TNMG160404 160404 T9225 — Turning insert (ISO, CVD-coated) by Tungaloy

TNMG160404 T9225 Tungaloy turning insert for ISO-standard external and internal turning, designed for medium to heavy steel machining with intermittent cuts and variable engagement.

• Robust CVD-coated carbide grade T9225
• ISO 60° triangular geometry for broad compatibility
• Double-sided chipbreaker for consistent chip control
• Cylindrical hole and 4.76 mm thickness for secure clamping

Efficient performance for medium to heavy steel turning

The insert delivers a balance of toughness and wear resistance thanks to the CVD-coated carbide grade T9225, made for applications with variable engagement and occasional interruptions. This results in fewer edge failures and longer effective tool life, which in turn reduces downtime and tooling costs. The 60° triangle geometry provides economical indexing and versatile cutting angles, helping to sustain a stable process across a wide range of turning tasks.

Compatibility and secure mounting reduce set-up time

Compatibility with toolholders is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The ISO-standard format and the cylindrical hole permit straightforward mounting in matched external holders or boring bars, while the 4.76 mm plate thickness and 16 mm inscribed circle ensure reliable clamping and repeatable seating. Specifying matching shims and clamping sets streamlines set-up and minimises rework between insert changes.

Practical design that improves chip control and surface finish

The insert features a double-sided chipbreaker, optimised for medium to heavy turning, which shapes chips consistently and reduces the risk of snarling in boring operations. Stable chip formation supports a better surface finish and lowers the probability of workpiece damage during interrupted cuts. The modest corner radius (0.4 mm) offers a compromise between edge strength and the ability to achieve fine surface qualities where required.

System approach and recommended use cases

Treat the insert as part of a system: the insert, a matched external holder or boring bar, an appropriate underlay/clamping kit and replacement screws. Use the grade for turning steel in production and repair environments where engagement conditions vary or where slightly interrupted cuts demand additional toughness. When high precision or specific tolerances are required, pair the insert with holders certified to the same ISO tolerance classes for predictable results.

FAQ

What materials is this insert suited for?
The Tungaloy TNMG160404 T9225 is intended primarily for steel machining and performs well in medium to heavy turning where variable engagement or interrupted cuts demand toughness.

How does the CVD coating benefit cutting performance?
The CVD-coated carbide surface increases wear resistance and protects the cutting edge under cyclic loads, helping the TNMG160404 maintain cutting stability and extend time between indexings.

Can this insert be used for internal and external turning?
Yes — the triangular ISO geometry and cylindrical hole allow mounting in compatible external holders or boring bars for both external and internal turning operations.

What does the 0° clearance angle mean in practice?
A 0° clearance angle indicates a neutral relief suited to certain holder geometries; correct holder selection and seating are crucial to ensure proper cutting edge clearance and repeatable results.

How many cutting edges are available per insert?
The triangular form with double-sided chipbreaker provides multiple indexable cutting edges; index and reclamp according to the holder’s recommended procedure for safe re-use.
