The inside circumference (IC) is 3/8" (0.375") and the thickness is 1/8" (0.125"). There is no chip breaker on this insert.

Emily I. ★★★★★

I've been using these TNMC-32-NV inserts for threading and the 60-degree thread angle makes for clean, precise cuts every time. They're sturdy and seem to hold up well in my steel work.

Eva ★★★★★

The T-15 steel holds an edge way longer than the carbide I’ve tried for small thread work, and the 60-degree angle lines up perfectly with standard threads. I’ve swapped these in and out of the holder a few times now, and they seat solidly every time without any wobble.

Robert ★★★★★

The 60-degree thread angle cut cleanly through stainless steel on my first try, leaving a perfect finish. I've been using these inserts for a few weeks now, and the T-15 HSS holds its edge noticeably longer than the carbide ones I used before. A solid upgrade for my threading jobs.
