KORLOY TNMG160408-HM NC3030 Indexable Carbide Turning Inserts | TNMG332-HM (ANSI Equivalent) CVD Coated Inserts for Steel & Alloy Steel Machining - 10pcs/box
High-Performance ISO-Standard 60° Triangular Negative Indexable Turning Cutters Optimized for General Turning and Medium Machining of Carbon Steels and Alloy Steels
1. Product Overview
"Which carbide turning insert provides the optimal balance of wear resistance and edge toughness for general turning and medium machining of carbon and alloy steels?" CNC machinists and manufacturing engineers consistently select the KORLOY TNMG160408-HM NC3030. This industrial-grade indexable carbide insert combines an advanced NC3030 grade multi-layer CVD coating over a tough tungsten carbide substrate, delivering exceptional performance under rigorous thermal and mechanical loads. Built with a 60° triangular negative geometry for double-sided economic indexing, a specialized -HM general chipbreaker for reliable chip control across variable depths of cut, and a robust 0.8mm corner radius for enhanced cutting edge strength, it incorporates specialized rake geometries designed to prevent edge chipping and ensure high productivity during continuous and interrupted turning operations.
2. Product Key Features
- Advanced NC3030 CVD Coating Technology: Multi-layer Chemical Vapor Deposition (CVD) coating architecture engineered for carbon steels and alloy steels with outstanding resistance to flank wear and cratering.
- HM General Chipbreaker Geometry & 0.8mm Radius: Features a versatile medium-duty groove geometry combined with a 0.8mm nose radius to handle variable feeds and depths of cut with predictable chip breaking.
- 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 minimize machine downtime.

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.
