1/4″ Square Micro Rotary Broach | 8mm Shank Diameter x 28mm Overall Length
Polygon’s standard 1/4″ square Micro / Swiss type 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 1/4″ square broaches fit commercially available Micro and Swiss type broach holders. Nominal sizes meet ASME standards for square sockets 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.
