Review on HOZLY Titanium Nitride Coated Carbide Cutting Tools by Michael Schafer

This drill bit was used to drill a hole in 1/2 inch thick stainless steel tubing for a jet burner. The first drill was drilled with a hand drill. I was impressed. If you're building a jet burner for cooking seafood, roasting turkey, etc., that's a bit. As with any micro beat, it should be taken lightly.
