1.30mm Hex Rotary Broach | 8mm Shank Diameter x 1-1/4″ Overall Length
Polygon’s standard 1.30mm hex 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 1.30mm hexagon broaches fit all commercially available broach holders. Hexagon forms smaller than .079” across flats are too small for standard pressure relief holes. Smaller broaches remain solid to maximize broach strength. Standard broaching depths are 2x the across flat dimensions and provide maximum clearance. Custom options include premium broach materials, coatings, dimensions and tolerances.
