So someone had a "Lot of old HSS tool bits" for sale. No picture, approx 30lbs. $50. I mean, why wouldn't you just buy that? Sooooo, I did. And it got here... Some of this I'm familiar with, but this was NOT what I was expecting Little help here, what the heck did I get? Normal stuff first. It gets weirder as it goes...
Edit: Identified stuff
Cleveland Twist Drill MoMax /Super MoMax Cobalt: MoMax Cobalt seem to be an M30, Super MoMax is an M42
Latrobe Crusader: M3-2 "unusual combination of extremely high edge strength at high hardness levels"
Stellite: this stuff is the devil in my industry. I think it's actually outlawed. Makes wicked awesome valve seats
VR/Wesson Tantung G: Some kind of chromium, tungsten, columbium and carbon in a cobalt matrix. Not a HSS or Carbide. Probably alien technology similar to Stellite
BASCo Congo: Braeburn Alloy Steel Corp. Congo is an M6, for higher speeds/feeds
(Crucible) Rex 49: M41 ultra-hard "high-speed tool steel designed to give much longer life in machining difficult to cut metals such as highly-alloyed steels, stainless steels, superalloys, and titanium"
Hakansson 530-1: ?????? Can't find anything on this at all
