Dumont Minute Man 33385 Plain Broach Bushing 3in Style E

Product Description

The DUMONT MINUTE MAN 33385 is a Style E plain broach bushing designed to guide and support broaching tools during keyway, spline, and other precision broaching operations. With a 3-inch outside diameter and a 6-inch bushing length, this bushing provides stable tool guidance across extended cutting depths. The plain bushing type means it installs directly into a matching bore or fixture without a flange, keeping setup compact. Machinists and tool-and-die professionals use this component in production and maintenance broaching applications where accurate alignment and repeatable positioning are critical. At 10.68 pounds, the part has the mass consistent with solid steel construction.

This bushing suits horizontal and vertical broaching setups in industrial manufacturing, maintenance repair, and toolroom environments. It is appropriate for use with a broach press or pull broach fixture where a 3-inch bore guide is required. The 6-inch length accommodates longer broach strokes and deeper workpieces. Trade professionals who perform keyway cutting, spline forming, or surface broaching on large-diameter bores will find this size appropriate for heavy-duty applications.

Installation Notes

Installation of broach bushings is performed by qualified machinists or toolroom technicians. Ensure the receiving bore or fixture is clean, free of burrs, and dimensionally correct before pressing the bushing into position. De-energize and lock out any hydraulic or mechanical press before handling tooling components. Do not use the bushing beyond its rated bore guidance application or force it into an undersized fixture bore.
