DNMG110408 T9225 — Tungaloy ISO turning insert for turning

The DNMG110408 T9225 Tungaloy turning insert is an ISO-standard, rhombic indexable insert engineered for medium-to-heavy steel turning where toughness and reproducible performance are required.

• CVD-coated carbide grade T9225
• Designed for medium to heavy steel turning
• 55° rhombic geometry, 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole for clamping

Reliable productivity for medium-to-heavy turning

The combination of a CVD-coated surface and a robust universal grade (T9225) offers predictable wear behaviour under changing engagement conditions. The coating increases thermal and abrasive resistance, which results in reduced flank wear and longer in-process life compared with uncoated grades. This translates into fewer insert changes and improved machine uptime, particularly during demanding external and internal turning tasks. The geometry is optimised for a balance between strength and surface finish, making the insert suitable for productive roughing and consistent semi-finishing operations.

Secure clamping and straightforward holder compatibility

As an ISO-standard indexable insert, mechanical compatibility with toolholders is determined by form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole and matching relief specification ensure a secure, repeatable clamp engagement, reducing the risk of vibration-induced wear. The double-sided chipbreaker allows the insert to be indexed to fresh cutting edges, extending usable life and simplifying inventory management. Selection of the correct chipbreaker and grade depending on workpiece stability and cutting parameters will yield the best compromise between tool life and cycle times.

Practical guidance on application and coating benefits

The Tungaloy T9225 grade is a CVD-coated carbide designed for steel machining where intermittent cuts or variable depth of cut demand additional toughness. The 55° rhombic plate form with a 0° relief angle provides mechanical rigidity, while the 0.8 mm corner radius offers a durable cutting edge that withstands heavier engagements without sacrificing surface quality. In practice, the coating reduces adhesive wear and improves performance at elevated cutting speeds; pairing the insert with an appropriate coolant strategy and stable fixturing will deliver repeatable results and economical machining cycles.

FAQ

What materials is the DNMG110408 T9225 designed for?
The DNMG110408 T9225 Tungaloy turning insert is optimised for medium-to-heavy steel machining and offers a balance of toughness and wear resistance suitable for variable engagement conditions.

Will this insert fit standard ISO DNMG holders?
Compatibility follows ISO conventions: form, relief angle, tolerance class, clamping method, size and thickness determine fit; the DNMG110408 conforms to ISO dimensions and uses a cylindrical hole for secure clamping.

What are the main advantages of the T9225 CVD coating?
The CVD-coated T9225 grade improves thermal and abrasive wear resistance, lowering flank wear rates and allowing more consistent cutting performance at higher speeds compared with uncoated carbide.

Is the insert suitable for interrupted cuts or unstable conditions?
Yes, the robust universal characteristics of the T9225 grade and the insert’s geometry provide enhanced toughness for partially interrupted or fluctuating cuts encountered in heavy turning operations.

How does the 0.8 mm corner radius affect the machining result?
A 0.8 mm corner radius offers a compromise between edge strength and surface finish, improving edge life in heavy engagements while still delivering acceptable surface quality for many turning tasks.
