CNMA 190612 T5125 Wendeplatten - Tungaloy

Combining a CVD-coated carbide T5125 grade with the CNMA190612 geometry and an 80° included angle yields a robust solution for interrupted turning of cast iron; the rhombic form and 1.2 mm corner radius support consistent edge life and reliable chip control under less stable conditions.

CNMA 190612 T5125 Turning insert (ISO) by Tungaloy — rhombic 80° geometry, CVD-coated

CNMA190612 T5125 Tungaloy insert designed for ISO-standard turning applications, offering a tougher CVD-coated carbide for interrupted cuts and less stable setups

• CVD-coated carbide grade T5125 for toughness
• ISO CNMA190612 rhombic insert, 80° included angle
• 1.2 mm corner radius for robust edge strength
• Cylindrical-hole fixing; 6.35 mm plate thickness

Consistent performance for interrupted turning

The CVD-coated carbide composition of this indexable insert is formulated as grade T5125, which gives a tougher cutting edge suitable for cast iron and operations with interrupted cuts. The rhombic geometry with an 80° included angle provides a favourable balance between strength and accessibility, reducing the risk of edge chipping when machining unstable setups. In practice, this means a steadier cycle time and fewer unplanned tool changes, supporting higher uptime in serial production.

Secure interface and simple integration with holders

Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic insert is supplied with a cylindrical hole to enable positive clamping in standard ISO CNMA pockets. The 6.35 mm plate thickness and standard sizing simplify selection of a matching outer holder or boring bar, while shims and clamping sets provide the correct seating and repeatability. Where interrupted turning is frequent, selecting the corresponding holder and clamping kit ensures stable cutting conditions and repeatable part quality.

Material suitability and process advantages

This grade is optimised for cast iron applications and less stable cutting conditions: the tougher carbide substrate resists edge fracture and tolerates shock loads better than more wear-focused grades. With a 1.2 mm corner radius, the cutting edge delivers improved load distribution and enhanced edge life on roughing passes, while the absence of an integrated chipbreaker makes the insert suitable for applications where manual chip control or specific coolant strategies are used. Overall, the combination of CVD coating and geometry supports predictable tool life and consistent surface finish, contributing to efficient material removal and lower overall machining costs.

FAQ

What materials is this insert best suited for?
The CNMA190612 T5125 Tungaloy insert is optimised for cast iron machining and performs reliably in interrupted cutting where a tougher grade is required.

Can this insert be used in standard CNMA holders?
Yes — compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the rhombic shape and cylindrical hole of this insert suit standard ISO CNMA pockets when the correct clamping set and shim are used.

Why choose grade T5125 for this geometry?
Grade T5125 combines a tougher substrate with a CVD coating, reducing the risk of edge fracture during interrupted cuts and in less stable clamping conditions, which extends productive tool life.

Is there an integrated chipbreaker on this insert?
This variant is supplied without a chipbreaker, so chip control relies on process parameters, toolpath strategy and coolant application rather than an integral chipbreaker geometry.

What is the manufacturer article number and SKU for ordering?
Manufacturer article number 6850174, available under SKU TUN6850174 for the CNMA190612 T5125 Tungaloy turning insert.
