Built on Korloy’s advanced NC6315 CVD-coated K-grade platform, this insert delivers exceptional wear resistance, longer tool life, and consistent cutting performance — even under heavy loads or interrupted conditions.
Hook / Attention Line
Tired of frequent insert changes and inconsistent cut quality? Meet the Korloy MGMN150-G NC6315 — engineered for longer tool life, stable performance and lower cost per component.
Key Features & Specs
-
Grade & Coating: NC6315 (K15), with a robust CVD coating (TiCN + Al₂O₃) for exceptional wear- and chipping-resistance.
-
Geometry: Negative-geometry insert (e.g. CNMG / similar styles) with MK (medium) or RK (roughing) chipbreaker options — optimized for both stable medium cuts and heavy, interrupted cast-iron machining.
-
Applications: Primarily for turning cast iron (grey or ductile) — handling high feed, heavy interrupted or continuous cutting with stability.
Why It’s a Best Seller
-
NC6315 is specifically formulated for cast-iron work — delivering much higher resistance to wear, chipping and built-up edge, even under vibrations, heavy depths or unstable clamping.
-
The optimized chipbreaker + insert geometry means consistent surface finish, less scrap, less rework, and fewer tool changes — minimizing downtime.
-
Works reliably across a broad range of cast-iron parts — so you don’t need to keep multiple insert types for different cast-iron grades.
🏭 Application Industries
Ideal for industries working with cast-iron parts: Automotive (engine blocks, brake components), General Engineering, Machinery & Equipment, Heavy-duty Castings, Die & Mould (cast-iron molds), Construction & Agricultural Equipment.

Frequently Asked Questions
NC6315 is designed for machining grey cast iron and ductile cast iron. It performs excellently under high feed, heavy interrupted cuts or continuous turning of cast-iron components.
The CVD coating (TiCN + Al₂O₃) together with optimized chipbreaker geometry gives much higher resistance to wear and chipping, even when machining tough or variable cast-iron materials — resulting in stable tool life and fewer re-breakages.
Yes — with the RK (roughing) chip-breaker version it’s especially suited for heavy interrupted or high-depth-of-cut operations. For medium or continuous cuts, MK (medium) breaker gives stable performance.
Expect fewer insert changes, reduced downtime, consistent surface finish, lower scrap and rework rates, and overall reduced cost per component — particularly on cast-iron parts where inserts often get damaged.
Industries like automotive (engine castings, brake drums), heavy machinery, general engineering, cast-iron piping, pump housings, construction equipment, die & mold for cast components — anywhere cast-iron is being turned, this insert delivers value.
