DNMA 150412 T5115 ISO turning insert for turning applications by Tungaloy — CVD-coated carbide, rhombic 55°

The DNMA150412 T5115 is a rhombic ISO turning insert designed for efficient external and internal turning of cast iron components, offering a balance of wear resistance and cutting-edge stability.

• CVD-coated carbide grade T5115
• Optimised for cast iron machining
• 55° rhombic geometry for stable cutting
• 1.2 mm corner radius for secure edge retention

High-performance cutting that extends tool life

The CVD-coated carbide grade T5115 combines wear resistance with a robust cutting edge to deliver consistent results in cast iron turning. This universal grade is formulated to balance edge stability and abrasion resistance, which reduces flank wear and extends productive life. For shops seeking repeatable surface quality, the benefit is fewer index changes and more uptime, translating directly into improved throughput and lower tool-related disruptions.

Reliable seating and predictable compatibility with ISO holders

The ISO-standardised geometry ensures that the insert mates predictably with a matching external holder or boring bar; compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness. The rhombic shape with a cylindrical mounting hole supports secure clamping and repeatable positioning. Specifying components that match these parameters simplifies toolholding decisions and reduces the risk of runout or improper seating during setup.

Stable cutting performance for consistent part quality

A 55° geometry combined with a 1.2 mm corner radius provides a favourable compromise between cutting force distribution and edge strength, helping to maintain dimensional accuracy and surface finish during interrupted cuts or varying depth of cut. Where process stability is required, the insert’s form helps minimise vibration and supports steady chip formation, which in turn improves overall process security and reduces scrap rates in serial production.

Practical recommendations for selection and system setup

Select the appropriate chipbreaker and grade to match the workpiece material, machining type and machine-tool rigidity; the right combination optimises chip control and tool life. The complete system typically comprises the ISO insert, a compatible holder or boring bar, underlay/clamping set and replacement screws. Where uncertainty remains about holder matching or optimal parameters for a given operation, technical advice is recommended to ensure efficient integration into existing tooling systems.
