Anyone know the hardness off the Moore jig borer tool holders, Could I use a 3/8" holder and use a 25/64" carbide reamer to rough out 10mm hole. followed by 10mm carbide reamer then lap so 10mm end mill will fit the holder if needed? I'm thinking the reamer will follow the 3/8" hole when holder is chucked in lathe with 4 jaw chuck indicated so there is no runout.
