17mm Square Rotary Broach | 1/2" Shank Diameter x 1-3/4" Overall Length Polygon’s standard 17mm 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 17mm square broaches fit all commercially available broach holders. Nominal sizes are slightly oversize and provide excellent clearance for shafts and sockets. 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. *Note: This form is typically too large for many rotary broaching applications. Part Number: S06750B

19/32" Square Rotary Broach | 1/2" Shank Diameter x 1-3/4" Overall Length Polygon’s standard 19/32" 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 19/32" 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. *Note: This form is typically too large for some rotary broaching applications. Call us to discuss your project.
