TNMG160408 T9225 TNMG turning insert for turning by Tungaloy

TNMG160408 is a triangular ISO turning insert designed for medium to heavy steel turning, offering a CVD-coated carbide grade for increased toughness and consistent chip control.

• CVD-coated carbide T9225 for toughness
• Triangular 60° geometry for versatile turning
• Double-sided chipbreaker for consistent chips
• Cylindrical hole for secure mounting

Consistent cutting performance for demanding steel turning

The TNMG160408 insert, produced in the T9225 grade, combines a CVD-coated surface with a tough carbide substrate to deliver a balance of wear resistance and fracture toughness. This combination is particularly effective when machining stainless and alloyed steel under varying engagement conditions or when cuts are slightly interrupted. The coated surface reduces flank wear and the substrate resists chipping, which contributes to longer tool life and more stable dimension control in production runs. Emphasis is placed on reliable, repeatable results rather than speculative claims.

Clear guidance on compatibility and clamping benefits

ISO conformity ensures predictable fit and replacement behaviour: compatibility with a toolholder is defined by form, clearance angle, tolerance class, fastening design, size and thickness. The insert features a 60° triangular shape and a cylindrical hole, enabling secure clamping in standard ISO-compatible holders and bar tooling. The double-sided chipbreaker design assists chip control on both positive and neutral seating angles, and the specified 0° clearance suits particular holder geometries where neutral relief supports stable cutting forces. These characteristics reduce setup uncertainty and simplify integration into existing turning tool systems.

Practical application advantages and handling notes

Designed as a robust universal grade, this insert is intended for external and internal turning operations where a compromise between durability and toughness is required. The 0.8 mm corner radius provides a balance between edge strength and surface finish, while the 4.76 mm thickness and 16 mm size support rigidity in moderate depth-of-cut scenarios. For optimal results, choose the chipbreaker and grade matching the workpiece material and feed conditions; the T9225 grade is especially suitable when a slightly tougher edge is needed to handle unstable cuts. Regular inspection of the cutting edge and correct clamping torque will preserve the expected performance and consistency.

FAQ

Is this insert suitable for interrupted cuts and variable engagement?
The Tungaloy TNMG160408 in grade T9225 is specified as a robust universal grade suitable for medium to heavy steel turning and for conditions with changing engagement where higher toughness is required.

Which holder types fit the TNMG160408?
ISO-compatible triangular holders and bar tooling designed for TNMG inserts with a cylindrical hole accommodate the TNMG160408 when form, clearance, tolerance class, fastening and thickness match the holder specifications.

What advantages does the CVD coating provide on this insert?
The CVD-coated layer on the carbide substrate reduces flank and crater wear, contributing to longer life and more consistent surface finish during prolonged steel turning operations.

How does the double-sided chipbreaker affect performance?
The double-sided chipbreaker supports reliable chip formation on both seating faces, improving chip control and repeatability in a range of turning conditions.

What dimensions are critical when checking compatibility?
Key dimensions include the 16 mm size, 4.76 mm plate thickness, 0.8 mm corner radius and the 60° shape angle; these determine fit and suitability for specific holders and cutting conditions.
