Review on Titanium Nitride Coated Drill Piece by Robert Tyus

Bought these after a nightmare where they removed a broken starter pin from an industrial forklift (aka tractor). Had to use them this week (same job) and I've been happy with them. It cuts well and I don't feel like I'm going to break the bit in a spot that would make me want to do harikari. If they let me down in any fantastic way I will update the information.
