4mm Square Micro Rotary Broach | 8mm Shank Diameter x 28mm Overall Length
Polygon’s standard 4mm 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 4mm square broaches fit commercially available Micro and Swiss type broach holders. Standard pressure relief vent holes reduce pressure and improve tool life. Standard broaching depths are 2x the across flat dimensions and provide maximum clearance.
