Dumont Minute Man 44439 Collared Broach Bushing 20mm

Product Description

The DUMONT MINUTE MAN 44439 is a Style C collared broach bushing with a 20mm overall diameter, designed to guide and support broaching tools during precision machining operations. This plain collared bushing holds the broach on center through the workpiece, reducing tool deflection and improving cut accuracy. Weighing 0.2 pounds, it is a compact, purpose-built tooling component used in production and job-shop environments. Machinists and tooling technicians install this bushing as part of a broaching fixture setup to maintain consistent hole geometry across repeated cycles.

This bushing is suited for metalworking applications where rotary or push broaching requires a guided support point. It fits into standard broaching fixtures and is appropriate for both light production runs and repetitive high-volume operations. The Style C collared design seats securely against the fixture plate, preventing the bushing from being pulled through during the broaching stroke. It is a stock tooling item used in machine shops, manufacturing facilities, and maintenance operations handling keying, spline, or shaped-hole work.

Key Features

• Style C collared design seats against fixture plate to prevent pull-through during broaching stroke
• 20mm overall diameter fits standard broaching fixture bores
• Plain bushing bore guides broach tool on center for accurate, repeatable cuts
• Lightweight at 0.2 pounds for easy handling and fixture assembly
• Single-piece unit with no assembly required

Compatibility

Designed as a direct-fit broaching fixture component for applications requiring a Style C collared plain bushing with a 20mm overall diameter. Confirm fixture bore and broach tool diameter before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with broaching fixture assembly. Ensure the fixture plate and bushing bore are clean and free of chips or burrs before seating the bushing. Power down and lock out all machine motion before handling tooling components. Verify bushing fit and seating against the fixture plate face before initiating any broaching cycle.
