DCMT 070208 T5115 turning insert (ISO) by Tungaloy — CVD-coated carbide, 55° rhombic

A DCMT070208 T5115 indexable turning insert designed for general-purpose turning of cast iron, offering stable cutting edges and reliable chip control in ISO-format tool systems.

• CVD-coated carbide T5115 grade
• Optimised for cast iron machining
• Rhombic 55° geometry, 0.8 mm nose radius
• Single-sided chipbreaker with hole and countersink

Consistent wear resistance for cast-iron turning

The T5115 grade is a CVD-coated carbide developed as a universal solution for cast iron, combining wear resistance with edge stability. The chemical vapour deposition layer increases hardness at the surface while retaining a tough substrate, which reduces flank wear and extends tool life under interrupted cuts. As a result, operators benefit from longer tool life and fewer insert changes, which supports a more economical machining process and predictable production planning.

Geometry that balances finish and strength

A 55° rhombic outline and a 0.8 mm nose radius deliver a balance between cutting-edge strength and surface finish. The 55° geometry provides good access for both external and internal turning, while the moderate radius reduces the risk of edge chipping on unstable setups. The insert’s 7° clearance angle and 2.38 mm thickness contribute to a rigid cutting edge, improving dimensional stability and repeatability when paired with an appropriate holder. These geometric choices make the insert suitable for a wide range of turning tasks, from light finishing to more productive roughing passes.

ISO system compatibility and practical assembly guidance

As part of the ISO turning insert family, compatibility with toolholders depends on form, clearance angle, tolerance class, fastening style, size and thickness; select the matching holder, shim and clamping screws for secure mounting. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for positive clamping and straightforward replacement. For best results, match the single-sided chipbreaker to the workpiece and machining conditions: the chip control geometry reduces entanglement and improves evacuation when turning cast iron. The modular system—insert, holder, shim and fastener—ensures quick changeovers and minimal downtime in production environments.

FAQ

What materials is this insert designed for?
The insert is specified as a universal grade for cast iron machining; the T5115 CVD-coated carbide provides a balance of wear resistance and edge stability for grey and nodular cast irons.

Can this insert be used for internal turning as well as external turning?
Yes, the rhombic 55° geometry and ISO format allow use in both external and internal turning operations when the correct holder and clamping are selected.

How does the chipbreaker affect machining performance?
The single-sided chipbreaker on this insert improves chip control for cast iron, aiding evacuation and reducing re-cutting of chips, which supports surface quality and tool life.

What must be considered when selecting a holder for this insert?
Choose a holder that matches the insert’s form, clearance angle (7°), tolerance class, fastening method and plate thickness (2.38 mm) to ensure secure clamping and precise positioning.
