TNMG220416 T9225 — Turning insert by Tungaloy (ISO TNMG series)

A TNMG220416 T9225 ISO‑standard triangular insert for medium to heavy steel turning, offering a CVD‑coated carbide grade and a double‑sided chipbreaker for secure machining under variable engagement conditions

• CVD-coated carbide grade T9225
• ISO TNMG220416 triangular form
• Double-sided chipbreaker, with cylindrical hole
• Robust for medium to heavy steel turning

Reliable chip control and edge life for demanding turning

The insert uses a CVD‑coated carbide substrate in the T9225 grade, selected for toughness and resistance to flank wear in variable cutting conditions. The CVD coating provides a hard, wear‑resistant surface while preserving core toughness; this combination reduces flank wear and maintains cutting edge integrity during medium‑to‑heavy steel machining. The integrated chipbreaker promotes consistent chip formation and evacuation, which supports stable cutting forces and reduces the risk of built‑up edge during interrupted cuts.

ISO geometry ensures predictable holder compatibility

Manufactured to the ISO TNMG form, the insert’s compatibility with toolholders is defined by geometry, clearance, tolerance class, fastening and thickness. The standard triangular format and specified relief angle help to achieve predictable seating and repeatable positional accuracy in compatible external holders or boring bars. This consistency simplifies process planning and reduces set‑up variability in production environments that rely on indexed inserts for repeatable results.

Practical benefits in production: fewer interruptions, steady productivity

The double‑sided design and robust grade lower the frequency of index changes and spare‑part turnover, contributing to uninterrupted machining cycles. The insert is suitable where slightly interrupted cuts or fluctuating engagement demand additional toughness; as a result, tool life is enhanced and unplanned downtime is minimised. Selecting the appropriate chipbreaker and toughness grade for the workpiece material yields measurable gains in process reliability and surface finish quality.

System considerations and inventory optimisation

The insert forms part of a standard ISO turning system comprising the insert itself, a matching external holder or boring bar, a locating pad/clamping kit and replacement fastening screws. Using a double‑sided triangular insert reduces the number of distinct items kept in stock while ensuring several effective cutting edges per insert. When specifying replacements, check the inscribed circle size, plate thickness, hole style and relief angle to guarantee proper fit and clamp engagement in the chosen tooling system.

FAQ

What workpiece materials is this insert designed for?
The TNMG220416 T9225 insert by Tungaloy is engineered primarily for medium‑to‑heavy steel turning, optimised for applications with variable engagement and light interruptions.

How does the T9225 coating affect performance?
The T9225 CVD coating creates a wear‑resistant surface while retaining core toughness; this combination improves flank life and supports reliable chip formation under fluctuating cutting conditions.

Is the insert indexable and how does that influence inventory?
The triangular insert is double‑sided and indexable, which extends usable cutting edges per item and reduces the variety of inserts required in stock for comparable part families.

Which holder characteristics ensure proper fit for this insert?
Compatibility depends on form, relief/clearance angle, tolerance class, fastening method, size and thickness; matching these parameters ensures correct seating and repeatable performance.

What are the physical identifiers to check when ordering replacements?
Check the inscribed circle (22 mm), corner radius (1.6 mm), thickness (4.76 mm), hole style (cylindrical) and included angle (60°) to guarantee proper replacement and clamping.
