The Original Korloy CCMT120404-HMP NC3030 is a high-reliability turning insert designed for steel finishing in challenging conditions. As a robust size-12 insert, it provides excellent stability, while the NC3030 grade offers the necessary toughness to withstand interrupted cuts and vibration that would chip standard inserts.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT120404-HMP |
| Grade | NC3030 (High Toughness CVD) |
| Nose Radius | 0.4 mm (Precision Finishing) |
| Ideal For | Interrupted Steel Finishing, Unstable Setups |
Core Performance Benefits:
- Superior Edge Security: The NC3030 grade is engineered to prevent edge chipping, making it perfect for machining parts with cross-holes, splines, or irregular shapes.
- Large Format Stability: The CCMT 12 thickness provides better heat dissipation and mechanical strength compared to smaller 06 or 09 sizes.
- HMP Chipbreaker: Delivers excellent chip control at light to medium depths of cut, ensuring high-quality surface finishes on steel workpieces.
- Shock Absorption: Optimized for low-to-medium cutting speeds where toughness is the primary requirement.
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 - 3.0 mm |
| Alloy Steel (HB280-350) | 100 - 220 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.5 mm |
Compatible Tool Holders:
To maximize rigidity, pair this CCMT 12 insert with standard SCLCR/L type holders (Size 12):
- External Turning: SCLCR1616H12 / SCLCR2020K12 / SCLCR2525M12
- Boring Bars (Internal): S16Q-SCLCR12 / S20R-SCLCR12 / S25S-SCLCR12
Quick Guide: NC3020 vs. NC3030
Choosing the right grade for your steel job:
- Best for: Stable, high-speed continuous cutting.
- Focus: Max productivity and tool life.
- Best for: Interrupted cuts and vibration issues.
- Focus: Preventing edge chipping and breakage.
Pro Tip: Use NC3030 when your workpiece has a rough surface or your machine setup lacks rigidity.
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.
