Pioneer Broach Company

Pioneer Standard Stocked Broaches

The benefits of "CNC Qualified" broaches include superior work-piece finish, perfect repeatability of the sharpening process and a consistently accurate tool. Increases in tool life are commonly found to be from 20% to over 300%. These improvements are the result of the even loading of all cutting teeth throughout the broach and strict adherence to the engineering specifications. Near perfect tolerances are held utilizing pre-formed plated borazon metal wheels along with high pressure heavy oil coolants. This process produces consistent tooth gullet forms without the heat and friction generated by conventional grinding.
