DCMT DCMT11T308 11T308 T9225 Turning Insert — 55° Rhombic, CVD-coated (Tungaloy)

A DCMT11T308 Tungaloy turning insert for ISO-compliant external and internal turning, optimised for medium-to-heavy steel machining where interrupted cuts and variable engagement demand toughness and stable chip formation

• CVD-coated carbide T9225 for robustness
• 55° rhombic geometry for versatile turning
• 0.8 mm corner radius for strong cutting edge
• Cylindrical hole + countersink 40°–60° for secure clamping

Reliable performance under variable cutting conditions

The CVD-coated carbide construction and T9225 grade combine wear resistance with toughness to maintain cutting-edge integrity during mixed and interrupted cuts. This composition was selected for process reliability in medium-to-heavy steel operations, where stable chip control and predictable tool life directly influence productivity. The result is fewer unscheduled tool changes and a more consistent surface finish, which supports efficient batch and single-piece manufacturing alike.

Secure clamping and straightforward ISO integration

Compatibility with ISO tool systems is determined by form, 7° clearance angle, tolerance class, toolholder compatibility, clamping and plate dimensions. The insert's 55° rhombic geometry, 3.97 mm thickness and 11 mm size make it suitable for a wide range of standard holders. The cylindrical hole with a single-side countersink (40°–60°) ensures positive locating and reliable clamping under higher cutting forces. Clear specification of these dimensions simplifies holder selection and reduces set-up time in production environments.

Economic efficiency and recommended applications

Designed for both external and internal turning, the insert is a practical choice when machining steel with occasional interruptions or varying engagement. The 0.8 mm corner radius balances edge strength and profile definition, extending service life while maintaining acceptable surface quality. For workshops seeking predictable costs and improved uptime, Tungaloy's combination of geometry and T9225 coating provides a cost-effective compromise between longevity and cutting performance; the DCMT11T308 type performs particularly well when paired with an appropriate single-side chipbreaker and a suitably rigid tool assembly.

FAQ

Which materials is this insert suitable for?
The insert is specified for medium-to-heavy steel machining; the T9225 grade and CVD-coated carbide make it particularly suitable for steel workpieces and operations with variable engagement.

How does the T9225 grade affect machining performance?
T9225 provides a balance of toughness and wear resistance; in practice the Tungaloy T9225 grade extends tool life under interrupted cuts while maintaining good edge stability.

What are the key dimensions to check for compatibility with a holder?
Check the ISO designation DCMT11T308, plate size 11, 3.97 mm thickness, 0.8 mm corner radius, and the 7° clearance angle to ensure correct fit and clamping in the chosen toolholder.

How is the insert clamped in the toolholder?
Clamping is achieved via the cylindrical hole with a single-side countersink (40°–60°); this provides precise locating and secure fixation when used with the appropriate clamp, shim and screw set.

For which turning applications is this insert recommended?
The insert is recommended for external and internal turning of steel components where moderate to heavy cuts and occasional interruptions are expected; the geometry and chipbreaker suit both roughing and mixed finishing tasks.
