A good quality bit.

I needed to slightly enlarge the 1 inch hole of a cast iron barbell weight plate that wont accept my 1 inch barbell. I was only using the last level (1-1/8 inch) of this bit to take off maybe a half-millimeter. After about 15 minutes, this bit was able to grind through about half the plate's thickness before the bit no longer had any bite. Afterwards I used a 1 inch flapper wheel abrasive grinder which smoothed the cut edge but it would take many wheels and hours to only use that to grind out the hole, and likely burn out my hammer drill. A half-round file was too big to file out the hole. Otherwise, I bet this bit does a great job on steel, just not cast iron which is asking too much.
