The Original Korloy MGMN200-02-R NC3030 is a high-productivity 2.0mm Right-Hand Profiling and Grooving Insert. Engineered specifically for Steel (P) applications, this insert features the advanced NC3030 CVD coating, which offers exceptional hardness and wear resistance at high temperatures. With its sharp 0.2mm corner radius (R0.2) and optimized chipbreaker, it is the ideal solution for high-volume production of steel shafts, fasteners, and automotive components where tool life consistency is critical.
The Mass Production Specialist: Unlike PVD-coated universal inserts, the NC3030 CVD grade is built to thrive in high-speed environments. It provides a significant boost in tool life when machining carbon and alloy steels in stable setups, making it the most cost-effective choice for long-run jobs.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | MGMN200-02-R |
| Width / Radius | 2.0 mm / R0.2 |

Production Insight: NC3030 vs. PC5300
When machining steel, choosing the right coating technology is key to profitability:
The Efficiency King. Thicker coating for high-speed stability. Best for continuous cuts and mass production in steel. It lasts significantly longer than PVD when heat is a factor.
The Universal Protector. Thinner, sharper coating. Best for interrupted cuts, small batches, or stainless steel where toughness is more important than pure wear resistance.
Machinist's Pro Tip: For MGMN200-02-R NC3030, ensure you have a stable setup. CVD grades are harder but slightly more brittle than PVD. If your part is rigid and the spindle is true, you can increase your cutting speed by 20-30% compared to standard PVD inserts.
Packaging: 10 pieces per box.
