TNMG160412 T9225 Tungaloy indexable insert for turning, CVD-coated carbide, 60°

The TNMG160412 T9225 is an ISO-standard triangular indexable insert designed for external and internal turning, offering a universal CVD-coated carbide grade suited to medium to heavy steel machining.

• CVD-coated carbide for wear resistance
• Universal T9225 grade for medium/heavy steel
• ISO TNMG 160412 triangular form 60°
• Through-hole, cylindrical bore for secure fixing

Consistent cutting performance where process reliability matters

The TNMG160412 T9225 insert brings together a CVD-coated surface and a carbide substrate to deliver a balance of hardness and toughness. The chemical vapour deposition layer increases thermal and abrasive resistance, which extends tool life under higher cutting temperatures and interrupted cuts. For production environments this translates into fewer unexpected tool changes and more predictable cycle times. The triangular ISO TNMG geometry provides three usable edges per side, reducing tooling cost per cutting edge while maintaining consistent chip control thanks to the double-sided chipbreaker design.

Practical compatibility and quick indexability for efficient changeovers

Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The insert’s 16 mm inscribed circle, 4.76 mm thickness and 1.2 mm nose radius allow straightforward matching with common external holders and boring bars. The through-hole with a cylindrical bore ensures secure fastening and repeatable seating, so clamping incidents are minimised. In practice, a correctly matched holder and the standardised TNMG shape simplify inventory management and speed up maintenance routines, helping workshops reduce downtime and maintain steady output.

Adaptability to varied steel machining tasks and clear selection criteria

The T9225 grade is formulated as a robust universal choice for medium to heavy steel machining where varying engagement or slightly interrupted cuts require extra toughness. Selecting the right chipbreaker and grade for the specific workpiece and operation is crucial: smoother finishes benefit from finer nose radii, while heavier cuts call for the tougher grade and a more positive chip control geometry. The insert’s 60° included angle is well suited to turning profiles and facing operations, providing a good compromise between edge strength and accessibility for shoulder and fillet work.

Cost-efficiency through predictable life and lower per-edge expense

Using a multi-edge, indexable solution reduces the effective cost per cutting edge and contributes to process economics. The combination of T9225 carbide chemistry and CVD coating supports repeatable performance over extended runs; this reduces scrap risk and the frequency of unplanned interventions. For job shops handling mixed batches or shops running serial production, the TNMG family helps balance stock variety with effective coverage of common turning tasks. Metav Werkzeuge can advise on optimised cutting data and holder pairings to realise the full productivity gains.

FAQ

What materials is this insert best suited for?
The TNMG160412 T9225 insert is designed primarily for medium to heavy steel machining; the T9225 grade provides the toughness needed for interrupted cuts and variable engagement.

How many cutting edges are available per insert?
The triangular TNMG form provides three corners per side and, with a double-sided configuration, multiple indexable edges before disposal — this lowers the effective cost per edge.

Does the insert require a special holder type?
Holder compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness; the TNMG160412 requires a holder matching ISO TNMG specifications for correct seating and clamping.

What benefits does the CVD coating bring in daily use?
The CVD coating on this carbide insert improves thermal and abrasive resistance, resulting in longer life under higher cutting temperatures and enhanced wear resistance during serial production.
