DNMA 150608 T5105 turning insert — CVD-coated carbide, 55° rhombic (Tungaloy)

DNMA150608 T5105 is an ISO-format rhombic turning insert designed for high-speed machining of cast iron under stable machining conditions.

• ISO rhombic insert, 55° cutting angle
• CVD-coated carbide T5105 for high wear resistance
• Suitable for high-speed cast-iron turning
• Cylindrical hole and 6.35 mm thickness for secure clamping

High-speed performance with a wear-resistant grade

The T5105 grade is a CVD-coated carbide engineered for sustained performance during high-speed operations on cast iron. Its coating increases resistance to abrasive wear and maintains cutting-edge integrity, which reduces the frequency of insert changes and supports predictable process windows. For production environments where cycle time and tool lifetime are key performance indicators, the combination of grade and geometry offers measurable stability and fewer stoppages for tool change.

Geometry and clamping for consistent results

The rhombic DNMA form with a 55° cutting angle and a cylindrical locating hole provides reliable seating in compatible toolholders. The insert’s 6.35 mm thickness and 0.8 mm corner radius give a balance between rigidity and finishing capability, suitable for both light finishing passes and moderate roughing when the setup is stable. The absence of a predefined chipbreaker means chip control must be matched to the operation and workpiece; selecting the correct holder and process parameters ensures consistent surface quality and repeatable dimensions.

Process benefits and economic efficiency

Using an ISO-format indexable insert streamlines tool logistics and simplifies replacement routines across compatible holders. The CVD coating and wear-focused substrate extend usable life under the recommended conditions, which translates into lower tooling consumption per part and improved overall equipment effectiveness. For batch production or long single-part runs on cast iron, this insert supports steady output and predictable consumable costs while maintaining machining accuracy.

System compatibility and practical considerations

The insert is part of an ISO insert system that requires a matching external holder or boring bar, a backing clamp or clamping kit, and compatible screws for secure fastening. Compatibility is determined by shape, clearance angle, tolerance class, fixation method, size and thickness; selecting a holder with the correct seat and screw arrangement ensures repeatable clamping and safe cutting conditions. For application planning, note the insert’s specifications so that the toolholder selection and process parameters are aligned with the machining task.

FAQ

What materials is this insert optimised for?
The DNMA150608 T5105 insert from Tungaloy is optimised for cast iron machining at high cutting speeds under stable conditions.

Which holder geometry is required for secure clamping?
The insert requires a compatible ISO rhombic seat with the correct pocket for a DNMA profile and a clamping screw arrangement that matches the insert’s cylindrical hole and thickness.

Does the insert include a chipbreaker?
This grade and geometry are delivered without a chipbreaker, allowing process engineers to select chip control via holder geometry and cutting conditions.

How does the T5105 grade affect tool life?
The T5105 CVD-coated carbide provides enhanced abrasive wear resistance, which extends edge life in appropriate high-speed cast-iron applications and supports predictable replacement intervals.

Can this insert be used for internal turning or only external?
The DNMA form is primarily used for external turning; compatibility for internal boring depends on the selected holder and the machine’s access constraints.
