Korloy MGMN200-M NC3030 2mm Double-Ended Grooving Insert for Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN200-M NC3030 is a high-toughness 2.0mm Double-Ended Grooving Insert engineered for Steel Machining under Unstable Conditions. When processing standard carbon steels, alloy steels, or forged parts, mechanical shock and vibration are common tool-killers. The NC3030 CVD grade features a thick, heat-resistant coating and a robust substrate designed to absorb impacts, making it the industry benchmark for interrupted cuts and heavy-duty parting-off operations.
Maximum Impact Resistance: Unlike brittle finishing grades, NC3030 is built for "rough" environments. It is the go-to choice for manual lathes with slight spindle play or CNC operations involving cross-holes and hex-bars.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-M |
| Insert Width (w) | 2.0 mm |
| Grade | NC3030 (Heavy-Duty CVD Coated Steel Grade) |
| Chipbreaker | -M (Stable Medium-Cutting Geometry) |
Core Performance Benefits:
- Interrupted Cut Excellence: Superior edge toughness prevents micro-chipping when the tool hits cross-holes or keyways.
- CVD Coating Stability: The multi-layer CVD coating provides an excellent thermal barrier, allowing for stable tool life in dry or wet cutting.
- Double-Ended Reliability: Two usable cutting edges offer excellent cost-efficiency for general-purpose workshop use.
- Secure Chip Control: The -M geometry is designed to narrow the chip for easier evacuation from 2mm grooves, even in softer steels.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Low Carbon Steel (Mild Steel) | 100 - 200 m/min | 0.05 - 0.15 mm/rev |
| Alloy Steel (4140/4340) | 80 - 160 m/min | 0.05 - 0.12 mm/rev |
| Carbon Steel (Medium) | 110 - 180 m/min | 0.06 - 0.15 mm/rev |

The Toughness Guide: NC3030 vs. NC3120
For 2.0mm steel grooving, choosing between these two CVD grades depends on your stability:
The Tough Grade. Best for interrupted cuts, low-speed machining, and old machines. Prioritizes anti-chipping over high-speed wear.
The Balanced Grade. Best for stable CNC operations. Offers higher wear resistance at faster speeds but is more likely to chip during sudden impacts.
Machinist's Pro Tip: If your MGMN200-M NC3030 is wearing out too fast (flank wear), try switching to NC3120. But if your current inserts are "snapping" or "crunching" unexpectedly, NC3030 is the solution to stop the breakage.
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.
