The WTJNR 2020K16 is a strong and versatile external turning tool holder designed for general turning, profiling, and roughing operations on CNC and conventional lathes. It is specifically designed to hold TNMG carbide inserts with a 60° triangular geometry, offering excellent edge strength and versatility in medium to heavy-duty machining.
Featuring a 20×20 mm shank and right-hand cutting orientation, this holder provides rigidity and reduces vibration, ensuring stable cutting performance and extended tool life. The WTJNR pocket design ensures secure clamping and accurate insert positioning, delivering consistent results in both continuous and interrupted cuts. The 93° approach angle allows efficient material removal while maintaining smooth chip flow and good surface finish.
The WTJNR 2020K16 is widely used in industries such as automotive, aerospace, and general engineering, where productivity and repeatability are key. Paired with TNMG 1604 inserts, it provides reliable performance in steels, stainless steels, and alloy materials under various machining conditions.
