Total lenght: 2. 64 inch; working length: 1. 46 inch. Welcome to download. Cobalt steel - manufactured from m35 grade cobalt steel, for much faster cutting and extra longer life span, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, with up to twelve times when compared with an average HSS drill bit.

Smooth bit surface allows for nice clean holes. Precision ground - these bits are fully ground so that it's cutting diameter is seriously accurate and the lifespan is prolonged in comparison to non-ground alternativesroll forged bits. For metalworking - particularly successful in cutting through hard metalshardness less than HRC38° such as stainless steel and cast iron, although they can be used for softer materials like copper and aluminium, too.
