Description

The Original Korloy CCMT09T308-HMP NC3030 is a heavy-duty turning insert designed for maximum reliability in tough steel applications. Combining a robust 0.8mm nose radius with the ultra-tough NC3030 grade, this insert excels at high-feed rates and interrupted cuts where standard inserts might fail or chip.

Technical Specifications:

Brand Korloy (100% Genuine)
ISO Code CCMT09T308-HMP
Grade NC3030 (High Toughness CVD)
Nose Radius 0.8 mm (Maximum Edge Strength)
Best For Interrupted Cuts, Rough Surfaces, High Feed

Core Performance Benefits:

  • Shock Resistance: The NC3030 grade features a specialized substrate that absorbs mechanical shock, making it the top choice for parts with holes, slots, or irregular shapes.
  • Maximum Edge Strength: The R0.8 radius provides a larger contact area, distributing cutting forces to prevent edge collapse under heavy loads.
  • Optimized HMP Chipbreaker: Engineered to manage thick chips at higher feed rates, ensuring smooth chip evacuation during roughing.
  • Reliable in Unstable Setups: Excellent for use in older CNC machines or when machining workpieces with significant overhang.

Recommended Cutting Parameters:

Workpiece Material Cutting Speed (Vc) Feed Rate (f) Depth of Cut (ap)
Carbon Steel (HB180-280) 120 - 260 m/min 0.15 - 0.45 mm/rev 0.8 - 4.5 mm
Alloy Steel (HB280-350) 100 - 200 m/min 0.12 - 0.40 mm/rev 0.8 - 4.0 mm
