The XSP is has stronger rigidity to make full use of high performance CNC machining centers and the newer high precision tooling. ●From the YAMAWA analysis of the machining concept for thread cutting taps that conform to conventional pilot Cemented Carbide Taps holes and review of the shape of the tap, we created the optimum flute design. ⑤ ●By further improving the shank precision and the shank circularity, it became possible to create a more accurate screw thread for high speed machining.
