Carbide ALTiN-Titanium Nitride Coated Spot weld. Designed to effectively cut auto body panel spot welds - Boron Steel. Carbide ALTiN-Titanium Nitride Coated. Recommended RPM 900 - 1000. Designed to cut spot-welds in Boron steel.
This bit is perfect for industrial and scientific purposes. As my tests showed, it can cut through even the toughest of materials with ease... The point design is well thought out and ensures an accurate cut every time. The only con I can think of is that it may be a bit expensive for some buyers. Overall I highly recommend this drill bit for those in need of a reliable tool..
Pros
Efficient and quick method for removing spot welds
Cons
Requires some skill and experience to use effectively
This bit fell short of its competition. I needed a bit fast and the listing said I would receive it next day (it took over 3 days to receive). What's even more frustrating is that when I finally pick up the chisel, the center piece is cut too small to catch and act as a "pilot" for the drill. Essentially useless. After trying a few times I finally gave up and bought another brand - worked like a charm! I would not recommend this to anyone.
