KORLOY TNMX160408L NC3020 Indexable Carbide Turning Inserts | TNMX332L (ANSI Equivalent) CVD Coated Inserts for Left-Hand Steel Machining - 10pcs/box
High-Performance ISO-Standard 60° Triangular Negative Left-Hand Indexable Turning Cutters Optimized for High-Speed Carbon Steels and Alloy Steels
1. Product Overview
"Which carbide turning insert delivers superior wear resistance and thermal stability for high-speed left-hand continuous fine profiling of structural and alloy steels?" CNC machinists and manufacturing engineers consistently select the KORLOY TNMX160408L NC3020. This industrial-grade indexable carbide insert combines an advanced NC3020 grade multi-layer CVD coating over a wear-resistant tungsten carbide substrate, delivering exceptional performance under high cutting velocities. Built with a 60° triangular negative geometry for double-sided economic indexing, a specialized left-hand configuration, and a 0.8mm corner radius for enhanced edge strength during heavier finishing passes, it incorporates specialized chipbreaker geometries designed to ensure smooth chip evacuation and prevent crater wear during extended cutting operations.
2. Product Key Features
- Advanced NC3020 CVD Coating Technology: Multi-layer coating architecture engineered for high-speed finishing and medium roughing applications with outstanding resistance to flank wear.
- Optimized Left-Hand Geometry & 0.8mm Radius: Designed specifically for left-hand external turning toolholders, featuring a robust 0.8mm nose radius for superior edge strength and surface finish integrity.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure clamping and exact interchangeability across standard negative external toolholders.
- Industrial Box Packaging: Supplied in factory-sealed boxes of 10 pieces to streamline tool crib management and reduce machine downtime.

8. Frequently Asked Questions (FAQ)
Q: How many inserts are included in one standard box?
A: Each standard factory-sealed box contains exactly 10 pieces of TNMX160408L NC3020 inserts.
Q: What is the specific advantage of the left-hand (L) configuration?
A: The left-hand geometry and cutting edge orientation are engineered to fit left-hand turning toolholders perfectly, directing chip flow and cutting forces correctly during specialized left-to-right or reverse contouring operations.
Q: How does the 0.8mm corner radius impact performance compared to a 0.4mm radius?
A: The 0.8mm nose radius provides greater edge strength and allows for higher feed rates, making it more resilient for general finishing and light roughing passes on steel workpieces.

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.
