Korloy MGMN300-02-R NC3030 3mm R0.2 Right-Hand Steel Grooving Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN300-02-R NC3030 is a high-productivity 3.0mm Right-Hand Profiling and Grooving Insert. Specifically engineered for Steel (P) mass production, this insert features the thick-film NC3030 CVD coating. This technology provides an exceptional thermal barrier, allowing for higher cutting speeds and significantly longer tool life compared to standard PVD inserts. With a sharp 0.2mm corner radius (R0.2) and a specialized chipbreaker, it ensures precise profiling and excellent surface finishes on a wide variety of steel workpieces.
The Steel Efficiency Master: The NC3030 grade is optimized for continuous cutting at elevated temperatures. If your goal is to reduce cycle times and minimize insert changes during long-run steel machining, this CVD-coated 3.0mm insert is your best investment.
Technical Specifications:

Core Performance Benefits:
- Extreme Heat Resistance: The CVD coating acts as a shield, maintaining edge hardness even during high-velocity cutting.
- Mass Production Stability: Highly consistent wear patterns make it easy to predict tool changes in automated CNC environments.
- Precision Profiling: The R0.2 radius and -R direction are perfect for specific profiling paths and finishing of narrow grooves.
- Crater Wear Protection: Specifically designed to resist the chemical wear typical of high-speed steel turning.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|

| Alloy Steel (4140 / 42CrMo) | 110 - 200 m/min | 0.05 - 0.14 mm/rev |
| Cast Steel | 90 - 160 m/min | 0.07 - 0.18 mm/rev |
Compatible Tool Holders:
Fits all standard 3.0mm seat grooving systems. We recommend high-rigidity bars for NC3030 performance:
- External Holders: MGEHR 2020-3 / 2525-3 / 3232-3
- Internal Holders: MGIVR 2520-3 / 3125-3
Pro Tip: Why NC3030 (CVD) for 3.0mm Grooving?
Understanding when to switch from PVD to CVD can save you thousands in tooling costs:
The Speed Demon. Best for continuous machining of steel at high surface speeds. The thick coating thrives under heat but is less suited for heavy interruptions.
The Tough All-Rounder. Thinner, tougher coating. Superior for small batches, stainless steel, or when the cut is interrupted (e.g., cross holes).
Machinist's Pro Tip: For MGMN300-02-R NC3030, if you notice built-up edge, *increase* your cutting speed. CVD grades perform better when they reach their optimal operating temperature, which helps the chip slide over the coating more smoothly.
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.
