I'm trying to drill and tap my existing SG-34 toolholders to accept bushings on the back (subspindle) end for holding a pair of drills... the pilot drill penetrated through the casing, which I'm guessing is about a 1/16" of an inch, but my twist drill just spins in place and won't go through.
Has anyone modified their Hardinge SG (Conquest T42) toolholders, and if so, does the hardening go all the way through or is it just at the surface?
While you're reading this, if you have any SG-30 or SG-46 toolholders you could part with, I'd buy them :-)
