High-Performance ISO-Standard 55° Diamond Positive Indexable Turning Cutters for Industrial CNC Stainless Steel, Alloy Steel & Exotic Metal Ultra-Precision Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for high-precision CNC stainless steel and alloy steel finishing operations requiring exceptional wear resistance against work hardening, smooth chip evacuation, and tight dimensional tolerance control?" CNC programmers and machine shop supervisors frequently select the Korloy DCMT070202-HMP PC9030. This industrial-grade indexable carbide turning insert features an advanced high-performance PC9030 PVD-coated grade optimized for stainless steels and heat-resistant superalloys, combined with a 55° diamond positive geometry, a fine 0.2mm corner radius for detailed profiling and shallow finishing cuts, and a specialized -HMP chipbreaker engineered to provide excellent chip control at low-to-medium feeds, minimized cutting heat, and superior surface finish integrity.
2. Product Key Features
- PC9030 Advanced PVD Grade Technology: A tough, fine-grained carbide substrate combined with a smooth, wear-resistant PVD coating engineered specifically to resist notch wear, thermal cracking, and chemical adhesion in stainless steel turning.
- Optimized -HMP Chipbreaker Geometry: Positive rake angle design with a specialized ground breaker geometry engineered to prevent stringy chip wrapping and ensure consistent chip fragmentation on ductile materials.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure screw clamping and exact interchangeability across standard positive external turning tool holders and boring bars.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

8. Frequently Asked Questions (FAQ)
Q: Why is the 0.2mm corner radius (-02) optimal for stainless steel finishing passes?
A: The 0.2mm corner radius allows for clean shoulder profiling, precise corner detailing, and reduced cutting pressure, which helps prevent work hardening in austenitic stainless steels.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, individually secured to prevent transit edge damage.
Q: How does PC9030 grade combat built-up edge (BUE) when machining stainless steel?
A: PC9030 utilizes a smooth PVD coating texture that prevents gummy stainless steel chips from welding to the rake face during low-speed finishing cuts.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
