Dumont Minute Man 44433 Collared Broach Bushing 12mm

Product Description

The DUMONT MINUTE MAN 44433 is a collared broach bushing designed to guide and support broaching tools during keyway and slot cutting operations. Style B-1 identifies the bushing geometry, featuring a plain collared design that seats securely against a workpiece or fixture to maintain precise tool alignment. At 12mm overall diameter, this bushing suits metric tooling setups commonly encountered in machining and fabrication environments. It weighs 0.06 pounds. Machinists and tool-and-die professionals install this component to reduce tool deflection and extend broach life during press or arbor operations.

This bushing is used in broaching applications where a collared, plain-style bushing is required to locate and stabilize the broach during the cutting stroke. Typical settings include machine shops, production lines, and maintenance facilities performing keyway cutting on shafts, hubs, gears, and similar workpieces. The 12mm diameter suits metric fixtures and press tooling where precise bushing fit is critical to cut quality and dimensional accuracy.

Key Features

• Style B-1 collared plain bushing geometry for consistent broach alignment
• 12mm overall diameter for compatibility with metric broaching setups
• Collared design seats against fixture or workpiece surface to control depth and positioning
• Lightweight construction at 0.06 pounds for easy handling and tool setup
• Sold individually - minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct-use collared broach bushing for metric broaching applications requiring a Style B-1 plain bushing at 12mm diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker familiar with broaching press operations. Before inserting or removing the bushing, ensure the broaching press or arbor press is fully de-energized and the ram is in the retracted position. The bushing should be seated squarely in the fixture or guide plate before initiating the broaching stroke. Do not force the bushing into an undersized bore, as this can cause cracking or misalignment that compromises cut accuracy.
