Review on 🔧 Carbide Turning Chipbreaker 32/52 – Optimize Your Search! by Brock Chisholm

I installed one of these on my small lathe and made some test cuts on several materials. It worked great on plastic (Delrin and PVC), aluminum (6061), brass (probably 260), mild steel (1081, 12L15, annealed O1 boring bar) and stainless steel (brand unknown). I tried several hardened materials and found the performance far from pleasant. The shavings on the 6061 are long and fibrous, but that's not unique to this insert. seems to be fairly common on 6061. In general. It is in order. They don't match what is shown in the picture and there is no chip breaker, but they work fine. What can you say? it's a steep threaded insert that costs $2.50. This is not good for hardened materials, but good for light work.
