Dumont Minute Man 44500 Style E Keyway Broach Set 10pc

Product Description

The DUMONT MINUTE MAN 44500 is a 10-piece Style E keyway broach set designed for cutting precision keyways in the 16 to 18mm width range. Manufactured from high speed steel with a bright, uncoated finish, this set delivers the hardness and edge retention required for consistent broaching through steel hubs, gears, pulleys, and sprockets. The set includes plain bushings with a bushing diameter range of 52 to 65mm, allowing the broach to be properly guided and supported throughout the cut. Machinists, toolroom technicians, and skilled maintenance professionals rely on sets like this for close-tolerance keyway work on manual and CNC arbor presses.

This set is suited for shop and industrial maintenance applications where metric keyway sizing is required. Style E broaches follow a push-type configuration, typically used with an arbor press or hydraulic press to drive the broach through the bore. The 16 to 18mm keyway width range covers common metric shaft-and-hub configurations found in power transmission assemblies. The included plain bushings ensure proper broach alignment during the cut, reducing deflection and protecting the workpiece bore finish. The set ships in a plastic and wood storage box, keeping broaches organized and protected between uses.

Installation Notes

Broaching should be performed by a qualified machinist or toolroom technician using a properly sized arbor press or hydraulic press. Always ensure the workpiece is securely fixtured and the bushing is correctly seated in the bore before pressing. Apply cutting oil to the broach and bore to reduce heat and extend cutting edge life. Never exceed the press capacity rated for the broach size in use.
