I have Valenite inserts that I have never seen or heard of before I was given these/ thread relief inserts that cut a very nice thread relief and a very good square shoulder at the same time. Very high-grade ground carbide with a 30° taper on the backside of the insert to make a very nice looking smooth thread relief. Never used to cut a thread relief until I was given these inserts.
