HSS-R Metal Drill Bit Set, 5 Piece

The 5-piece HSS-R metal drill bit set from kwb contains twist drill bits in diameters of 3, 4, 5, 6 and 8 mm with total lengths of 61 to 117 mm. Made from HSS 4241 with a hardness of 58-62 HRC, they are suitable for precise drilling in steel, grey cast iron, non-ferrous metals and hard plastics. While the right-hand cutting N-type geometry in accordance with DIN 338 ensures clean results, the roll-forged flute with fully ground chamfer improves chip removal. The 118° point angle with conical ground shank enables precise drilling. With a round shank and chamfered shank end, the drills ensure reliable power transmission in the drill chuck. They are packaged in a sturdy plastic case with Euro hole suspension.
