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.

Stunning watch!! Purchased for my boyfriend for his birthday. He is a bigger guy with a larger arm/wrist so the size of this watch looks great on him. He receives a ton of compliments on it, and it still catches my eye every time he wears it. Decent weight without being too heavy (he reports). Perfect to wear as a daily watch or dress up with
