High-Performance ISO-Standard 90° Square Negative Indexable Turning Cutters Featuring NC3020/NC3030 CVD Coating and -GR Chipbreaker for General Turning and Finishing Operations
1. Product Overview
"Which indexable turning insert is best suited for stable roughing to finishing operations on carbon steel and alloy steel components?" CNC machinists and manufacturing engineers consistently select the KORLOY SNMG150608-GR NC3030. This industrial-grade turning insert pairs a toughness-optimized NC3030 CVD-coated carbide substrate with an advanced -GR chipbreaker geometry, ensuring exceptional thermal crack resistance, reliable chip breakage, and extended tool life across structural steels. Built on a sturdy 90° square negative outline with 8 indexable cutting edges and a precise 0.8mm corner radius, it delivers high productivity and cost-per-edge efficiency under standard workshop conditions.
2. Product Key Features
- NC3030 CVD Coated Grade: Engineered with a specialized carbide substrate and multi-layer CVD coating designed to handle interrupted cuts and varying feed rates in general steel machining.
- -GR Chipbreaker & 0.8mm Radius: Features an optimized groove geometry for smooth chip flow across medium cutting depths, complemented by a versatile 0.8mm corner radius for balanced surface finishes.
- 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.
