Better chip control and consistent edge life for cast iron

The combination of the T5115 grade and CVD‑coated carbide provides a balanced mix of wear resistance and edge stability that is well suited to cast iron machining. The single‑sided chipbreaker promotes predictable chip formation, reducing the risk of built‑up edge and improving surface quality on the workpiece. For production environments, this means fewer interruptions for tool changes and more consistent component dimensions, translating into higher process efficiency and lower overall cost per part.

Secure fit and ISO compatibility for repeatable set‑ups

Designed to the ISO dimensioning system, the insert matches standard holders by form, free angle and tolerance class; features such as the 7° relief, 4.76 mm thickness and the central hole with a cylindrical bore plus one‑sided countersink ensure reliable clamping. This ISO compatibility reduces set‑up time and improves repeatability across multiple machines. The standardised geometry also simplifies inventory management in mixed‑brand toolrooms, helping to maintain steady production flow.

Geometry and radius for stability and surface finish

The rhombic 80° geometry combined with a 0.8 mm corner radius delivers a compromise between cutting edge strength and the ability to produce a fine surface finish. In roughing passes the corner radius increases resistance to chipping, while in light finishing it supports good workpiece appearance when combined with the correct cutting data. Where rigidity is limited, the insert’s geometry contributes to process security and predictable tool life, supporting productive machining strategies without sacrificing component quality.

FAQ

Is this insert suitable for finishing cast iron components?
Yes. The CCMT120408 T5115 turning insert is a universal grade for cast iron that combines T5115 CVD coating and a chipbreaker designed to produce controlled chips and an improved surface finish.

Can the insert be used in standard ISO toolholders?
Yes. The insert follows ISO dimensions and its form, free angle and tolerance class are compatible with standard ISO‑matched holders for secure clamping and repeatable set‑ups.

What does the 0.8 mm corner radius mean for machining stability?
A 0.8 mm corner radius increases edge strength for interrupted cuts and improves dimensional stability, making the insert suitable for both stable roughing and light finishing passes.

How does the single‑sided chipbreaker affect chip formation?
The single‑sided chipbreaker on this indexable insert promotes predictable chip curling and evacuation, reducing the risk of tangling and helping to maintain uninterrupted production cycles.

What is the SKU and manufacturer for ordering?
The SKU is 6864293‑Tungaloy and the insert is supplied by Tungaloy; reference this when enquiring about availability or compatibility.
