SABIT cobalt drill bits are manufactured from M35 or M42 high-speed steel containing 5-8% cobalt. This alloy achieves a hardness of 68-70 HRC after heat treatment. Their standard diameter range is 0.5 to 20 mm with an ISO h8 tolerance. The helix angle is designed between 25 and 40 degrees for efficient chip evacuation. These bits operate at cutting speeds up to 30 meters per minute on hardened steels. The precise point angle is 135 degrees for optimal initial penetration. A Titanium Nitride TiN coating is sometimes applied to reduce friction and extend tool life.
The bit structure features two precisely profiled helical flutes for chip guidance. The overall length is typically 10 to 15 times the diameter. The shank area may undergo precision grinding. This enhances concentricity and reduces runout. These drills are suitable for stainless steels, tool steels, and cast iron. Under ideal conditions, tool life can reach 300 holes in 45 HRC steel. Cooling with emulsion or cutting fluid is essential for optimal performance. This process prevents cutting-edge chipping and thermal deformation.You can order and buy SABIT from Iran by contacting us through whatsaap and email.

Advantages of Buying Genuine Cobalt Drill Bits
Genuine cobalt drill bits are made from high-speed steel alloy with 5 to 8 percent cobalt content. This composition increases their heat resistance up to 1100 degrees Celsius. Their durability and lifespan in cutting hard steels are up to 10 times greater than standard drill bits. These bits require less cooling and increase work speed. Their high accuracy creates holes with a tolerance of less than 0.1 mm. The high initial cost is offset by reduced bit replacement and increased productivity. These tools are ideal for stainless steel, cast iron, and non-ferrous metals.
