Square Broaches

standard-square-sketchduMONT Minute Man® Standard Metric Square Broaches are designed to generate in one-pass a Standard Square hole in a previously cast or drilled round hole. Standard Square Broaches begin in an oversized pilot hole and generate the square hole while leaving small radii on the flats. Available from stock in the most common Metric sizes (4mm-25mm).

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.
