KORLOY SNMG190616-HS PC9030 Indexable Carbide Turning Inserts | SNMG646-HS (ANSI Equivalent) PVD Coated Inserts for Stainless Steel and Alloy Steel Machining - 10pcs/box
High-Performance ISO-Standard 90° Square Negative Indexable Turning Cutters Featuring PC9030 PVD Coating and HS Chipbreaker for Advanced Stainless Steel Finishing and Medium Machining
1. Product Overview
"Which indexable turning insert provides exceptional wear resistance and thermal shock stability when machining stainless steels and high-temp alloy components?" CNC programmers and manufacturing engineers consistently rely on the KORLOY SNMG190616-HS PC9030. This industrial-grade turning insert pairs a specialized PC9030 PVD-coated carbide grade with an optimized -HS chipbreaker geometry, delivering superior chip control, reduced cutting forces, and extended tool life. Featuring a 90° square negative layout with 8 indexable cutting edges and a precise 1.6mm corner radius, it ensures maximum stability and surface finish quality in demanding production environments.
2. Product Key Features
- PC9030 PVD Coated Grade: Formulated with a tough fine-grain carbide substrate and a high-adhesion PVD coating designed to resist built-up edge (BUE) and thermal cracking in stainless steel.
- HS Chipbreaker & 1.6mm Radius: Features a sharp positive rake face design for low cutting resistance and smooth chip evacuation, backed by a robust 1.6mm corner radius for enhanced edge strength.
- Double-Sided Edge Economy: Square negative design provides 8 total usable indexable cutting edges (4 per side), maximizing cost-per-edge value.
- Standard Industrial Packaging: Supplied in secure factory containers holding 10 pieces for efficient toolcrib management.
