Last summer I loaned my 1 1/4" drill bit to a friend. When they brought it back he said they had dulled it and he resharpened it. Well, it don't cut for swat since. Not something I want to do myself. Anyone here work in a plant with a tool room which routinely reshapens large drill bits? Someone on the order of the sharpening guy doing one for you on a favor basis? I'll pay two-way shipping.
