Cobalt high-speed steel heavy-duty drills are harder and stronger than standard high speed steel and are designed for drilling tough materials such as stainless steel. The
135º split point enables accurate positioning and less thrust when drilling. Industrial quality for drilling materials that have high hardness and tensile strength such as cast iron, bronze, hardened steel & stainless steel.
