Korloy MGMN150-G NC3030 1.5mm Double-Ended Tough Grooving Insert for Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy MGMN150-G NC3030 is a specialized 1.5mm Double-Ended Grooving Insert engineered for Toughness and Reliability. While 1.5mm inserts are often fragile, the combination of the reinforced -G (General) chipbreaker and the NC3030 CVD coating makes this insert a powerhouse for difficult steel applications. It is specifically designed to handle interrupted cuts, unstable setups, and rough surfaces in Carbon and Alloy Steels where standard inserts might chip or fail.
Built for the Real World: NC3030 is Korloy’s most impact-resistant CVD grade for steel. If your CNC process involves grooving hex bars, parts with cross-holes, or heavy-duty parting through scale, the MGMN150-G NC3030 provides the "safety net" you need.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN150-G |
| Insert Width (w) | 1.5 mm |
| Grade | NC3030 (High-Toughness CVD) |
| Chipbreaker | -G (Reinforced Edge) |
Core Performance Benefits:
- Shock Absorption: The specialized substrate of NC3030 prevents cracks from propagating, making it ideal for non-continuous cuts.
- Double-Ended Economy: Two cutting edges per insert reduce tool change frequency and maximize your investment.
- 1.5mm Narrow Kerf: Minimizes material waste during parting and reduces spindle load on small-capacity CNC machines.
- Optimized Chip Control: The -G geometry forces chips to curl tightly, ensuring they exit 1.5mm narrow grooves without scratching the side walls.
Recommended Cutting Parameters:
| Condition | Cutting Speed (Vc) | Feed Rate (f) |
|---|---|---|
| Steel (Continuous) | 100 - 180 m/min | 0.03 - 0.08 mm/rev |
| Steel (Interrupted) | 70 - 140 m/min | 0.03 - 0.06 mm/rev |
| Cast Iron | 80 - 160 m/min | 0.04 - 0.09 mm/rev |
Compatible Tool Holders:
Pairs with specialized 1.5mm width MGEHR holders for maximum support:
- External Holders: MGEHR 1010-1.5 / 1212-1.5 / 1616-1.5
Steel Grade Selection: NC3030 vs. NC3020
In narrow 1.5mm grooving, choosing the wrong grade often leads to catastrophic breakage:
The Toughness Champion. Designed for durability. Best for interrupted cuts, low speeds, and less stable machines. Protects the 1.5mm tip from snapping.
The Efficiency Specialist. Best for high-speed, continuous production. Offers better wear resistance but is more susceptible to chipping if the cut is unstable.
Machinist's Pro Tip: For the MGMN150-G, rigidity is your best friend. Even with the tough NC3030 grade, ensure your tool overhang is as short as possible. For parting-off, always stop the feed 0.5mm before the center to allow the part to drop cleanly.
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.
