DNMG150416 T9225 — turning insert, 55° rhombic, Tungaloy

DNMG150416 T9225 is an ISO rhombic turning insert designed for medium-to-heavy steel machining where toughness and reliable chip control are required

• CVD-coated carbide T9225
• Universal grade for medium to heavy steel
• Double-sided chipbreaker for interrupted cuts
• 55° rhombic form with cylindrical hole

Consistent performance where cutting conditions vary

The CVD-coated carbide grade T9225 delivers a balance of toughness and wear resistance that suits fluctuating engagement and lightly interrupted cuts. With a 1.6 mm corner radius and a double-sided chipbreaker, the insert provides stable chip formation and reduced edge chipping; the result is fewer tool changes and higher machining uptime. This directly supports predictable cycle times in mixed production runs and lowers overall tooling overhead through extended edge life.

Secure clamping and straightforward holder selection

Compatibility depends on form, clearance angle, tolerance class, fixing method, size and thickness. The rhombic 55° geometry with a cylindrical hole and 4.76 mm plate thickness ensures positive seating in standard ISO clamping systems and consistent repeatability when paired with the appropriate external holder or boring bar. Specifying matching holder geometry and tolerance class minimises vibration and improves surface finish, transforming a good setup into a reliably productive process.

Material and coating explained for reliable yields

The substrate is carbide with a CVD surface treatment engineered for demanding steel applications. CVD coating enhances hardness and heat resistance at the cutting edge while maintaining core toughness; this combination helps resist flank wear under elevated temperatures and sustained contact. For operators unfamiliar with coating technology, CVD-coated inserts typically offer a favourable compromise between wear resistance and chipping resistance compared with uncoated grades, making them suitable for a wide spread of steels and cutting conditions.

Practical applications and process guidance

Intended for external and internal turning, the insert excels in operations where interrupted cuts or variable depths of cut are common. When machining medium-to-heavy steel, select feeds and speeds that favour the insert's toughness—moderate cutting speeds and stable clamping reduce thermal shock and improve edge life. The rhombic geometry also allows for positive entry angles in shoulder turning and profile work, while the double-sided chipbreaker helps control stringy chips, thereby improving process safety and machine cleanliness.
