I'm having a lot of trouble drilling my 13/16" holes with the Harbor Freight step bits on my 3 keggles. I'm only getting a couple of holes before the bits give out at the last 2 steps. I'm using a drill press at low speeds (500 - 1500 rpm) and oiling and gone through 2 bits already. I'm going very slow and making sure I don't overheat the bit or ss. I keep reading about people that don't have any trouble, so I don't know what I'm doing wrong. This is very frustrating. These bits are titanium nitride coated. I am thinking about trying a Rock River or Lenox step bit that is steam oxide coated but they are $50 to $100+.
I would appreciate any suggestions.
