply cutting fluid to the broach and bore to reduce friction and extend tool life. Advance depth incrementally using the required shims and inspect the keyway dimension after each pass.
