CNMG 120408 T9205 ISO turning insert by Tungaloy — CVD-coated carbide, double-sided chipbreaker

The CNMG120408 T9205 is an ISO-form turning insert designed for productive external and internal turning of steel, offering a wear-resistant CVD-coated carbide grade for higher cutting speeds.

• CVD-coated carbide for high wear resistance
• Optimised for steel at higher cutting speeds
• Double-sided chipbreaker for reliable chips
• ISO CNMG 120408 form with 0.8 mm radius

Durable grade for sustained productivity

The CVD-coated T9205 grade combines a hard wear layer with a tough substrate to deliver consistent tool life under stable turning conditions. This coating reduces abrasive wear and preserves the cutting edge at higher cutting speeds, which translates into fewer tool changes and more uptime on the shop floor. For component manufacture where repeatable results and cost-efficient machining are priorities, the wear behaviour of this grade supports predictable process windows and reduced scrap rates.

Geometry and mounting that ensure process stability

The rhombic ISO geometry with an 80° approach angle and a 0.8 mm corner radius provides a balanced compromise between strength and surface finish. The insert features a cylindrical hole for secure clamping and a thickness of 4.76 mm that suits a wide range of standard CNMG holders. The double-sided chipbreaker allows reversible use of both cutting edges, optimising the number of effective edges per insert. Compatibility with a holder depends on form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures safe fixation and stable cutting conditions.

Practical application guidance for reliable turning

Intended primarily for the productive turning of steel, this insert performs best when paired with a stable setup and the correct chipbreaker suited to the workpiece and machining strategy. The ISO-series system comprises the insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws; ensuring all system parts are specified correctly reduces vibration and improves surface quality. With its wear-resistant carbide and engineered chip control, the insert contributes to repeatable surfaces and predictable tool change intervals, supporting process planning and lean production practices.

FAQ

What materials is this insert suitable for?
The CNMG120408 T9205 insert is optimised for turning steel, benefiting from the T9205 grade’s wear resistance and performance at higher cutting speeds.

How does the double-sided chipbreaker affect usage?
A double-sided chipbreaker allows reversible use of both cutting edges on the insert, effectively extending the number of usable edges and improving cost-efficiency during machining.

Which holder attributes must be checked for compatibility?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; ensuring these match the holder avoids clamping issues and instability.

What are the key dimensional data for planning?
Use the designation CNMG120408, 12 mm size, 4.76 mm thickness and 0.8 mm corner radius when specifying holders and machining parameters for accurate integration.
