Milwaukee 49-56-0117 2-Inch Ice Hardened Hole Saw Milwaukee 49-56-0117. Having to replace an old deadbolt in my steel front door I had to enlarge the smaller hole from the original part to 2 1/8". Most hole cutting bits are designed to create initial holes using the pilot bit. I didn't have that option. I created a jig cutting a hole in a 3/4" piece of plywood and clamping it to the door. I destroyed two "metal/wood" bits cutting through the thin steel. At a cost of $10 per bit I wasn't very happy. Someone needs to make a bit that is made specifically for cutting steel ...
