Title: Kobalt couldn't get through but Carbide did it!
Post by: theking on May 24, 2018, 05:51:15 PM

The previous owner broke a couple bolts on the Taco, not sure what he was trying to do. I tried to drill it out with Kobalt tip drill bits but it wasn't too effective so I picked up some Carbide tip bits and it finally broke through. Drilling out hardened steel is a PITA but glad I found the bits capable of doing it.... O0

The bit I used got pretty hot though:

Those are hammer drill bits.  I’ve never seen them use on steel but cement or things of that nature.  Good job though.
