The Original Korloy SP600 NC3030 is the ultimate 6.0mm Single-Ended Parting and Grooving Insert for extra-large workpieces. When precision and process security are required for massive steel shafts or heavy-duty industrial components, the NC3030 Grade delivers the highest level of toughness in the Korloy lineup. The 6mm width provides a massive cross-section, effectively eliminating the blade deflection often seen in thinner inserts when performing deep plunging operations.
The Powerhouse of Parting: SP600 NC3030 is engineered for situations where tool failure is not an option. Its single-ended design and 6.0mm edge are built to withstand extreme radial pressure, while the NC3030 substrate acts as a shock absorber against heavy interruptions and machine resonance.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Model Code | SP600 |
| Cutting Width (W) | 6.0 mm (+/- 0.1mm) |
| Grade | NC3030 (Ultra-Tough CVD Coated) |
| Primary Use | Extra-Large Shaft Parting, Heavy-Duty Slitting |
Core Performance Benefits:
- Extreme Tool Rigidity: 6.0mm width allows for extremely deep grooving without the risk of the insert or blade "wandering" or snapping.
- Maximum Fracture Resistance: NC3030 substrate stops crack propagation, making it safe for the roughest forged surfaces and scaly steel.
- Advanced CVD Heat Shield: Thick Al2O3 layer ensures the cutting edge remains stable during the long cycle times required for 6mm wide cuts.
- Heavy-Duty Chip Control: Designed to channel and curl thick chips efficiently, preventing congestion in deep radial slots.
Recommended Cutting Parameters (Extreme Conditions):
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Heavy Carbon Steel Bars | 70 - 140 m/min | 0.15 - 0.35 mm/rev |
| Alloy Steel (Heavy Impact) | 50 - 100 m/min | 0.12 - 0.25 mm/rev |
| Deep Slotting (Over 50mm depth) | 40 - 80 m/min | 0.10 - 0.20 mm/rev |
Compatible Tool Holders:
Must be paired with ultra-rigid 6.0mm parting blocks and blades:
- Heavy-Duty Blades: SPB 32-6 / SPB 45-6 Heavy Duty Blades
- Large Mounting Blocks: SMBB 3232 / 4032 Heavy Duty Series
Machinist Tip: Scaling to SP600
When 4mm or 5mm just isn't enough:
Anti-Snap Protection. A 6mm insert creates massive cutting forces. NC3030 is designed to flex slightly rather than snap under load, protecting your machine spindle and expensive large-diameter workpieces from sudden failure.
Depth Capacity. While SP300 is great for general work, the SP600's body is reinforced to allow much deeper radial plunging (often up to 100mm+ depending on the blade) without chatter or loss of verticality.
Pro Advice: When parting off with SP600, center height is critical. Even a 0.1mm deviation can lead to excessive tool pressure given the 6mm width. Use a dial indicator to set the blade tip perfectly on center.
Packaging: 10 pieces per box.
