This M42 cobalt drill bit is engineered for cutting through tough materials like stainless steel, hardened steel, cast iron, and alloy metals. Made from premium high-speed steel (HSS) with 8% cobalt content, the bit maintains its hardness at high temperatures, offering exceptional wear resistance and long tool life.
Ideal for industrial, fabrication, and mechanical use, the 135° split point design ensures fast starts and reduced walking, while the high cobalt content resists heat buildup during extended drilling.
