Description

The Original Korloy CCMT060204-HMP NC3030 is a specialized turning insert designed for steel machining under unstable conditions. Featuring the high-toughness NC3030 grade, this insert excels in interrupted cuts and low-to-medium speed operations where edge reliability is paramount.

Technical Specifications:

Brand Korloy (100% Genuine)
ISO Code CCMT060204-HMP
Grade NC3030 (High Toughness CVD)
Nose Radius 0.4 mm (General Purpose)
Primary Application Interrupted Steel Cutting

Core Performance Benefits:

  • Extreme Toughness: The NC3030 grade is specifically formulated to prevent chipping during heavy interrupted cuts or when machining parts with rough surfaces.
  • Edge Reliability: Ideal for older machines or setups with lower rigidity, providing a stable cutting process.
  • Versatile HMP Chipbreaker: Ensures excellent chip evacuation across a wide range of feed rates, reducing heat buildup.
  • CVD Coated Durability: Provides a robust thermal barrier, extending tool life during medium-speed machining of carbon and alloy steels.

Recommended Cutting Parameters:

Workpiece Material Cutting Speed (Vc) Feed Rate (f) Depth of Cut (ap)
Carbon Steel (HB180-280) 120 - 280 m/min 0.10 - 0.25 mm/rev 0.5 - 2.5 mm
Alloy Steel (HB280-350) 100 - 220 m/min 0.08 - 0.20 mm/rev 0.5 - 2.0 mm

Compatible Tool Holders:

To ensure maximum stability, we recommend pairing this CCMT 06 insert with standard SCLCR/L type holders:

Packaging: 10 pieces per box.

 

Quick Guide: NC3020 vs. NC3030

Not sure which grade to choose? Here is a quick breakdown to help you pick the right tool for your steel turning job:

NC3020 (Universal/Wear Resistant)
  • Best for: Continuous cutting & high speeds.
  • Setup: Stable machines and rigid workpiece.
  • Performance: High thermal stability and longer tool life in stable conditions.
  • Target: General steel finishing to semi-finishing.
NC3030 (Tough/Anti-Chipping)
  • Best for: Interrupted cuts (keyways, holes, hex).
  • Setup: Unstable machines, shaky setups, or rough skin.
  • Performance: Exceptional toughness to prevent sudden edge breakage.
  • Target: Heavy roughing or "problematic" steel jobs.

Pro Tip: If your insert is wearing down too fast, switch to NC3020. If your insert is chipping or breaking, switch to NC3030.
