CNMG 160608 T5115 — ISO turning insert for turning applications, Tungaloy

The CNMG160608 T5115 is an ISO‑standard rhombic insert made for external and internal turning, optimised for cast‑iron machining with a balance of wear resistance and edge stability

• ISO‑compliant CNMG 160608 geometry
• CVD‑coated carbide grade T5115
• Balanced wear resistance and edge stability
• Double‑sided chipbreaker with cylindrical hole

Precision geometry that eases setup and increases uptime

The rhombic 80° geometry and 0° clearance ensure a predictable tool path and stable contact with the workpiece. The insert’s 0.8 mm corner radius and 6.35 mm thickness contribute to robust edge strength and resistance to chipping, which in turn reduces unplanned tool changes and improves process reliability. As an ISO‑conforming insert, it fits into standard CNMG‑type toolholders provided the holder matches the insert form, tolerance and clamping arrangement; this compatibility simplifies inventory and shortens changeover times. The result is a measurable reduction in machine idle time through consistent repeatability.

Coating and grade designed for cast‑iron productivity

The CVD‑coated carbide composition in grade T5115 is formulated as a universal choice for cast iron, providing a compromise between abrasion resistance and cutting‑edge stability. The coating enhances thermal and chemical resistance, extending tool life in heavy interrupted cuts and continuous production runs. Stable chip formation is supported by the double‑sided chipbreaker, which maintains efficient evacuation and reduces heat buildup at the cutting edge. For workshops seeking steady surface quality and predictable wear behaviour, this insert offers a cost‑effective route to lower per‑part tooling costs.

Practical system considerations for reliable machining

In a typical setup the ISO insert is paired with a matching external holder or boring bar plus a shim or clamp kit and spare screws to form the complete system. Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness, so holders should be selected to match these parameters exactly. The insert’s cylindrical hole enables secure clamping and straightforward indexing when the edge is refreshed. For both roughing and finishing passes in cast iron, the combination of geometry and grade reduces vibration sensitivity and supports predictable cycle times.

Productivity benefits and recommended applications

The insert excels in external and internal turning operations where cast iron is the primary workpiece material; its universal grade allows use across a broad range of grey and ductile cast‑iron grades. The balance of wear resistance and edge strength helps maintain dimensional stability over longer tool lives, supporting higher process yields and fewer interruptions. Where higher cutting forces or interrupted cuts are expected, the robust 6.35 mm body and rhombic form provide the mechanical support required for stable cutting. For series production, the repeatable performance of this ISO insert contributes directly to throughput and part quality.

FAQ

What applications suit this insert best?
The CNMG160608 T5115 insert is intended primarily for external and internal turning of cast iron, where its CVD‑coated carbide grade T5115 offers a balanced combination of wear resistance and edge stability.

How is the insert clamped and indexed?
The insert is provided with a cylindrical hole for secure clamping and is double‑sided to allow indexing of the cutting edges; compatibility with holders depends on matching the ISO CNMG geometry and thickness.

Can the insert be used for finishing passes?
Yes — the geometry and 0.8 mm corner radius support finishing where a robust edge and good surface quality are required; choose cutting parameters and holder rigidity to match the desired surface finish.

Which materials are recommended for use with this grade?
The T5115 grade and CVD coating make the insert suitable for a broad range of cast‑iron materials, delivering stable chip formation and consistent wear behaviour in production turning.

Is the insert supplied as a single piece or in kits?
The item is offered as a single ISO insert (CNMG160608 T5115); tool systems typically require the matching external holder or boring bar plus a shim/clamp set and screws, which can be supplied separately.
