The VCGT160408 insert is primarily used as the core cutting element for positive rake turning tools, directly participating in external turning, internal boring and contour profiling to achieve smooth chip removal and high-precision surface finish. It is typically used in combination with 35° rhombic positive rake turning toolholders to deliver sharp cutting edge and effectively prevent built-up edge, especially crucial for precision finishing and light semi-finishing on aluminum alloy, copper and other non-ferrous workpieces. It is suitable for automotive aluminum wheel hubs, new energy structural parts, hydraulic aluminum fittings, precision non-ferrous components and general machinery manufacturing.
