TNMG 220404 T9225 CVD-coated carbide turning insert – Tungaloy

TNMG 220404 T9225 is an ISO-standard triangular turning insert designed for external and internal turning in medium to heavy steel machining.

• CVD-coated carbide for robust tool life
• Universal T9225 grade for medium–heavy steel
• 0.4 mm nose radius for fine finishing
• 60° triangular insert, double-sided chipbreaker

Consistent performance for demanding turning tasks

The CVD coating on this insert increases wear resistance while maintaining edge toughness, which supports longer tool life under varying cutting conditions. As a carbide grade developed for robustness, T9225 balances abrasion resistance and fracture toughness so that the insert performs reliably during medium to heavy turning of steel. This results in fewer indexings and steadier cycle times, helping to reduce process variability on production parts.

Practical compatibility and secure clamping

The insert follows the ISO geometry TNMG220404, so compatibility with holders is determined by form, relief angle, tolerance class, fixing method, size and thickness. The insert features a cylindrical hole for secure mounting and a standard 60° included angle that suits a wide range of triangular toolholders. Clear fitment and standardised dimensions simplify tool management and spare-part logistics in the workshop.

Improved chip control and surface quality

A double-sided chipbreaker design supports stable chip formation across interrupted cuts and changing engagement conditions. With a 0.4 mm nose radius, the geometry enables good surface finish without compromising edge strength, making this insert appropriate for finishing passes or mixed roughing‑finishing sequences. The chip control characteristics reduce the risk of workpiece damage and downstream rework.

Application guidance and process benefits

The insert is intended for external and internal turning of steel components where robustness and repeatable performance are required. When combined with an appropriate holder and correct cutting data, the grade delivers predictable tool life and steady process output. For technicians seeking practical advice, selecting the right chipbreaker and matching the insert to machine stability will yield the best balance between productivity and surface integrity.

FAQ

What materials is this insert suitable for?
The TNMG 220404 T9225 insert is formulated for medium to heavy steel machining; the T9225 grade offers robustness for varying engagement conditions.

How does the CVD coating help in production?
The CVD coating on the Tungaloy insert enhances wear resistance while retaining toughness, which supports longer tool life and steadier cycle times in everyday turning work.

Is the insert reversible and how is it mounted?
The insert is double-sided, allowing reversal to present a fresh cutting edge; it mounts via a cylindrical hole compatible with standard ISO TNMG toolholders.

Which operations suit the 0.4 mm nose radius?
A 0.4 mm nose radius is well suited for finishing passes and mixed roughing‑finishing tasks where a balance of surface quality and edge strength is required.

Where can matching holders and spare screws be obtained?
Matching holders, underplates and replacement screws can be sourced from Metav Werkzeuge; consult their technical team for optimal holder selection for the TNMG 220404 T9225 insert.
