Metal drill bit 4mm Cobalt (HSS-Co 5% M35 P6M5K5 steel) DIN 338 (blister 1 pc) Kranz KR-91-0505

KRANZ metal drill bit is manufactured according to DIN 338 standard and is used for drilling holes in materials such as steel, cast iron, stainless steel, alloyed and non-ferrous metals. It has a cylindrical shank and is used with drills, screwdrivers, and machine tools. The product is 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. Due to the 135-degree angle grinding of the cutting part, a more efficient entry of the tool into the material is achieved, which leads to an increase in service life and reduction of drill wear. Thanks to the ground profile, the drill bit maintains its precise position during drilling, which guarantees obtaining smooth and neat holes without cracks or chips.
