8MM COBALT BIT 5/16" 8X43.4MM

This is the HSSE Spot Weld Drill Bit which contains special cobalt alloy - lasts twice as long as HSS bits. This bit features a 8mm diameter cutting face. Our Spot Weld Drill Bits are made of top quality, German tool steel. This high-speed steel is mixed with a special cobalt alloy (EMO5-CO5), resulting in bits that can be expected to last twice as long as standard high-speed steel bits. Tests in our Spot Mill (item #90150) have resulted in over 100 spot welds removed. These advanced bits also work great in any other spot weld cutter. Measuring 1_" long x 5/16" diameter, they can be used in any drill which runs between 700 to 1800 rpm. Of course, as with any cutting tool, use of a cutting oil will greatly increase the life of the tool. Once you use one of our Spot Weld Drill Bits, you'll never go back to hole-saw-type cutters again.
