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:
- External Turning: SCLCR0808F06 / SCLCR1010H06 / SCLCR1212H06
- Boring Bars (Internal): S10K-SCLCR06 / S12M-SCLCR06
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:
- 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.
- 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.
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.
