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

I've seen the term "tungsten carbide steel" before and the products turned out to be mostly high speed steel with (maybe) some tungsten in the alloy so I was skeptical when I saw the title of this one list . Haven't used these end mills yet so can't comment on how well they work, but their extremely high density (very heavy for their size) leaves no doubt that it is indeed tungsten carbide!
