Dumont Minute Man 66632 Square Broach 6mm

Product Description

The DUMONT MINUTE MAN 66632 is a 6mm square broach designed for precision broaching operations in drive, fixture, and jig applications. The tool measures 6-11/16 inches in overall length with a pilot hole diameter of 0.2519 inches. Tolerance runs from 0.2362 to 0.237 inches, and the across-corners measurement falls between 0.33 and 0.332 inches. A 3/16-inch pitch and a length of cut ranging from 1/4 to 3/4 inches allow the broach to handle varied material depths. Maximum pressure at full length of cut is rated at 1,300 pounds. The uncoated tool finish suits standard broaching work in toolrooms and production environments.

This square broach is used wherever a precise 6mm square hole is required in a workpiece. Typical applications include machining keyways or square bores in drive components, fixtures, and jigs. The tool is suited for use in manual or hydraulic arbor presses and broaching press setups found in machine shops, maintenance facilities, and manufacturing environments. Operators requiring tight dimensional control in square broaching operations will find the stated tolerance and across-corners specs relevant to their fit requirements.

Installation Notes

This broach is installed and operated by machinists or toolroom technicians using an arbor press or dedicated broaching press. Ensure the workpiece is properly fixtured and aligned with the pilot hole before applying pressure. Do not exceed the rated 1,300-pound maximum pressure for the full length of cut. Use appropriate cutting fluid to reduce friction and extend tool life during the broaching pass.
