Kyocera TPMT160308HQ PR1535 – Turning Insert (10 pcs Finishing to Medium, HQ Chipbreaker)
The Kyocera TPMT160308HQ PR1535 is a positive-type triangular turning insert engineered for finishing to medium machining on stainless steel, heat-resistant alloys, and steel. It employs Kyocera’s **PR1535 MEGACOAT NANO** PVD-coated carbide grade, combining strong wear resistance, oxidation stability, and fracture toughness for demanding applications. The **HQ chipbreaker** geometry ensures smooth chip flow, lower cutting forces, and consistent surface finishes under both continuous and mildly interrupted cutting regimes.
