Milling reamer is a cutter for precise hole machining and applys to CNC machine tools ,automobile and aviation. 1 The carbide rods are imported from Germany, promising the quality and precision of cutter. Optimal cutting edge design and precise making. 2 Super TiALN reduces the coeffiction of friction and improves the tool's life. 3 Made by world latest 5-AXIS tools grinder, promising the quality and precision. 4 It is regarded as finish cutting of customized small hole with dia20mm. The accuracy of hole is to 7 level, and correct the deviation of hole position, so the accuracy of machining is to 0.003-0.005. 5 The excellent cutting edges and flutes ensure that the chip-breaking and chip-flowing proceed smoothly during drilling.
