I love ground HSS, it's my number one choice for 95% of my lathe work. I take a lot of pride in the art form of grinding, and it is rewarding to run a tool that sings as smooth as a string concerto. I went through a brief period where I set ebay search alerts for blanks and "machinist lots" or estate lots until I had 50 lbs or so of excellent blanks, with lots of premium stuff along with the name brand general purpose tungsten/moly stuff. It's nice to have a variety to suit the work. Anyway, In the end, I was averaging about $3 per blank and passed on lots that were above that. So that's my secret, and I'm stocked up so I don't mind sharing... not worried about competing with y'all for auction lots anymore!

This link is to the best information source on tool steel that I have ever come across, and I am a fanatical reader. I refer to it often. It will help you identify what you're looking at and what it is good for. There are certain alloys and brands of tool blank that are seriously holy grail finds that get mixed in with random lots, and are either expensive or unattainable when they are identified by the seller. One more tool for your toolbox on your journey to learning the most versatile and cost-effective way to tool your lathe.
