The Original Korloy CCMT060208-HMP NC3020 is a high-strength turning insert designed for carbon steel and alloy steel. Featuring a robust R0.8 nose radius and the specialized HMP chipbreaker, it provides the maximum edge stability required for heavy-duty semi-finishing and interrupted cuts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT060208-HMP |
| Grade | NC3020 (CVD Coated for Steel) |
| Nose Radius | 0.8 mm (Maximum Edge Strength) |
| Chipbreaker | HMP (High Strength & General Purpose) |
Core Performance Benefits:
- Maximum Edge Stability: The 0.8mm radius offers superior resistance to chipping and notch wear, ideal for rougher surfaces or interrupted machining.
- High Metal Removal Rate: Allows for higher feed rates compared to R0.2/R0.4 models, significantly reducing cycle times.
- Superior CVD Coating: NC3020 grade is engineered for high thermal stability and consistent wear resistance in carbon and alloy steels.
- Effective Chip Control: The HMP geometry breaks chips efficiently at larger depths of cut, preventing long, stringy chips.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (HB180-280) | 200 - 380 m/min | 0.15 - 0.40 mm/rev | 0.8 - 3.5 mm |
| Alloy Steel (HB280-350) | 150 - 300 m/min | 0.12 - 0.35 mm/rev | 0.8 - 3.0 mm |
Compatible Tool Holders:

Packaging: 10 pieces per box.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
