DNMG 110408 T9225 turning insert — CVD-coated carbide, 55° rhombic, Tungaloy

The DNMG 110408 T9225 is a CVD-coated, double-sided turning insert designed for medium to heavy-duty turning applications where interrupted cuts or variable engagement demand enhanced toughness and reliable chip control.

• CVD-coated carbide grade T9225
• Robust universal grade for medium to heavy steel
• ISO DNMG rhombic insert, 55° cutting angle
• Double-sided with cylindrical hole

Faster, more consistent metal removal for steel turning

The combination of a CVD-coated surface and a tough cemented carbide substrate delivers a pragmatic balance between wear resistance and fracture toughness. This insert is intended for productive steel machining where changing engagement or slightly interrupted cuts occur; the T9225 grade supports extended cutting intervals and stable performance under such conditions. Compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness, so selection should follow the established ISO match between the insert and the chosen external holder or boring bar. The rhombic geometry with a defined 55° cutting angle helps maintain cutting force distribution and supports predictable chip formation.

Predictable tool life and reliable surface finish

The insert’s geometry and the double-sided chipbreaker design aid chip control while preserving the cutting edge, which reduces unplanned tool changes and improves process economy. A 0.8 mm radius at the cutting edge increases edge strength for heavier cuts and contributes to consistent surface integrity on the workpiece. The modest 4.76 mm thickness and standard 11 mm size ensure mechanical stability when clamped correctly in a matching ISO DNMG holder; the central cylindrical hole grants secure fixation and straightforward indexing. These features combine to lengthen effective tool life and cut-cycle reliability, which is particularly valuable in serial production and job-shop environments.

System integration and practical recommendations

The insert forms part of a system: the ISO turning insert, a suitable external holder or boring bar, a shim/clamping kit and replacement screws are the recommended assembly for safe and repeatable use. The DNMG110408 is double-sided and indexable, enabling two cutting edges per side and economical utilisation of the insert geometry. For best results, pair the T9225 grade with a chipbreaker that matches the workpiece material and the machining stability—this balances surface finish and removal rates while managing heat and chip evacuation. Selection of speeds and feeds should reflect the material class and machine condition to exploit the grade’s strength without overloading the cutting edge.

FAQ

What materials is this insert suited for?
The T9225 grade and CVD-coated carbide substrate are optimised for steel machining, providing a robust compromise between wear resistance and toughness for medium to heavy-duty turning.

How is the insert mounted and indexed?
The insert uses a central cylindrical hole for secure clamping in compatible ISO DNMG holders and is double-sided and indexable to allow multiple cutting edges before replacement.

Which holder attributes must be matched to the insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the chosen holder or boring bar matches these ISO parameters.

Does the insert perform well with interrupted cuts?
Yes, the T9225 grade is formulated for situations with variable engagement or light interruptions, offering increased toughness to reduce the risk of chipping.

Is the geometry suitable for finishing or roughing operations?
The 0.8 mm radius and robust grade make the insert versatile; it is best used for medium to heavy cutting where edge strength is required, while finer radii would be preferable for high-precision finishing.
