The TCGT16T304-AK insert is primarily used as the core cutting element for positive rake turning tools, directly participating in external turning, internal boring and contour machining to achieve smooth chip removal and high-quality surface finish. It is typically used in combination with triangular positive rake turning toolholders to deliver sharp cutting edge and resist built-up edge, especially crucial for precision finishing on aluminum alloy, copper and brass workpieces. It is suitable for automotive aluminum parts, new energy components, hydraulic fittings, precision non-ferrous components and general machinery manufacturing.
