DNMG150412 T9225 DNMG turning insert by Tungaloy — CVD-coated carbide, ISO 55°

A DNMG150412 T9225 rhombic, ISO-standard turning insert designed for medium to heavy steel turning, offering a balance of toughness and wear resistance for variable cutting conditions

• ISO DNMG 150412 rhombic 55° geometry
• CVD-coated carbide grade T9225 for steel
• 1.2 mm corner radius for robust edge life
• Double-sided chipbreaker, reversible insert

Reliable cutting performance under changing conditions

The combination of CVD-coated carbide and the T9225 grade delivers reliable toughness for medium to heavy steel turning where intermittent cuts or variable engagement demand extra resilience. The coating improves wear resistance and reduces built-up edge, while the substrate composition gives the cutting edge sufficient toughness to withstand moderate interruptions. This results in more consistent cycle times and fewer unexpected tool changes, supporting higher throughput on batch and single-part production alike.

Fast integration into ISO tool systems to reduce downtime

Built to the ISO DNMG150412 standard, the insert integrates easily with compatible holders thanks to defined form, relief angle and dimensional tolerances. The rhombic 55° geometry and the cylindrical hole ensure secure clamping and repeatable positioning, simplifying tool changeover and minimising set-up time. Compatibility is determined by form, free angle, tolerance class, fastening method, size and thickness, allowing a predictable replacement process within existing turning tool systems.

Greater edge security and consistent surface quality

A 1.2 mm corner radius provides an enlarged cutting edge for improved resistance to chipping and extended edge life, which in turn contributes to steadier surface finish and reduced rework. The double-sided chipbreaker design offers reversible use of the insert for cost-effective edge rotation and economical tooling. This combination supports productive machining of external and internal turning operations while maintaining controlled chip formation and workpiece integrity.

FAQ

Is the insert suitable for interrupted cuts and mixed engagement conditions?
The DNMG150412 T9225 insert, with its CVD-coated carbide combination and tougher T9225 grade, is intended for medium to heavy turning where occasional interruptions occur, offering improved edge security under changing engagement.

Which workpiece materials are recommended for this grade?
The T9225 grade is developed for steel machining, particularly where a balance of wear resistance and toughness is required for medium to heavy steel turning operations.

How does the double-sided chipbreaker affect tool economics?
The reversible, double-sided chipbreaker on this indexable insert allows edge rotation and reuse, effectively increasing available cutting edges and lowering tooling cost per edge while maintaining consistent chip control.

Is the DNMG150412 compatible with existing ISO DNMG holders?
The insert follows the ISO DNMG150412 designation; compatibility depends on matching form, free angle, tolerance class, fastening method, size and thickness to the holder—this standardisation generally enables straightforward interchange within ISO systems.

What are the main dimensional values to check before ordering replacements?
Key dimensions for the insert are the inscribed circle (15 mm), plate thickness (4.76 mm), corner radius (1.2 mm), and insert angle (55°); confirm relief angle and hole style for correct clamping.
