Cargo Carbide TNMG-U CO15C Carbide Turning Inserts are designed for CNC turning and machining applications involving cast iron. The CO15C grade is recommended by Cargo Carbide for cast iron machining and is identified as a black carbide grade in the company's grade chart.

The TNMG-U geometry is a negative triangular turning insert configuration designed for use with compatible TNMG tool holders. Cargo Carbide's published technical information lists the TNMG-U family in 160404, 160408 and 160412 sizes, providing 0.4 mm, 0.8 mm and 1.2 mm nose-radius options.

Cargo Carbide TNMG-U CO15C provides a dedicated carbide tooling option for manufacturers machining cast iron components on CNC lathes. The combination of TNMG geometry and CO15C cast-iron grade can be selected according to the workpiece, machining operation, cutting depth, feed rate, machine rigidity and required surface finish.

The product is suitable for cast iron turning applications in general engineering, automotive components, machine components, housings and industrial castings, when used with appropriate cutting conditions.

Technical Specifications

Cargo's published cast-iron insert document marks TNMG-U 160404, 160408 and 160412 as recommended with CO15C.

Available Sizes
