Also, coated carbide tooling may seem expensive compared to HSS, but it's almost always worth it because the tool will last much longer and tolerate abuse from learning students. I recall a machinist TRYING to destroy a damaged carbide end mill in a demo for students, he had to run the mill full speed, in reverse, with auto-feed on full speed, through a hunk of alloy steel. It chipped the end mill and did some heat damage, and melted some of the alloy steel

Yeah, I've heard that I should expect to pay as much on the tooling as the machine. As for carbide tipped, I learned that lesson with drill bits a couple of years ago. I actually accidentally melted a HSS drill bit tip trying to drill some hardened steel in a drill press. Switched to titanium and that problem was solved.
