MGEHR2020-2 External Grooving and Parting Tool Holder

The MGEHR2020-2 is a reliable external grooving and parting tool holder designed for CNC and conventional lathes. With its 20×20 mm shank, it provides stability and precision for parting-off, slotting, and grooving applications. It is specifically made to fit MGMN 2.0 mm carbide inserts, allowing accurate narrow grooves and efficient parting with minimal material loss.

The -2 designation indicates compatibility with 2.0 mm insert width, making it suitable for light to medium-duty operations. Its secure clamping system ensures proper insert positioning, reduces vibration, and promotes efficient chip evacuation. This results in improved surface finish, longer insert life, and stable machining performance.

The MGEHR2020-2 is widely applied in automotive, aerospace, and general machining industries where reliable parting and grooving are required. When used with MGMN200 inserts, it provides consistent results across steels, stainless steels, and cast irons.
