Cobalt metal drill bit set 3-8 mm R6M5K5 hexagonal shank (5 pieces) Kranz KR-91-0634

The set consists of metal drill bits manufactured according to the DIN 338 standard and used for drilling holes in materials such as steel, cast iron, stainless steel, alloyed and non-ferrous metals. The drill bits feature a hexagonal shank and are used with drills, screwdrivers, and machine tools. The products are made of high-quality M35 (P6M5K5) high-speed steel with the addition of 5% cobalt, which ensures resistance to overheating, long service life, and high efficiency. Thanks to the 135-degree cutting edge angle, a more efficient entry of the tool into the material is achieved, leading to increased service life and reduced drill wear. Due to the polished profile, the drill bits maintain precise positioning during drilling, guaranteeing smooth and neat holes without cracks or chips. For convenient transport and storage, the set is supplied in a heavy-duty plastic case. The kit contains frequently used diameters: 3, 4, 5, 6, 8 mm.
