Review on High-Performance Carbide Tungsten Flutes Milling Straight: Precision Cutting Tool for Superior Results by Junrey Jewel

I was expecting HSS to have some sort of carbide-like coating, but it's actually solid TC. I don't do any serious work with them, I just work with a cross vise on a large mild steel and carbon steel drill press, but overall these things still make good chips. I have no idea how they will perform in a real grinder, but if this drill press setup indicates they should cut like butter.
