Hobby machining - USA HSS >>> asian HSS
I've had my little 7x14 lathe for about a year now, and most of it's shortcomings I can deal with. However, it came with a bunch of cheap tooling that has brought back a lot of things that I used to know, but thought weren't true any more.
Mainly, American high speed steel is much stronger than cheap asian high speed steel. I completely blunted a "HSS" center drill trying to dimple a stainless cocker hammer. I ended up using one of my good American HSS drill bits.
After beating up some asian carbide inserts at various speeds, I finally bought some American HSS inserts. They cut so much better.

I'm a material scientist for an automotive supplier, I sometimes evaluate steels from different suppliers, just because all the materials meet the spec. does not make them equally good, you get what you pay for
