Great product. I had a broken bolt on a turbo and could not drill it out with a titanium or cobalt bit. The carbide bit went right through the hardened steel without becoming dull. I just used oil to keep it cool and did not drill too fast. I highly recommend this product.

Works where HSS & TIN drills cannot. Like most carbide tools it must be used correctly: proper speed & feed, do not subject to shock & use with coolant.

I used this drill bit to drill an Irwin Marples Chisel. I Drilled 2 holes to put screws through to make a flushing chisel. I used it on my drill press at 350 rpm with oil. Worked great, bit is still usable.

I have not used it yet. I read that it is what I need but high chance of breakage. I am willing to gamble on it to remove a broken tap
