These are our highest quality spot weld drill bits – Titanium Coated and Carbon Nitrated. This exceptional coating is extremely hard while offering a very low coefficient of friction, so it runs cool. The bit’s purple color comes from the carbon nitrating process, which makes this bit last 10 times longer than the standard HSS bit. Rockwell Hardness of 96, max temp rating of 1600 degrees. With this temp rating, you can use the MAX2U bit dry or with cutting oil. This bit is available in 8mm diameter.

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 1-47/64" 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.

Comfortable and breathable
Size: Medium, Color: Coyote Brown 4 Pairs
Super comfortable socks that breathe well in my Danner steel toes. Not a lot of shrinkage in the wash so they fit right over and over. Don’t slide down your legs.
