CNMA 190612 T5115 Turning Insert (CNMA) – 80° Rhombic, CVD Carbide, Tungaloy

CNMA 190612 T5115 is a turning insert designed for external and internal turning, offering a universal carbide grade optimised for cast iron machining

• CVD-coated carbide grade T5115
• Universal grade for cast iron turning
• Rhombic 80° geometry, 1.2 mm nose radius
• Cylindrical hole for secure clamping

Consistent wear resistance for demanding cast iron operations

The CVD-coated T5115 carbide grade combines surface hardness with a stable cutting edge to extend tool life during cast iron machining. This universal grade was developed to provide a compromise between wear resistance and edge stability, which reduces the frequency of index changes in continuous production. As an indexable insert, the design focuses on delivering reproducible cutting results and minimised downtime through predictable wear behaviour and a coating that helps resist built-up edge under typical turning conditions.

Geometry and mounting that support process reliability

The 80° included angle and rhombic shape deliver a versatile cutting geometry suitable for a wide range of turning tasks, while the 1.2 mm nose radius supports both profile accuracy and strength at the cutting edge. Plate dimensions such as 6.35 mm thickness and 19 mm size contribute to stiffness in the assembly. The cylindrical hole provides a secure location for the fixing screw and helps maintain repeatable seating in compatible holders. Holder compatibility is determined by form, clearance angle, tolerance class, fixing, size and thickness, so the matching of insert and clamping system is essential for achieving the advertised performance.

Application guidance and machining advantages

Engineered primarily for turning of cast iron (Gusseisen), the insert is supplied without a chipbreaker, which permits flexible selection of cutting parameters and external chip-control measures depending on the machining task. Inserting the component into a correctly specified external holder or toolpost bar ensures stable cutting, while coolant strategy and feed selection influence surface finish and tool life. The combination of a robust carbide substrate and the CVD layer aims to deliver productive machining with reproducible surface quality, especially in medium to heavy interrupted cuts or continuous finishing passes.

FAQ

Is the insert suitable for cast iron turning?
Yes. The CNMA190612 T5115 insert uses a CVD-coated carbide grade formulated as a universal solution for cast iron, providing a balance of wear resistance and edge stability.

How is the CNMA190612 clamped in the holder?
The insert features a cylindrical hole for screw fastening; correct clamping requires a compatible holder that matches the insert form, clearance angle, tolerance class, size and thickness.

What does the T5115 designation indicate?
T5115 denotes the CVD-coated carbide grade tuned for general cast iron applications, emphasising wear resistance and reliable edge performance for turning tasks.

Can this insert be used for internal turning?
Yes. The geometric design and 80° rhombic shape make the insert suitable for both external and internal turning when mounted in an appropriate internal boring holder.

Does the insert include a chipbreaker?
No. The CNMA190612 is supplied without a chipbreaker, which allows process engineers to select cutting conditions and chip-control strategies suited to the specific operation.
