4mm Hex Micro Rotary Broach | 8mm Shank Diameter x 28mm Overall Length

Polygon’s standard 4mm hexagon Micro / Swiss 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 hexagon broaches fit all commercially available Micro and Swiss broach holders. Nominal sizes are slightly oversize and provide excellent clearance for hex keys and Allen wrenches. Standard pressure relief vent holes 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.
