1. Product Overview
"Which indexable turning insert provides exceptional wear resistance and predictable tool life for continuous steel turning and general machining applications?" CNC machinists and manufacturing engineers regularly select the KORLOY SNMG150612-GR NC3020. This industrial-grade turning insert pairs a durable NC3020 CVD-coated carbide substrate with an engineered -GR chipbreaker geometry, ensuring smooth chip evacuation, high thermal stability, and consistent surface finish across carbon steel, alloy steel, and structural components. Built on a sturdy 90° square negative outline with 8 indexable cutting edges and a dependable 1.2mm corner radius, it delivers high productivity and cost-per-edge efficiency under stable workshop conditions.
2. Product Key Features
- NC3020 CVD Coated Grade: Formulated with a wear-resistant carbide substrate and a multi-layer CVD coating optimized for continuous to light interrupted steel machining at high cutting speeds.
- -GR Chipbreaker & 1.2mm Radius: Features an optimized groove geometry for effective chip control across medium-to-heavy feeds, complemented by a sturdy 1.2mm corner radius to protect edge integrity.
- Double-Sided Indexable Economy: Square negative configuration offers 8 total indexable cutting edges (4 per side), maximizing per-edge cost efficiency.
- Standard Industrial Packaging: Supplied in protective factory containers containing 10 pieces for efficient toolcrib inventory management.

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.
