DNMG150612 T9225 Tungaloy indexable turning insert — Turning, ISO DNMG geometry

The DNMG150612 T9225 Tungaloy insert is an ISO-compatible rhombic indexable plate designed for external and internal turning where toughness and wear resistance are required

• CVD-coated carbide grade T9225 for steel
• 55° rhombic geometry with 1.2 mm corner radius
• Double-sided chipbreaker and cylindrical hole

Durable grade for demanding steel turning

The CVD-coated carbide grade T9225 provides a balanced mix of wear resistance and fracture toughness, making it suitable for medium to heavy steel machining and moderately interrupted cuts. The applied coating enhances edge life at the temperatures typical of steel turning, so cycle times remain stable and tool changes are less frequent. This leads to improved process reliability and lower overall tooling expenditure when compared with uncoated grades. The robust substrate also supports repeatable results in shift-to-shift production.

Geometry engineered for secure seating and repeatable cuts

A 55° geometry in a rhombic DNMG form combines versatility with precise cutting angles for chamfering and finishing passes. The plate’s 1.2 mm corner radius and 0° relief angle give a predictable contact condition at the cutting edge, reducing vibration and workpiece deflection in less rigid set-ups. Compatibility with holders depends on form, relief angle, tolerance class, clamping method, size and thickness; the insert’s 6.35 mm thickness and cylindrical hole ensure secure clamping in standard external holders and boring bars, delivering consistent dimensional accuracy across batches.

Improved chip control and extended usable life

The double-sided chipbreaker design facilitates effective chip formation and evacuation across a wide range of feed rates, reducing recut and heat concentration at the cutting edge. Being double-sided, the plate offers multiple indexing positions, which extends the usable life before replacement is necessary and improves cost per cutting edge. For practical selection, pair the chipbreaker style and the T9225 grade to the workpiece material and the stability of the machining set-up to achieve optimal surface finish and throughput.

Easy integration into existing tooling systems

Supplied as an ISO indexable plate, the insert integrates into the common system build of an insert, matching external holder or boring bar, shim/clamp set and replacement screws. The plate is suitable for both external and internal turning operations; when fitting the insert, ensure the holder matches the DNMG form and the tolerance class to maintain clamping precision. The robust, universal character of the grade simplifies tool inventory and supports stand-by stock strategies for small- to medium-batch production.
