CNMA090412 T515 Tungaloy indexable insert for turning — CVD‑coated carbide, rhombic form

The CNMA090412 T515 is an ISO‑standard rhombic indexable insert designed for external and internal turning, optimised for cast iron machining.

• ISO CNMA 090412 rhombic insert
• CVD‑coated carbide grade T515
• Corner radius 1.2 mm for robust cutting
• With cylindrical hole and 80° included angle

Consistent results for cast iron turning

The ISO CNMA090412 geometry provides a predictable contact zone that promotes stable chip formation when turning cast iron. The rhombic shape and corner radius 1.2 mm reduce the risk of edge chipping under interrupted cuts, which leads to longer tool life and fewer insert changes. By choosing a grade matched to workpiece stability and cutting speed, the machining process becomes more cost‑effective: fewer stoppages and consistent dimensional results support higher throughput without compromising surface quality.

Coating and material for reliable wear resistance

A CVD‑coated carbide substrate underpins the insert’s resistance to abrasive wear and thermal loading during continuous turning operations. The T515 grade combines wear tolerance with economy, making it suitable where a balance of performance and cost is required. The coating improves heat management at the cutting edge, which helps to maintain a uniform surface finish and extends the service interval of the cutting edge compared with uncoated grades. This means fewer tool changes and a steadier process in repetitive production runs.

System compatibility for straightforward integration

Compatibility with toolholders is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The insert follows ISO conventions for holders and clamping, enabling straightforward integration into existing tool systems and reducing setup complexity. The presence of a cylindrical hole and the standard plate dimensions facilitate reliable fixation and repeatable positioning, which in turn minimises setup errors and helps to maintain process stability across batches.

Practical guidelines for efficient turning operations

The insert is supplied without a chipbreaker, so the selection of a matching chip control geometry should be considered according to the machining task and material condition. For heavy interrupted cuts or unstable setups the 80° included angle and the 1.2 mm corner radius provide robustness; for finer finishing passes a softer engagement or a smaller radius insert would be appropriate. This indexable solution supports both external and internal turning tasks and is particularly effective when paired with a holder and clamping set suited to the chosen cutting parameters.

FAQ

What materials is this insert best suited for?
The CNMA090412 T515 insert is formulated for economical machining of cast iron; the CVD‑coated carbide offers good wear resistance and chip behaviour for these materials.

Is the insert compatible with standard CNMA holders?
Yes, the insert follows ISO CNMA dimensions and is compatible with holders designed for CNMA 090412 inserts, provided form, clearance and clamping match the holder specifications.

Does this variant include a chipbreaker?
The supplied CNMA090412 T515 insert is without a chipbreaker; chip control should be addressed via holder choice or by selecting an insert grade with integrated chip control where required.

What is the advantage of the 1.2 mm corner radius?
A corner radius of 1.2 mm increases edge robustness under interrupted cuts and enhances tool life in applications where stability and moderate feed rates are required.

How should cutting data be adapted for this grade?
Cutting data should be selected based on workpiece condition and machine stability; the T515 grade supports moderate to high cutting speeds for cast iron while prioritising wear resistance and consistent surface finish.
