Korloy SP200 PC9030 2mm 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 SP200 PC9030 is a high-performance 2.0mm Single-Ended Parting and Grooving Insert specifically engineered for Stainless Steel (M-Group) and Exotic Alloys (S-Group). Featuring the advanced PC9030 PVD Coating, this insert excels in preventing built-up edges (material welding) common when machining grades like 304, 316, and Duplex. The 2mm width allows for maximum material savings while maintaining enough rigidity for precision parting on Swiss-type and standard CNC lathes.
The Stainless Steel Specialist: PC9030 utilizes an ultra-fine carbide substrate combined with a TiAlN-based PVD coating. This provides the edge sharpness required for gummy materials and the heat resistance needed for work-hardening alloys.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Cutting Width (W) | 2.0 mm (+/- 0.05mm) |
| Grade | PC9030 (PVD Coated for Stainless) |
| Insert Style | Single-Ended (Specialized for Deep Cuts) |
| Target Materials | 304/316 Stainless, Inconel, Titanium |
Core Performance Benefits:
- Anti-Stick Edge: The ultra-smooth PVD surface prevents "chip welding," ensuring a clean cut and preventing premature edge failure.
- High Edge Sharpness: Designed with a positive rake angle to slice through work-hardening stainless steel, reducing cutting pressure and heat.
- Thermal Stability: The nano-structured coating withstands localized high temperatures at the 2mm cutting zone.
- Precise Parting: Minimizes the "burr" or "pip" at the center of the part during final cut-off.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (fn) |
|---|---|---|
| Austenitic (304/316) | 80 - 150 m/min | 0.03 - 0.10 mm/rev |
| Duplex Stainless | 60 - 110 m/min | 0.03 - 0.08 mm/rev |
| Heat Resistant Alloys | 30 - 70 m/min | 0.02 - 0.06 mm/rev |

Machinist Tip: Why choose PC9030?
Selecting the right 2mm insert for your material:
The Stainless Expert. PVD coating is thinner and sharper than CVD. Use this for 300-series stainless, titanium, and any gummy material where precision and surface finish are priority.
The Steel Expert. CVD coatings are thicker and better for high-speed parting of dry or lubricated Carbon Steels. Avoid using these on stainless, as the material will "weld" to the edge.
Pro Advice: When parting off 316 stainless with the SP200, use high-pressure coolant directed exactly at the cutting edge. This flushes the gummy chips and significantly increases the life of your PC9030 insert.
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.
