HSS metal drill bit polished centering tip R6M5 bright 4.2x75mm FIT 33836

FIT IT metal drill bits are designed for drilling holes in carbon and alloy steels, gray and malleable cast iron, non-ferrous metals, and plastic. The centering tip with a cross-grind allows for drilling without pre-center punching. Cutting forces are distributed evenly due to the 135-degree sharpening angle. The drill bits have the highest accuracy class A1 and drill holes with a precise diameter. The drill bits are manufactured by profile grinding, which increases drilling smoothness and the cleanliness of the finished holes. The flute shape complies with the DIN 338 standard and facilitates efficient chip removal during operation.
