CNMA 120408 T9205 CNMA indexable turning insert by Tungaloy — CVD-coated carbide, 80° lead angle

A CNMA120408 T9205 indexable turning insert designed for productive external and internal turning of steel in stable machining conditions

• CVD-coated carbide for long tool life
• 0.8 mm corner radius for balanced strength
• ISO rhombic design for versatile turning
• Cylindrical hole for secure clamping

Extend cutting life with the CVD-coated T9205 grade

The grade is a CVD-coated carbide specifically formulated for wear resistance and productive turning of steel at elevated cutting speeds under stable setups. The chemical-vapour-deposited coating forms a hard, thermally resistant layer that delays flank and crater wear, which in turn preserves cutting geometry for longer intervals. This results in fewer insert changes and more uptime on the lathe, improving throughput while maintaining consistent dimensional results. The wear characteristics also support predictable regrinding or replacement intervals, enabling better process planning.

Consistent part quality through precise geometry and stable clamping

The rhombic plate geometry with an 80° lead angle provides a balance between cutting strength and access for external and internal turning. A 0.8 mm corner radius helps absorb cutting forces for medium to finishing cuts while supporting a good surface finish, especially when run in a stable clamping arrangement. The insert’s ISO-indexed format and rhombic shape make it suitable for a wide range of ISO holders, and the cylindrical hole enhances secure seating and repeatability when combined with the correct clamping set. Together these features help produce consistent components batch after batch.

Integrate smoothly into existing turning systems and workflows

Compatibility with toolholders is determined by form, clearance, tolerance class, fastening, size and thickness; the insert forms part of an ISO insert–holder–clamp system that keeps tool changes and setup straightforward. Supplied without a chipbreaker, the grade lets shops select the most appropriate chip control geometry for the workpiece and process stability. The neutral 0° rake/clearance angle and 4.76 mm thickness contribute to rigidity for interrupted cuts and stable finishes. Using this insert within a matched holder and clamping kit streamlines inventory and reduces sorting time at the machine.
