MGHER2020-3 External Grooving and Parting Tool Holder

The MGHER2020-3 is a precision external grooving and parting tool holder designed for CNC and conventional lathes. Built with a 20×20 mm shank, it provides rigidity and stability during machining, ensuring accurate parting and grooving operations. This holder is engineered for MGMN 3.0 mm carbide inserts, making it suitable for medium to heavy-duty cutting.

The designation -3 indicates compatibility with 3.0 mm insert width, which allows stable performance in deeper grooves and parting applications. Its optimized clamping system provides secure insert holding, efficient chip evacuation, and reduced vibration, leading to better surface finish and longer tool life.

The MGHER2020-3 is commonly used in automotive, aerospace, and general machining industries where repeatability and precision are critical. When paired with MGMN300 inserts, it ensures consistent results in steels, stainless steels, and cast irons.
