Korloy SP500 PC9030 5mm Single-Ended Stainless Steel Parting Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SP500 PC9030 is a specialized 5.0mm Single-Ended Parting and Grooving Insert designed for extra-large workpieces and challenging materials. Engineered for Stainless Steel (M-Group) and Heat-Resistant Super Alloys (S-Group), the PC9030 Grade combines a sharp micro-geometry with a high-performance PVD coating. This 5.0mm insert offers the massive rigidity required to prevent tool deflection when parting off large-diameter solid stainless bars or roughing out wide grooves.
Heavy-Duty Precision: Large-diameter stainless steel parting generates immense heat and pressure. The SP500 PC9030 is built to handle these extremes, utilizing a TiAlN-based PVD coating that resists thermal cracking and prevents gummy chips from welding to the edge.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Cutting Width (W) | 5.0 mm (+/- 0.05mm) |
| Grade | PC9030 (Premium PVD for Stainless) |
| Design | Single-Ended (Maximum Tool Life) |
| Ideal For | Deep Grooving, Large Shaft Parting, Tough Forgings |
Core Performance Benefits:
- Extreme Radial Rigidity: The 5mm width ensures the insert remains stable even during deep plunging into high-strength alloys.
- Thermal Shock Resistance: The PVD coating is optimized for the intermittent cooling cycles common in heavy-duty CNC turning.
- Anti-BUE Technology: Prevents Built-Up Edge, which is crucial for maintaining dimensional accuracy in 300-series stainless.
- Optimized Chip Breaking: Specifically tuned for 5mm wide chips, ensuring they are compressed and ejected efficiently from deep radial slots.
Recommended Cutting Parameters (Stainless & Alloys):
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Austenitic (304, 316) | 70 - 130 m/min | 0.08 - 0.22 mm/rev |
| Duplex Stainless Steel | 50 - 90 m/min | 0.06 - 0.18 mm/rev |
| Heat Resistant (Inconel/Monel) | 20 - 50 m/min | 0.05 - 0.12 mm/rev |
Compatible Heavy-Duty Tool Holders:
For safe 5.0mm operation, use high-rigidity blades and holders:
- Heavy Duty Blades: SPB 32-5 / SPB 45-5
- Integral Parting Shank: NCIH 32-5 / NCIH 25-5
- Support Blocks: SMBB 2532 / 3232 Series
Machinist Tip: Why choose SP500 PC9030?
Optimizing massive parting tasks in stainless steel:
Edge Sharpness. Because stainless is "gummy," it needs a sharp edge to shear the material. PC9030's PVD coating allows for a much sharper edge than CVD steel grades (like NC3120), reducing the "pushing" force and heat build-up.
Stability is King. If your 3mm inserts are snapping during deep cuts in large stainless shafts, the 5mm SP500 provides the necessary cross-sectional strength to resist twisting and vibration.
Pro Advice: Always ensure your coolant flow is generous. For 5mm parting, a "flood" of coolant is necessary to prevent the material from work-hardening and to help flush out the massive chips.
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.
