M42, Cobalt Drill Bits, For Hard Steels and Stainless

We recently just finished testing our M42 cobalt gold drill bits up against eight other brand cobalt drill manufacturers and found we have by far the best value when it comes to cobalt drill bits. First we found some of the companies out there say there bit is cobalt when in fact it is just a coated high speed steel. Beware of the words cobalt coated.   Cobalt (pronounced KOH-BOLT) is a hard, lustrous, gray metal, a chemical element with symbol Co and atomic number 27. The metallic cobalt was not discovered until 1735. Pure cobalt is not found in nature but small ammounts of it are found in rocks, soil, plants and animals. Basically found in the form of ores. Cobalt is usually not mined alone, and tends to be produced as a by-product of nickel and copper mining activities. Our M42 T-Plus 10% Boss Hog cobalt gold series is simply the best way to go when it comes to drilling hard materials.
