VCMT 080204 T5115 – VCMT080204-CM indexable insert for turning (Tungaloy)

A VCMT080204-CM T5115 indexable insert designed for ISO-compliant external and internal turning, optimised for cast iron with a balanced mix of wear resistance and edge stability

• CVD-coated carbide grade T5115
• ISO rhombic 08 geometry
• 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent edge life through CVD-coated carbide for cast iron

The combination of CVD-coated carbide and the T5115 grade delivers a reliable balance of wear resistance and edge stability for turning cast iron. The chemical vapour deposition layer reduces flank wear while maintaining a robust cutting edge, which translates into longer tool life and fewer index changes. This effect is particularly beneficial in production environments where predictable service intervals and reduced downtime increase overall throughput and cost-efficiency.

ISO compatibility and secure clamping for repeatable machining

The ISO rhombic form and standard dimensions ensure compatibility with a wide range of turning holders and boring bars. Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; the insert features an 08 size, a 7° relief angle and a cylindrical hole with a single-sided countersink (40°–60°), allowing secure seating and consistent orientation. These mechanical interfaces simplify tool inventory management and help maintain repeatable cutting conditions across different machines and setups.

Practical system integration and application benefits

Designed for both external and internal turning operations, the insert uses the CM chipbreaker for controlled chip formation when machining cast iron. Its 0.4 mm corner radius supports light to medium finishing passes, producing a reliable surface quality while minimising edge chipping. Integration into a standard system—indexable insert, compatible external holder or boring bar, shim/clamp set and replacement screws—means fast changeovers and straightforward spare-part planning. The result is stable process behaviour, efficient material removal and measurable productivity improvements on the shop floor.
