Korloy FGD300R-03 PC9030 3mm Single-Ended Grooving Insert for Stainless Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy FGD300R-03 PC9030 is a high-precision Single-Ended Parting and Grooving Insert specifically optimized for Stainless Steel and High-Temperature Alloys. The 3.0mm cutting width provides excellent rigidity while minimizing material waste. Unlike double-ended inserts, the single-ended FGD design offers a superior seating structure, significantly reducing vibration during deep grooving and parting-off. Utilizing the PC9030 PVD coating, this insert features an ultra-sharp cutting edge and high resistance to built-up edge (BUE), ensuring a premium surface finish.
Stainless Steel Specialist: PC9030 is Korloy’s leading grade for gummy materials. When machining 304 or 316 stainless, this insert prevents chip welding and maintains a sharp edge far longer than standard CVD grades.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | FGD300R-03 |
| Insert Design | Single-Ended (Precision Stability) |
| Width (w) | 3.0 mm |

Core Performance Benefits:
- Maximum Clamping Stability: The single-ended long-body design provides a secure seat, essential for maintaining precision in deep grooving.
- PVD PC9030 Coating: Fine-grained substrate with high oxidation resistance, ideal for cutting tough alloys and stainless steel at medium speeds.
- Sharp Geometry: The R0.3 corner radius and FGD chipbreaker combine to produce narrow, manageable chips that won't scratch the groove walls.
- Superior Surface Finish: Engineered to minimize friction and cutting force, delivering a mirror-like finish on the workpiece.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |

Grade Strategy: PC9030 vs. NC3030
Choosing the right coating for your 3mm FGD insert is critical for tool life:
Best for Stainless Steel and Tough Alloys. It has a sharper edge and superior resistance to built-up edge. Essential for precision work in gummy materials.
Best for General Steels. This grade is optimized for high-speed cutting in carbon and alloy steels, offering higher thermal stability than PVD.
Machinist's Pro Tip: When parting off stainless steel tubing with the FGD300R PC9030, ensure you use a constant surface speed (CSS) program. This keeps the Vc optimal as the tool moves toward the center, preventing the material from work-hardening.
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.
