TNMG220404 T9225 turning insert — CVD-coated carbide, 60° (Tungaloy)

A robust indexable turning insert, TNMG220404 T9225, designed for medium to heavy steel turning with reliable chip control and high resistance to flank wear.

• TNMG220404 geometry, 60° triangular insert
• CVD-coated carbide grade T9225 for steel
• Double-sided insert with 0.4 mm corner radius
• Cylindrical-hole design for secure clamping

Productivity and wear resistance for demanding steel machining

The combination of a CVD-coated surface and a tough carbide substrate delivers a balance between wear resistance and fracture toughness that is particularly valuable in variable cutting conditions. The T9225 grade is formulated for medium to heavy steel turning where interrupted cuts or changing engagement demand extra toughness. This results in longer tool life and fewer index changes, which improves uptime and reduces tool costs per component. The coating also enhances thermal stability at elevated cutting temperatures, supporting consistent surface finish during longer cycles.

Secure clamping and cost-effective indexing for shop-floor efficiency

Designed to the ISO TNMG form, the insert’s triangular shape and cylindrical hole enable straightforward, repeatable mounting in compatible holders. The double-sided configuration provides multiple usable cutting edges, halving the cost per edge compared with single-sided designs. Compatibility with a wide range of ISO holders is governed by form, clearance, tolerance class, fastening and thickness; this standardisation simplifies inventory and reduces changeover time. The 0.4 mm corner radius supports a mix of finishing and light roughing tasks while preserving edge strength under heavier feed rates.

Practical guidance for application and process stability

This insert is intended primarily for external and internal turning of steel in workshop and production environments; selecting the correct chipbreaker and cutting data tailored to the component material and rigidity of the setup is essential. A stable fixture, appropriate feed and conservative depths of cut at first trials will demonstrate the T9225’s balance of wear resistance and toughness. For interrupted cuts or variable engagement, the grade’s increased toughness reduces the risk of chipping. Where finer surface finish is required, reduce feed and exploit the insert’s sharper geometry to achieve consistent results.
