COBALT STEEL - Manufactured from M35 grade cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, ideal for repeated drilling in metalworking.
FOR STAINLESS STEEL - Particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Not for heat treated steel / hardened steel / high carbon steel. Please try to adjust the RPM when it fails to penetrate according to our suggested RPM chart.
SELF-CENTERING - The 135° quick-cut split points can penetrate metals quickly with less pressure without "walking" or "wandering". No center punch is needed.
5PC SET - The set includes 5pcs of 5/32-inch diameter M35 grade cobalt steel twist drill bits, packed in a convenient plastic case for easy taking to worksites.
