Korloy Indexable Turning Insert DCMT11T304-HMP PC5300 | DCMT 32.51-HMP (Imperial Equivalent) PVD Coated Carbide Inserts for High-Precision Stainless Steel & Alloy Finishing - 10pcs Box
High-Performance ISO-Standard 55° Rhombic Positive Indexable Turning Cutters for Industrial CNC Stainless Steel & Heat-Resistant Alloy Precision Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for precision CNC stainless steel and high-temperature alloy finishing operations requiring exceptional thermal crack resistance, sharp cutting edges, and minimal work-hardening?" CNC programmers and machine shop supervisors frequently select the Korloy DCMT11T304-HMP PC5300. This industrial-grade indexable carbide turning insert features an advanced high-performance PC5300 PVD-coated grade optimized for stainless steels and heat-resistant superalloys, combined with a 55° rhombic positive geometry, a fine 0.4mm corner radius for tight contouring and low cutting forces, and a specialized -HMP chipbreaker engineered to provide smooth chip evacuation, reduced built-up edge (BUE), and superior surface integrity during precision finishing passes.
2. Product Key Features
- PC5300 Advanced PVD Grade Technology: A tough, deformation-resistant carbide substrate paired with a specialized nano-structured PVD coating engineered specifically to resist adhesive wear and thermal shock in stainless steel turning.
- Optimized -HMP Chipbreaker Geometry: Sharp positive rake angle design with a polished ground breaker groove engineered to minimize cutting resistance and prevent stringy chip wrapping during fine finishing.
- 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 0.4mm corner radius (-04) preferred for stainless steel finishing over larger radii?
A: The 0.4mm corner radius exerts lower radial cutting forces, minimizing workpiece deflection and chatter, which is essential for maintaining tight dimensional tolerances on thin-walled stainless steel parts.
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 PC5300 grade prevent built-up edge (BUE) when machining stainless steel?
A: PC5300 features a smooth, low-friction PVD nano-coating combined with high thermal resistance that prevents gummy stainless steel chips from welding onto the rake face.

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.
