I have a knife I purchased from Woodcraft.
I would like to enlarge the holes in the knife from 5mm to 8mm so I can use a different set of pins.
I’ve tried a number of bits I own, including a carbide, which is supposed to cut hardened steel, and cobalt bit, to no avail. The steel handle just won’t drill. I know I can heat it and ruin the heat treatment but I would think that somewhere there are bits that can make short work of drilling it. The description says it is stainless steel, but I don’t know the hardness from the description. (Maybe the bits are really carbide bits and I just need to get a higher quality bit)
Does DMS have such a set of bits?
