Dumont Minute Man 44445 Collared Broach Bushing 30mm

Product Description

The DUMONT MINUTE MAN 44445 is a Style C collared broach bushing with a 30mm overall diameter, designed to guide and support broaching tools during precision machining operations. This plain collared bushing holds the broach on center and protects the workpiece opening as the tool passes through. It is a standard toolroom consumable used in production and maintenance machining environments. The collar flange seats against the workpiece or fixture face, controlling broach entry depth and keeping the tool aligned. Machinists and toolroom technicians install and replace these bushings as part of routine broaching setups.

This bushing is suited for applications where a guided broach pass is required to produce keyways, splines, or other internal profiles in metal workpieces. Style C designates the collared plain configuration, which is the most common type used in fixture-based broaching. It fits standard broaching press setups found in job shops, production machining operations, and maintenance repair environments. The 30mm diameter matches a specific broach and workpiece opening size - confirm the bore and outer diameter specifications of your broach set before ordering.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the broaching press is fully de-energized and the ram is in the safe retracted position before changing or seating bushings. Verify that the bushing diameter matches both the broach shank and the fixture receiver before pressing operations begin. Do not force or modify the bushing to fit an incompatible fixture bore.
