The invention of the PCM rotary broach has revolutionized the technology that the broach cannot process blind hole polygons. The PCM rotary broach can be applied to all machining CNC equipment such as lathes, milling machines, and drilling machines. The equipment is formed in the last time: square, hexagon, plum blossom, spline and other polygons, and can save the sharp edges of the pcm rotary tool handle. Rotary broach can cover almost all metal material cutting (HRC<30).

PCM rotary broaches serve many industries: rotary punches are widely used in aerospace, aviation, automobiles, hardware and electronics, medical parts, transmission parts and other metal parts to process polygonal shapes. The rotary cutter can be used to make regular, irregular, sharp-edged, chamfered polygonal blind holes or rotary cutting tool holder through holes. In addition to standard hexagons and squares, grooves, ellipses, rectangles, trapezoids, stars or other special patterns can also be made.
