Square Broaches

duMONT Minute ManĀ® Full Square Broaches are designed to generate a Full Square hole in a previously cast or drilled round hole in one pass. The broach leaves no radii on the flats of the broached piece and the pilot diameter equals the finished full square size. Full Square Broaches are available from stock in the most common American Standard sizes (3/16″-1/2″).

Specials: We are fully equipped to manufacture Special Standard and Full Square Broaches to your specifications. All standard items are available with TiN, or TiAlN coatings. Please contact factory for details.
