This is the HSSE Spot Weld Drill Bit which contains special cobalt alloy and lasts twice as long as HSS bits. This bit features an 8 mm diameter cutting face.



O

ur 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 1-47/64" L x 5/16" in 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.

Benjamin H. ★★★★★

The cobalt alloy really makes a difference—I drilled through several layers of sheet metal on an old truck and the bit still feels sharp. Was done with the job in half the time my old HSS bits would have taken.

Henry T. ★★★★★

Took off the spot welds on my car door in no time, and the 8mm cutting face is exactly the right size for those tight spots. It’s held up through a dozen holes so far without dulling, which is more than I can say for the last bit I tried.

Brian X. ★★★★★

The cobalt alloy in this bit made quick work of some stubborn spot welds on my project, and it’s still sharp after several uses. I’m impressed it’s lasting longer than my old HSS bits without dulling.
