The MWLNR2020M08 is a strong and reliable external turning tool holder designed for CNC and conventional lathe operations. With a square shank size of 20×20 mm and a length of about 125 mm, it provides excellent rigidity and stability under heavy cutting conditions. This holder is designed for WNMG08 carbide inserts, which feature a trigon 80° shape and are commonly used for roughing and finishing operations on steels, stainless steels, and cast iron.
The tool features a multi-lock clamping system with a top clamp and shim seat, ensuring secure insert retention, reduced vibration, and long insert life. Its 95° approach angle and right-hand cutting orientation make it suitable for general turning, facing, and profiling tasks.
Manufactured from hardened alloy steel, the MWLNR2020M08 ensures long service life and durability even under demanding machining environments. By combining robust construction, secure clamping, and compatibility with widely available WNMG inserts, this holder is an essential tool for precision and productivity in turning applications.
