MILWAUKEE RED COBALT HSS-G Metal Drill Bit Set (19-piece) 4932499764

Product information: Metal drill bits made from solid, extremely heat-resistant cobalt-alloyed steel (5% cobalt), ground to DIN 338. Polished surface; Suitable for drilling in high-alloy steel and metals with a tensile strength of 1000 N/m², such as acid- and heat-resistant steels and stainless steel; QUAD EDGE™ drill tip: a unique combination of a 135° cross-ground tip and 4 cutting edges: the 135° cross-ground tip facilitates easier centring, with no centre-punching required. The 4 cutting edges produce smaller chips, resulting in reduced heat build-up and a longer service life; Variable spiral geometry for faster chip removal and reduced heat build-up; Reinforced drill core: the innovative core has a conical design and becomes thicker towards the shank. Strengthens the drill bit and increases the service life of the spiral; 3-flute shank from a diameter of 5 mm for a better grip in the drill chuck; Colour: bronze.
