Bosch 21 Piece Cobalt Metal Drill Bit Set


Could these be the toughest cobalt metal drill bits on the market we wonder? Drill Hog claims that the melting point of the special cobalt M42 steel which they have been manufactured from is 2,853 degrees Fahrenheit. Which is pretty impressive stuff!

These drill bits mean business and they can drill through the toughest metals such as stainless steel, grade 8 bolts and spring steel. The pieces have been heat treated for extra hardness and have a 135 degree split point tip to prevent “walking” and a tri-flat shank which additionally prevents “spinning” in the chuck.

Another thing we liked was that the Drill Hog Drill Bit Set comes with a lifetime warranty which means that they will replace any broken parts, should any breakages occur.
