Dumont Minute Man 33302 Collared Broach Bushing 5/16 in

Product Description

The DUMONT MINUTE MAN 33302 is a Style A collared broach bushing used to guide and support broaching tools during keyway and spline cutting operations. The collar provides positive seating and axial positioning within the work fixture, keeping the broach aligned throughout the cut. This bushing measures 5/16 inch in diameter with a 1-1/8 inch bushing length. It is a precision tooling component installed by machinists and tool-room technicians working with rotary or push-type broaching equipment. Proper bushing selection directly affects cut accuracy and tool life.

The 33302 is suited for production and maintenance machining environments where keyway broaching is performed on hubs, sprockets, gears, and similar workpieces. Style A identifies the collar geometry, which is the standard configuration for use with matching fixture plates and broach press setups. The compact 5/16 inch bore makes this bushing appropriate for smaller shaft and bore applications common in light industrial and precision assembly work.

Key Features

• Style A collared design provides positive axial location in broaching fixtures
• 5/16 inch diameter bore guides the broach with close tolerances
• 1-1/8 inch bushing length offers adequate tool support through the cut
• Collar seats flush against fixture surface to prevent bushing migration during operation
• Single-piece unit with no assembly required

Compatibility

Designed as a standard Style A collared broach bushing for use with matching broaching fixture plates and press setups that accept 5/16 inch guide bushings.

Installation Notes

Installation is performed by tooling or machining personnel as part of broach fixture setup. The bushing should be seated fully into the fixture plate before the broach press cycle begins. Inspect the bushing bore for wear or scoring before each use and replace if tolerance is compromised. Secure the fixture assembly per the equipment manufacturer guidelines before initiating any broaching stroke.
