CNMA190612 T515 turning insert by Tungaloy — CVD-coated carbide, 80° rhombic

A CNMA190612 T515 turning insert designed for economical turning of cast iron in ISO-standard tool systems

• CVD-coated carbide for extended tool life
• ISO rhombic CNMA form, 80° cutting angle
• 1.2 mm corner radius for robust finishes
• Designed for economical cast iron turning

Proven performance for productive turning

The CVD-coated grade T515 combines wear-resistant layers with a tough carbide substrate to deliver consistent edge life when machining grey and nodular cast iron. The coating reduces flank wear and maintains the cutting geometry over longer runs, which improves process stability and lowers tool-cost per component. For establishments aiming to raise throughput, the result is fewer indexings and predictable tool-change intervals, supporting continuous production with measurable efficiency gains.

System compatibility and secure clamping

Built to the ISO CNMA family, this rhombic insert fits common 80° turning holders; compatibility is governed by form, relief angle and nominal size. The plate thickness of 6.35 mm and the designated with hole (cylindrical hole) make mechanical locating and clamping straightforward in standard holders and boring bars. The nominal size 19 mm matches ISO sizing conventions, which simplifies tooling procurement and reduces the need for adapter kits when integrating the insert into existing tool systems.

Application guidance and cutting behaviour

With a 1.2 mm corner radius, the geometry balances edge strength and surface finish: larger radii support interrupted cuts and roughing passes, while still permitting a controlled finish where stability allows. The grade is optimised specifically for cast iron turning; absence of an integrated chipbreaker recommends pairing the insert with a holder or cutting strategy adapted to chip control, depending on workpiece form and stability. Selecting the correct cutting data and clamping setup will exploit the CVD coating’s thermal and abrasive resistance for best results.

Handling, stock and selection tips

The rhombic plate shape and 80° cutting angle offer versatility for both external and internal turning tasks, reducing the number of plate geometries needed in a tooling bin. As the insert is supplied to ISO dimensions, replacement and stock rotation are simplified. For interrupted cuts or unstable setups, choose a higher-stability holder and consider smaller depth-of-cut increments to protect the cutting edge.

FAQ

What materials is this insert best suited for?
The CNMA190612 T515 insert is optimised for cast iron turning; the CVD-coated T515 grade provides abrasion and thermal resistance suited to graphite-containing materials.

Will the plate fit existing ISO CNMA holders?
Yes, the CNMA190612 conforms to ISO CNMA dimensions and works with holders that accept 19 mm CNMA plates with a 6.35 mm thickness and cylindrical locating hole.

How does the 1.2 mm corner radius affect machining?
A 1.2 mm radius increases edge strength for interrupted cuts and roughing, improving stability and reducing premature chipping compared with finer radii.

Is a chipbreaker included with this insert?
This grade is supplied without a chipbreaker; chip control should be achieved via holder geometry, cutting parameters or an appropriate clamping strategy.

What does the "with hole" designation mean for mounting?
The plate’s cylindrical hole provides positive mechanical location and secure clamping with standard CNMA clamping sets.
