Alexander T. ★★★★★

Finally, a high-speed steel insert that actually fits my holders without slop. The 7° relief cuts clean on my smaller lathe. Much less chipping than the cheap HSS blanks I was grinding myself.

Robert ★★★★★

Swapped out a carbide insert for this HSS one and the finish on my mild steel parts is noticeably smoother. The 7° relief angle seems to help with chip clearance just as advertised.

Alexander ★★★★★

That 80° diamond shape locks into my holder perfectly, and the 7° relief makes facing cuts feel effortless. I've been using it for finishing work on hardened steel, and the edge is holding up better than any carbide I've tried.
