TNMA 110412 T515 ISO turning insert for cast-iron turning — Tungaloy

The TNMA 110412 T515 is a triangular ISO turning insert designed for economical external and internal turning of cast iron, featuring a CVD-coated carbide grade and a 60° included angle.

• CVD-coated carbide grade T515
• Economical machining of cast iron
• ISO TNMA 110412 compatible
• 60° triangle with 1.2 mm radius

Efficient cast-iron turning with predictable tool life

The insert is made from CVD-coated carbide in grade T515, a specification engineered for the economical machining of cast iron. The CVD coating provides a hard, wear-resistant layer that reduces flank wear under interrupted cuts and abrasive microstructure in cast materials. As a result, cycle times remain consistent and tool changes are minimised, which supports efficient batch production. The combination of substrate and coating is described in simple terms: the carbide core gives toughness, the CVD-coated surface increases abrasion resistance — together they extend useful edge life and reduce process costs.

Exact fit and straightforward holder compatibility

Designed to the ISO TNMA 110412 geometrical standard, the insert ensures predictable seating and repeatable positioning in compatible holders. The triangular form with a 60° included angle and a cylindrical centre hole supports secure clamping and simple indexability. Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; therefore matching the insert to the appropriate external holder or boring bar is critical. Metav Werkzeuge can advise on holder choices and clamping options to ensure correct fit and optimal cutting conditions.

Process stability and application guidance without a chipbreaker

This grade is supplied without a chipbreaker, which allows flexibility: the absence of an integral chipbreaker makes the insert suitable for operations where chip control is achieved by the holder geometry, cutting parameters or a separate chipformer. For cast-iron turning, the 1.2 mm corner radius supports a balance between cutting strength and surface finish; select the appropriate radius and cutting data for roughing or finishing to maintain stable cutting forces and consistent surface quality. Choosing the correct feed and depth of cut is decisive for repeatable performance.

Practical benefits in workshop workflows

With a plate thickness of 4.76 mm and a plate size of 11, the triangular turning insert offers a robust cutting edge and multiple indexable corners for economical use. The central cylindrical hole simplifies indexing and reduces setup time when inserts are replaced. Typical uses include both external turning and internal boring where ISO triangular inserts are applicable; the combination of T515 specification and ISO standardisation supports straightforward stock management and predictable replenishment in production environments.

FAQ

What material is the TNMA 110412 T515 insert made from?
The TNMA 110412 T515 insert is manufactured from carbide and finished with a CVD-coated T515 grade to improve wear resistance when machining cast iron.

Is this insert suitable for both external and internal turning?
Yes, the ISO triangular geometry and central cylindrical hole make the insert suitable for both external turning and internal applications where ISO TNMA inserts are accepted.

How does the absence of a chipbreaker affect use?
Supplied without a chipbreaker, the TNMA 110412 T515 requires chip control to be managed by holder design, cutting parameters or an external chipformer, allowing flexibility depending on the machining strategy.

Which corner radius is available and what is it good for?
This insert has a 1.2 mm corner radius, which offers a compromise between edge strength and surface finish and is commonly used for mixed roughing and finishing passes in cast-iron work.
