The VCGT220520 insert is primarily used as the core cutting element for positive rake turning tools, directly participating in external, internal and curved profile machining to deliver high-gloss surface finish. It is typically used in combination with 35° positive rake turning toolholders to achieve sharp cutting edge, low built-up edge and stable performance, especially crucial for precision finishing and light semi-finishing on aluminum alloy, copper and brass workpieces. It is suitable for automotive aluminum wheel hubs, new energy components, hydraulic aluminum parts, precision non-ferrous parts and general machinery manufacturing.
