Korloy FGM300R-03 NC3030 3mm Multi-Functional Grooving & Side-Turning Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy FGM300R-03 NC3030 is a versatile Multi-Functional Grooving Insert designed for machinists who need to perform grooving, parting, and lateral (side) turning with a single tool. This 3.0mm width insert eliminates the need for tool changes between grooving and profiling operations, significantly reducing cycle times. Featuring the NC3030 CVD coating, it is engineered for high-toughness performance, making it the ideal choice for interrupted cuts and rough surfaces in Carbon and Alloy Steels (P).
The Multi-Function Advantage: Unlike standard grooving inserts, the FGM's geometry is reinforced to handle the side-load forces of lateral turning. This allows you to plunge into a part and then move horizontally to widen the groove or create complex profiles with one tool.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | FGM300R-03 |
| Function | Multi-Functional (Grooving + Side-Turning) |
| Width (w) | 3.0 mm |

- Multi-Functional Holders: FGMR / FGMR 2020-3 / FGMR 2525-3
Knowledge Tip: FGM vs. FGD
Korloy offers different geometries for different tasks. Here’s why FGM is unique:
Built for Versatility. Reinforced sides allow for horizontal turning after plunging. Perfect for complex shapes and reducing the number of tools in your turret.
Built for Deep Parting. While stronger for vertical plunging, it cannot be used for horizontal turning. Best for simple cut-off operations.
Machinist's Pro Tip: When using the FGM300R for side-turning, ensure your depth of cut (Ap) doesn't exceed 2.5mm per pass to maintain stability and prevent vibration. Always use plenty of coolant to evacuate chips from the groove.
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.
