Dumont Minute Man 33304 Collared Broach Bushing

Product Description

The DUMONT MINUTE MAN 33304 is a Style A collared broach bushing used to guide rotary broaches and cutting tools during precision hole-finishing operations. With a bushing diameter of 7/16 inches and a bushing length of 1-1/8 inches, this component maintains accurate tool alignment in jig and fixture setups. The collared design seats against the fixture surface to control broach depth and prevent axial movement. Machinists and toolroom technicians install this bushing in drill jigs, broaching fixtures, and similar work-holding equipment where repeatable hole geometry is required.

This collared broach bushing is suited for use in precision metalworking environments including production machining, maintenance shops, and toolroom applications. It is designed for fixtures requiring a press-fit or slip-fit bushing to guide a broach or cutting tool through a workpiece. The Style A designation identifies the collar configuration, which is a widely recognized standard in jig bushing applications.

Compatibility

Designed as an OEM-style replacement or new-installation bushing for jig and fixture setups requiring a Style A collared broach bushing with a 7/16 inch bore diameter.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Before installation, ensure the fixture plate bore is clean and sized correctly for the intended fit class. Press-fit bushings should be installed with an appropriate arbor press - do not drive with a hammer directly on the collar. Verify tool clearance and bushing seating before running any broaching operation.
