Korloy SP200 NC3030 2mm Single-Ended Parting Insert for Interrupted Cuts (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SP200 NC3030 is a specialized 2.0mm Single-Ended Parting and Grooving Insert engineered for maximum impact resistance. While other inserts might fail under vibration or interrupted cuts, the NC3030 High-Toughness Grade is built to absorb mechanical shock. This 2mm single-ended insert is the premier choice for parting off hexagonal bars, components with keyways, or whenever your machining setup lacks perfect rigidity.
The Toughness Specialist: NC3030 is Korloy's most durable CVD grade for steel. It features a unique substrate that prevents crack propagation, making the SP200 NC3030 ideal for "scaly" surfaces and heavy-duty manual or CNC lathes with less-than-perfect stability.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Insert Style | Single-Ended (Maximum Rigidity) |
| Cutting Width (W) | 2.0 mm |
| Grade | NC3030 (Ultra-Tough CVD Coating) |
| Application | Interrupted Parting, Raw Surfaces |
Core Performance Benefits:
- Anti-Chipping Substrate: The specialized NC3030 matrix is designed to withstand the violent "in-and-out" forces of interrupted parting.
- Shock-Resistant Coating: Thick CVD layers provide a shield against both thermal shock and mechanical impact.
- 2.0mm Slim Profile: Minimizes expensive material loss while providing the strength of a single-ended seating design.
- Excellent Chip Management: Even in tough, scaly materials, the SP chipbreaker ensures chips are narrow and curled for easy exit.
Recommended Cutting Parameters (Steel / Interrupted):
| Condition | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Carbon Steel (Interrupted) | 80 - 160 m/min | 0.04 - 0.12 mm/rev |
| Alloy Steel (Rough Surface) | 60 - 130 m/min | 0.03 - 0.10 mm/rev |
| Manual Lathe / Unstable | 50 - 100 m/min | 0.03 - 0.08 mm/rev |
Compatible Tool Holders:
For maximum shock absorption, use with these standard 2mm systems:
- Parting Blades: SPB 26-2 / SPB 32-2
- Blade Blocks: SMBB 1626 / 2026 / 2526
Machinist Tip: The "NC3030 Safety Net"
When should you switch from NC3020 to NC3030?
The Problem Solver. Switch to NC3030 if your SP200 tips are "snapping" or showing micro-cracks. It is slightly slower but much harder to break, especially during the impact of parting off hexagonal or non-round stock.
The High Producer. Use NC3020 for continuous, high-speed parting of round bars in stable CNC machines. It offers better wear resistance but is more brittle than NC3030.
Pro Advice: If you're cutting off a part and the machine starts to "sing" (high-pitched vibration), NC3030 is your best defense against the insert shattering due to that resonance.
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.
