Benjamin ★★★★★

Switched from a brazed carbide tool to these T-15 HSS threading inserts and the 60 degree thread angle is cutting cleaner with less chatter. They’re holding an edge well in 4140 steel so far, definitely worth the price for the convenience of indexable threading.

Claire ★★★★★

Cutting threads on stainless was giving me trouble until I tried these T-15 HSS inserts; they held their edge noticeably longer than the carbide I had been using. The 60-degree thread angle cut cleanly on the first pass, and the indexable design means I can just flip the insert instead of stopping t

William H. ★★★★★

The 60-degree thread angle on these T-15 HSS inserts cleaned up my cuts immediately, and they've held up through several hundred threads without any dulling. I'm impressed by how smoothly they index into the holder compared to other carbide options I've tried.
