Port Contour Cutters

At Proto-Cutter we understand customer requirements for precision holes, which is why our porting tools are all ground between centers to ensure tool concentricity. They are form relieved so a simple face grind for resharpening can be done. Port tools are carbide tipped or high-speed steel. Our port tools can be altered to meet special ports. If a standard cannot be altered, a special port tool can be made. Coolant holes can be added in the flutes as an option.
