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) |

- 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.
