CPMT080204 T5115 CPMT Turning insert — 80° rhombic, CVD-coated (Tungaloy)

The CPMT080204 T5115 is an ISO‑standard rhombic turning insert engineered for external and internal turning, optimised for cast iron machining.

• CVD-coated carbide for high wear resistance
• 80° rhombic geometry for stable cutting
• Single-sided chipbreaker for controlled chips
• ISO-compatible size 08, 0.4 mm radius

Extended tool life through balanced grade and coating

The CVD-coated T5115 grade is a universal solution for cast iron, offering a balanced combination of wear resistance and edge stability. The use of a CVD layer on cemented carbide provides a hard, wear-resistant surface that reduces flank wear while maintaining cutting-edge integrity, which translates to longer tool life and fewer insert changes. Given its universal character, this grade supports productive turning operations where consistent performance across a range of cast-iron materials is required.

Predictable machining and improved chip control

An 80° geometry combined with a 0.4 mm nose radius and a single-sided chipbreaker promotes stable cutting forces and predictable chip formation. The rhombic form gives reliable seat and clearance in standard toolholders, while the chipbreaker design helps direct chips away from the workpiece, improving surface finish and reducing rework. The insert’s 11° clearance angle and the specified hole with a single-side countersink (40°–60°) facilitate secure clamping and repeatable positioning in ISO-compatible clamping systems.

Simple system integration for efficient workshop use

This insert is part of the ISO turning insert system and is compatible with standard external holders, boring bars, support pads and clamping kits when matched by form, clearance angle, tolerance class, attachment, size and thickness. The combination of ISO-standard designation, the clearly defined thickness and the central hole design ensures straightforward retrofitting into existing setups; appropriate selection of chipbreaker and grade according to workpiece material and process stability supports efficient, reproducible machining cycles. For complex or critical applications, consultation on holder selection and cutting parameters enhances process reliability.

FAQ

What materials is this insert primarily suited for? The CPMT080204 T5115 insert is specified as a universal grade for cast iron, offering a balanced mix of wear resistance and edge stability for a broad range of grey and nodular cast iron turning tasks.

What is the nose radius and why is it important? The insert has a 0.4 mm nose radius; this small radius supports fine surface finish and dimensional control in finishing or semi-finishing turning operations where modest corner strength is required.

How does the T5115 coating affect performance? The CVD coating on the T5115 grade increases surface hardness and wear resistance, which helps maintain a sharp cutting edge longer and improves consistency under varying cutting conditions on cast iron.

Is this insert compatible with standard ISO holders? Yes; the insert is an ISO‑standard rhombic type and fits ISO‑compatible external holders and boring bars when matching form, clearance angle, tolerance class, attachment method, size and thickness.

What chip control can be expected with the single-sided chipbreaker? The single-sided chipbreaker is designed for controlled chip formation and evacuation, reducing the likelihood of entangling chips and supporting improved surface quality during turning.
