"It's just stainless" .....what i thought too, but after trying 5 new various size HSS drill bits without a dent or single scarf curl result, it's been Undrillum so far, but eventually if I gotta use a laser !!.... tom

I wonder if Jin's heat treated it or its somehow become work hardened? Work hardened SS is the only problem I've had when drilling. I think my oiler will be a faux oiler for the time being.
