Dumont Minute Man 44502 Collared Broach Bushing 12mm

Product Description

The DUMONT MINUTE MAN 44502 is a Style A collared broach bushing with a 12mm overall diameter, designed to guide and support rotary broaches during precision machining operations. The collared design seats positively in the workpiece fixture or press, keeping the broach aligned and reducing deflection during the cut. This type of bushing is a standard consumable in tool rooms, production machining cells, and maintenance shops where keyways, hexagons, or other non-round profiles must be broached accurately. At 0.06 pounds, the 44502 is a compact, lightweight component that fits standard broach tooling setups.

This bushing is suited for use in manual arbor presses, hydraulic presses, and broaching fixtures wherever a 12mm guide is required. Style A refers to the collar configuration that indexes the bushing consistently in the holder, making it appropriate for repetitive production runs as well as one-off maintenance applications. Machinists, tool and die makers, and maintenance technicians working with rotary or push-type broaching systems are the primary users.

Compatibility

Designed as an OEM-style replacement or standard tooling component for broaching fixtures and arbor press setups requiring a 12mm collared guide bushing.

Installation Notes

Installation is performed by machinists or tool and die technicians. Ensure the press or fixture is fully de-energized and depressurized before removing or seating the bushing. The bushing should be pressed squarely into the holder to avoid cocking, which can cause premature wear or broach breakage. Inspect the seating bore for burrs or debris before installing a replacement bushing.
