Product Description:

The GY2M 0400G040N-MM VP20RT Lathe Insert from Mitsubishi Materials is designed for multifunctional grooving applications on automatic and CNC lathes. It offers an excellent combination of wear resistance, edge stability, and chip control, thanks to its optimized MM cutting geometry and VP20RT coating.

It is ideal for combined grooving, parting-off, and light profiling operations, even in demanding materials such as alloy steel, stainless steel, or nodular cast iron.

Technical specifications:

• Model: GY2M 0400G040N-MM

• Grade: VP20RT (multi-function PVD coating)

• Cutting width: 4.00 mm

• Nose radius: 0.40 mm

• Geometry: MM (microfinishing, improved chip control)

• Application: Multifunctional grooving

• Recommended material: Steel, stainless steel, cast iron

• Machine Type: CNC, Automatic, or Conventional Lathe

Key Benefits:

- VP20RT coating: balance between hardness and toughness
- High dimensional accuracy
- MM geometry for improved chip control
- Ideal for versatile and continuous grooving tasks
- Longer tool life and less side wear
