Dumont Minute Man 33377 Plain Broach Bushing 2.5in Style E

Product Description

The DUMONT MINUTE MAN 33377 is a Style E plain broach bushing used to guide broaching tools accurately through a workpiece during the broaching process. With a 2.5-inch outer diameter and a 6-inch bushing length, this bushing provides stable tool guidance in press-type or pull broaching setups. It weighs 7 pounds, indicating a solid, heavy-duty construction suited for demanding production environments. Machinists and toolroom technicians install this type of bushing in broaching fixtures to maintain alignment and reduce tool deflection, resulting in accurate, repeatable keyways, splines, and other broached profiles.

This bushing is appropriate for use in industrial machining operations where a plain-style guide bushing is required. Style E designates a specific dimensional standard and configuration recognized across the broaching industry. It is suited for production shops, toolrooms, and maintenance facilities handling medium-to-large bore broaching work. The 6-inch length provides extended guidance suitable for thicker workpieces or stacked-plate setups where additional tool support is necessary.

Key Features

• Style E plain broach bushing configuration for industry-standard fitment
• 2.5-inch bushing diameter accommodates medium-to-large broaching tool sizes
• 6-inch bushing length provides extended tool guidance for thicker workpieces

Compatibility

Designed as an OEM-style replacement or direct-fit broach bushing for fixtures and broaching presses requiring a Style E plain bushing with a 2.5-inch diameter and 6-inch length.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out the broaching press before handling or seating the bushing in the fixture. Ensure the fixture bore is clean and within tolerance before pressing the bushing into place. Do not force or drive the bushing with impact tools, as this can distort the bushing bore or damage the fixture.
