Jacob I. ★★★★★

Finally got these for a project that needed clean cuts in hardened steel, and the 11° relief really helps clear chips without binding. They’re holding an edge noticeably longer than the standard carbide inserts I was using before. Exactly what I needed for repeatable precision on my lathe.

Michael ★★★★★

These 11° relief cuts down on chatter significantly compared to the standard inserts I was using, and the T-15 steel holds an edge through a couple dozen pieces of 4140 without any noticeable wear.

Matthew ★★★★★

I’ve been using this T-15 HSS insert for a few days, and the 60° triangle cuts surprisingly clean. The indexing is solid and fast to swap, which saves me time on the lathe.
