CNMA 160612 T515 – ISO turning insert for turning, CVD-coated carbide (Tungaloy)

The CNMA160612 T515 is an ISO rhombic turning insert engineered for the economical machining of cast iron, featuring a CVD-coated carbide grade and an 80° cutting geometry for reliable performance.

• ISO rhombic insert CNMA 160612 T515
• CVD-coated carbide for cast iron machining
• 80° geometry with 1.2 mm corner radius
• Cylindrical-hole design, 6.35 mm thickness

Economical cast iron machining with CVD-coated carbide

The combination of CVD-coated surface technology and carbide substrate in grade T515 is designed to deliver stable chip formation and extended tool life when turning cast iron. The chemical vapour deposition layer improves wear resistance and reduces edge breakdown, which results in fewer tool changes and lower overall machining costs. For operations where interrupted cuts, varying stability and moderate to high cutting speeds occur, this insert offers a balanced performance that supports continuous production with predictable tool-life behaviour.

Geometry and clamping that secure repeatable results

The rhombic 80° geometry with a 1.2 mm corner radius provides a secure cutting edge for external and internal turning, promoting dimensional control and improved surface quality on cast iron components. The insert is supplied with a cylindrical hole to match standard ISO clamping systems and has a 6.35 mm thickness, which contributes to mechanical rigidity in the toolholder. Compatibility with the holder is determined by form, clearance angle (0° relief), tolerance class, clamping method, size and thickness, ensuring interchangeability within ISO systems and straightforward tool set-up in automated or manual turning centres.

System benefits that raise workshop productivity

This insert is part of an ISO insert system that includes a matching external holder or boring bar, a backing/clamping kit and replacement screws; these system elements together reduce downtime during tool changes and simplify inventory management. The straightforward specification—ISO designation, T515 grade, rhombic form—makes it easier to select a matching holder and to maintain consistent cutting parameters across batches. For procurement and process planning this results in measurable gains: fewer set-ups, consistent component quality and economical use of carbide grades for high-volume cast iron turning.
