Dumont Minute Man 33340 Collared Broach Bushing

Product Description

The DUMONT MINUTE MAN 33340 is a Style C collared broach bushing designed to guide broaching tools accurately through a workpiece during machining operations. The collar provides a positive stop against the workpiece surface, ensuring consistent broach depth and alignment on every pass. With a bushing diameter of 1-1/8 inches and a length of 2-1/2 inches, this bushing fits precision tooling setups in production and job-shop environments. It weighs 0.68 pounds. Machinists and toolroom professionals install this type of bushing as part of a broaching fixture to maintain tool alignment and extend broach tool life.

This collared broach bushing is suited for use in horizontal and vertical broaching applications on machining centers and dedicated broaching presses. It fits into broach fixture plates where a 1-1/8-inch bore is required. Style C designation indicates the collared design, which seats flush against the fixture plate surface and prevents the bushing from being drawn through the fixture during the pull stroke. Typical applications include keyway broaching, spline broaching, and round hole finishing in metal workpieces across general manufacturing and toolroom settings.

Compatibility

Designed as an OEM-style replacement or direct-fit component for broaching fixtures requiring a Style C collared bushing with a 1-1/8 inch diameter bore and 2-1/2 inch length.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the broaching press or fixture is fully de-energized and at rest before removing or seating the bushing. The bushing should be pressed or driven into the fixture plate bore with appropriate tooling to avoid damage to the collar or bore surface. Verify bushing seating and alignment before resuming any broaching operation.
