Dumont Minute Man 33345 Collared Broach Bushing

Product Description

The DUMONT MINUTE MAN 33345 is a Style C collared broach bushing with a 1-7/16 inch diameter and a 2-1/2 inch bushing length. Broach bushings guide cutting tools during broaching operations, maintaining precise alignment and protecting the workpiece and tooling. The collared design seats the bushing positively in the fixture, preventing axial movement during the cut. Machinists and toolroom professionals install this bushing in broaching fixtures and jigs where consistent bore alignment is critical to part quality and tool life.

This bushing is suited for use in production and toolroom broaching setups where a 1-7/16 inch bore guide is required. The Style C collared configuration is a standard industrial broach bushing form, appropriate for press-fit or slip-fit fixture installations depending on tolerance requirements. It is commonly used in metalworking environments including job shops, production facilities, and maintenance repair operations requiring precise hole-finishing guidance.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the fixture is secured and all power to associated machinery is disconnected before bushing removal or installation. Press-fit applications may require an arbor press and appropriate driver to seat the bushing without damage to the collar or bore. Verify bore tolerances in the fixture plate before installation to confirm proper fit class.
