Korloy SP300 PC9030 3mm Single-Ended Parting Insert for Stainless Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy SP300 PC9030 is a specialized 3.0mm Single-Ended Parting and Grooving Insert engineered for Stainless Steel (M-Group) and Heat-Resistant Super Alloys (S-Group). By combining an ultra-fine carbide substrate with a high-aluminum PVD coating, the PC9030 Grade offers exceptional edge sharpness and thermal stability. This 3.0mm insert is the industry standard for parting off stainless steel pipes, bars, and complex components where surface finish and dimensional accuracy are critical.
The High-Performance Choice: Unlike standard CVD coatings, the PC9030 PVD coating is thinner and smoother, which prevents gummy stainless steel chips from welding to the cutting edge. This results in longer tool life and significantly better end-face quality on your workpieces.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| Cutting Width (W) | 3.0 mm (+/- 0.05mm) |
| Grade | PC9030 (Premium PVD for Stainless) |
| Design | Single-Ended (Maximum Rigidity) |
| Applications | Parting-off, Deep Grooving, Slotted Components |
Core Performance Benefits:
- Excellent Wear Resistance: The nano-structured PVD coating protects the carbide core from chemical wear during high-temperature stainless cutting.
- Reduced Cutting Force: Optimized rake angles allow the insert to slice through "tough" materials rather than pushing them, reducing machine load.
- Enhanced Surface Finish: The sharp edge and smooth coating combine to eliminate burrs and minimize the "pip" at the center of the part.
- Chip Management: The SP-chipbreaker excels at narrowing the 3mm chip, preventing it from damaging the sidewalls of deep radial slots.
Recommended Cutting Parameters:

Machinist Tip: PC9030 vs. The Rest
Why the SP300 PC9030 is essential for your workshop:
Sharp & Cool. PVD technology allows for a sharper edge compared to CVD steel grades. This is vital for materials that tend to "smear" or work-harden under pressure.
The Steel Heavyweights. These are great for carbon steel, but will often cause "built-up edge" if used on 316 stainless, leading to poor finish and insert breakage.
Pro Advice: When machining 300-series stainless, never stop the feed while the tool is in contact with the material—this will cause instant work-hardening. Keep the feed constant for the best tool life.
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.
