DNMG 150404 T9225 Wendeplatten - Tungaloy

Take advantage of the CVD-coated carbide grade T9225 and the ISO DNMG geometry with a 0.4 mm corner radius for reliable mid-to-heavy steel turning; order the insert via Metav Werkzeuge or request advice from our consultants if clarification is needed.

DNMG150404 T9225 Tungaloy indexable insert for turning – CVD-coated carbide, 55° rhombic

The DNMG150404 T9225 is an ISO rhombic indexable insert designed for external and internal turning, offering a robust universal grade for medium-to-heavy steel machining where variable engagement or mildly interrupted cuts demand enhanced toughness.

• ISO DNMG geometry, 55° cutting angle
• CVD-coated carbide grade T9225
• 0.4 mm corner radius for versatile profiles
• Double-sided chipbreaker with cylindrical hole

Consistent productivity under demanding cutting conditions

The CVD-coated carbide grade T9225 delivers a deliberate balance of toughness and wear resistance, making this insert well suited to continuous and semi-interrupted steel turning operations. The coating increases tool life under heat and abrasion, while the substrate supports moderate impact loads; together they reduce tool change frequency and maintain steady production rates. Compatibility with holder systems is determined by form, relief angle, tolerance class, fastening method, size and thickness, so the insert integrates into existing tool programmes without compromising process stability.

Improved surface quality and effective chip control

A double-sided chipbreaker and the rhombic DNMG geometry provide reliable chip control and repeatable edge behaviour, which helps to achieve a consistent surface finish during roughing and finishing passes. The 0.4 mm corner radius offers a compromise between edge strength and profile definition, improving resistance to chipping while permitting tight diametral tolerances. The neutral 0° relief angle aids versatility across a range of cutting conditions; selecting the appropriate chipbreaker and feed rates ensures the best balance between material removal rate and part accuracy.

System-level advantages and straightforward handling

Supplied as an ISO-standard indexable insert, this component forms part of a complete tooling system comprising an appropriate external holder or boring bar, a 4.76 mm plate thickness, a shim/clamping set and replacement screws. The cylindrical hole facilitates precise locating and secure fastening, while the reversible, double-sided design extends usable life and reduces inventory cost per cutting edge. For shops seeking predictable performance in steel machining, choosing the right holder and cutting parameters together with this insert yields measurable gains in uptime and process reliability.

FAQ

Is this insert suitable for steel turning applications?
Yes. The DNMG150404 T9225 insert from Tungaloy is a robust universal grade designed specifically for medium-to-heavy steel machining, offering wear resistance and toughness for variable cutting conditions.

Can the insert be used for both external and internal turning?
Yes. The insert’s rhombic DNMG geometry and cylindrical hole allow use in external holders and appropriate boring bars for internal turning, provided the holder matches the ISO form, size and tolerance class.

How does the double-sided chipbreaker affect performance?
The double-sided chipbreaker on this Tungaloy insert promotes controlled chip formation and consistent edge behaviour, improving surface finish and extending usable tool life through reversible indexing.

What determines compatibility with a chosen holder?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the ISO DNMG series is designed to fit compatible external and internal holders when these parameters match
