The Original Korloy MGMN150-G NC3120 is a versatile 1.5mm Double-Ended Grooving Insert designed for General Purpose Steel Machining. When your production requires a balance between high wear resistance and edge toughness, the NC3120 grade is the ideal choice. The 1.5mm narrow width minimizes material waste, making it perfect for precision parting-off and narrow grooving in Carbon Steel, Alloy Steel, and Cast Iron. Featuring the reinforced -G chipbreaker, this insert ensures stable chip control even in varied cutting depths.
The Universal Choice: NC3120 is engineered for versatility. It performs exceptionally well across a wide range of cutting speeds, making it the "go-to" grade for job shops and CNC environments where multiple steel types are processed using the same setup.

Tech Tip: Why choose NC3120 for 1.5mm Grooving?
In narrow grooving, NC3120 acts as the middle ground between high speed and high toughness:
The Generalist. Best for shops machining various steel grades. It is more forgiving than NC3020 if the cutting speed fluctuates.
NC3020 is for Pure Speed in stable runs. NC3030 is for Heavy Impact and interrupted cuts. NC3120 sits perfectly in between.
Machinist's Pro Tip: For 1.5mm narrow parting, ensure your tool is set exactly to the center height. Even 0.1mm deviation can lead to premature tip wear or a "pip" left on the workpiece when using universal grades like NC3120.
Packaging: 10 pieces per box.
