BEYOND MCGNR / MCGNL External Turning Toolholders
The BEYOND MCGNR/MCGNL series is designed for external turning applications using CNMG carbide inserts. Featuring an M-type clamp-and-lock pin system, these toolholders provide excellent insert stability, rigidity, and repeatability for medium to heavy machining. The third letter G in the ISO code indicates a 90° approach angle, making it ideal for general turning on steel, stainless steel, cast iron, and alloy materials.

- Clamping Method: M-type (Clamp + Lock Pin)
- Compatible Inserts: CNMG + size code
- Approach Angle: 90° (ISO letter G)
- Hand of Tool: Right-hand (R) / Left-hand (L)
- High rigidity for stable cutting at medium to high feed rates
