Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SP500 NC3030 is the most robust 5.0mm Single-Ended Parting and Grooving Insert in the SP series. Specifically engineered for Extra-Large Diameter steel bars and the most demanding Heavy-Duty Applications, the NC3030 Grade offers unparalleled toughness. If you are struggling with tool breakage on large-scale CNC lathes or dealing with high-frequency interruptions in tough alloy steels, the SP500 NC3030 is your ultimate solution for process security.
Built for the Extremes: The 5.0mm width combined with a single-ended design provides a massive foundation that prevents insert deflection during deep radial plunging. NC3030 is the most impact-resistant CVD grade, making it nearly "bulletproof" against chipping and shattering in unstable conditions.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Model Code | SP500 |
| Cutting Width (W) | 5.0 mm (+/- 0.1mm) |
| Grade | NC3030 (Maximum Impact Resistance) |
| Coating | Thick Al2O3 + TiCN CVD Layer |
Core Performance Benefits:
- Maximum Edge Integrity: The 5mm profile handles enormous radial forces without snapping, ideal for parting off solid bars over 100mm in diameter.
- Superior Anti-Chipping: NC3030 substrate is optimized to absorb vibration and survive heavy interruptions, even in scaly or oxidized material.
- Aggressive Chip Control: Specialized chipbreaker geometry handles the massive 5mm wide chips, curling them tightly to prevent "bird-nesting" in deep grooves.
- Process Reliability: Reduces machine downtime by providing a predictable and stable tool life in unpredictable cutting environments.
Recommended Cutting Parameters (Heavy Duty):
| Condition | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Large Carbon Steel Bars | 80 - 150 m/min | 0.12 - 0.28 mm/rev |
| Heavy Alloy Steel (Interrupted) | 60 - 110 m/min | 0.10 - 0.22 mm/rev |
| Deep Slotting / Roughing | 50 - 100 m/min | 0.08 - 0.18 mm/rev |
Compatible Tool Holders:
Must be paired with high-capacity heavy-duty parting systems:
- Extra-Large Blades: SPB 32-5 / SPB 45-5 Heavy Duty Blades
- Rigid Tool Blocks: SMBB 3232 / 4032 Heavy Blocks
Machinist Tip: Why SP500 NC3030 is the "Rescue" Insert
When standard 3mm or 4mm inserts keep failing:
Safety First. 5mm parting generates massive heat and force. NC3030 is designed to prevent the tip from "exploding" during the cut, which is critical when machining expensive, large-diameter parts.
High Feed Rate. If you have a brand-new, high-rigidity machine and are cutting standard round bars, NC3020 can handle higher speeds, but it won't survive the impacts that NC3030 can.
Pro Advice: For a 5mm width insert, machine rigidity is non-negotiable. Ensure the blade overhang is minimized to the exact depth needed. If you encounter chatter, NC3030's vibration dampening substrate is your best line of defense.
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.
