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) |

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:

- 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.
