Seems to be a good product at a great price. I've made 60,000 cuts on 4 inch round steel. The chipbreaker works best on heavy cuts. Would like a 1/2" set for my smaller lathe.
Pros
turning inserts with exquisite workmanship, high strength, high toughness, stability and durability. If you need a more suitable insert or turning holder set, you can search for B07G386Y3B (inserts) or B076WTPSVK (holders).
