5/16″ Square Rotary Broach | 8mm Shank Diameter x 1-1/4″ Overall Length
Polygon’s standard 5/16″ square rotary broaches are made from high quality M-2 high speed steel and precision ground to tight tolerances for superior broaching performance. Ground shank diameters insure that Polygon’s 5/16″ square broaches fit all commercially available broach holders. Nominal sizes meet ASME standards for socket clearances and include pressure relief vent holes to reduce pressure and improve tool life. Standard broaching depths are 2x the across flat dimensions and provide maximum clearance. Custom options include premium broach materials, coatings, dimensions and tolerances.
