The Original Korloy MGMN150-M NC3020 is a specialized 1.5mm Double-Ended Grooving Insert engineered for high-precision narrow grooving and parting operations. This insert is part of Korloy’s flagship MGEHR system, featuring the NC3020 high-speed CVD grade. It is designed specifically for Steel (P) machining where high spindle speeds and thermal stability are required. The 1.5mm width is ideal for miniature components and applications where material conservation is critical.
High-Efficiency Narrow Grooving: The MGMN150-M combines a narrow 1.5mm profile with a double-ended design, offering twice the tool life per insert. The -M (Medium) chipbreaker provides excellent chip control, preventing the "long stringy chips" common in narrow grooving tasks.
Technical Specifications:

Core Performance Benefits:
- Precision Parting: The narrow 1.5mm kerf reduces material waste and cutting forces, perfect for small-diameter bars.
- NC3020 Thermal Shield: The premium CVD coating allows for higher Vc (cutting speed), making it the "efficiency king" for stable steel production.
- Double-Edge Economy: Two cutting edges per insert reduce tooling costs by 50% compared to single-ended designs.
- Excellent Surface Integrity: The -M chipbreaker ensures chips are broken away from the groove walls, preventing scratches on the workpiece.
Recommended Cutting Parameters:
| Material | Cutting Speed (Vc) | Feed Rate (f) |

| Alloy Steel | 100 - 180 m/min | 0.03 - 0.07 mm/rev |
| Tool Steel | 80 - 150 m/min | 0.02 - 0.06 mm/rev |
Compatible Tool Holders:
Must be used with dedicated 1.5mm MGEHR/L tool holders:
- External Holders: MGEHR 1010-1.5 / 1212-1.5 / 1616-1.5
Strategic Tip: NC3020 vs. NC3030
For 1.5mm narrow grooving, choosing the right grade is critical to prevent tool breakage:
Best for Continuous Cutting. Use this for stable setups and high-speed production. It offers superior wear resistance and maintains edge sharpness longer.
Best for Interrupted Cutting. If you are grooving hex bars or parts with holes, the NC3030 provides the necessary toughness to prevent edge chipping.
Machinist's Pro Tip: Narrow inserts like the MGMN150 are sensitive to feed rates. Because the blade is only 1.5mm wide, always start at the lower end of the recommended feed rate (0.03 mm/rev) to ensure stable chip formation before increasing speed.
Packaging: 10 pieces per box.
