The custom-designed Double Contour Single Flute Gundrill features an extended carbide length head feature. It reduces tool drift for the length of the cut, providing good TIR readings from entry of the part to the exit. The machining improvements are achieved by a special cutting drill contour with an added rear contour that acts like a guide pad while the drill remains in the bushing, keeping the tool on location. Once the drill is in the cut, these guide pads continue to force the tool to cut a straight path for the remainder of the operation.
This special-design contour technology is also available in the following Star SU product lines: single flute high performance gundrills, solid carbide single flute gundrills, and two flute two hole milled style gundrills.
