Description

The Original Korloy CCMT09T304-HMP NC3030 is a high-performance turning insert specifically engineered for unstable steel machining conditions. Featuring the high-toughness NC3030 CVD coating, this insert is the industry standard for interrupted cuts, heavy scale removal, and operations where edge security is more critical than pure speed.

Technical Specifications:

Brand Korloy (100% Genuine)
ISO Code CCMT09T304-HMP
Grade NC3030 (High Toughness CVD)
Nose Radius 0.4 mm (Universal Finishing)
Application Interrupted Cuts, Rough Surface Steel

Core Performance Benefits:

  • Exceptional Anti-Chipping: NC3030 is designed with a specialized substrate that absorbs impact, preventing sudden edge breakage during interrupted cuts.
  • Edge Reliability: Ideal for older lathes or shaky setups where vibration is an issue.
  • HMP Chipbreaker: Optimized for versatile chip control across a wide range of feed rates, reducing heat buildup on the cutting edge.
  • Versatile 09T3 Size: Provides excellent stability for medium-sized turning tasks in 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 - 0.30 mm/rev 0.5 - 3.5 mm
Alloy Steel (HB280-350) 100 - 220 m/min 0.08 - 0.25 mm/rev 0.5 - 3.0 mm

Compatible Tool Holders:

For peak stability, pair this insert with standard SCLCR/L type holders (Size 09):

Quick Guide: NC3020 vs. NC3030

Not sure which grade to choose? Here is a quick breakdown:

NC3020 (Wear Resistant)
  • Best for: Continuous cutting & high speeds.
  • Setup: Stable machines and rigid workpiece.
  • Benefit: Longer tool life in consistent steel turning.
NC3030 (Tough Grade)
  • Best for: Interrupted cuts & rough surfaces.
  • Setup: Shaky setups or problematic materials.
  • Benefit: Prevents edge chipping and sudden breakage.

Pro Tip: Use NC3030 (this model) if you encounter frequent edge chipping or are machining parts with keyways/holes.

Packaging: 10 pieces per box.
