SNMA 120412 T5115 indexable turning insert by Tungaloy — CVD-coated carbide, for cast iron turning

SNMA 120412 T5115 is an ISO-specification indexable insert designed for external and internal turning in cast iron, combining a universal grade with robust edge stability for consistent production performance.

• SNMA120412 insert, ISO standard
• CVD-coated carbide universal grade T5115
• For cast iron machining with stable edge
• 90° square form with 1.2 mm corner radius

Consistent fit and process reliability through ISO conformity

The SNMA120412 complies with ISO geometry and dimensional tolerances so compatibility with a matching holder is predictable and repeatable. The insert’s specification means that fit is determined by form, clearance angle, tolerance class, fastening method, size and thickness; this reduces setup time and lowers the risk of incorrect tooling combinations. The result is a more stable cutting process and fewer interruptions to production, which supports higher machine utilisation and predictable cycle times.

Balanced wear resistance for cast iron applications

The T5115 grade is a universal CVD-coated carbide developed to provide an even compromise between wear resistance and edge stability when machining cast iron. This balance enables longer tool life on intermittent cuts and helps maintain surface finish on through-feed operations. Where operators require fewer indexings and reliable repeatability, the grade’s combination of coating technology and carbide substrate raises process efficiency and reduces tooling consumption per part.

Robust geometry for accurate, repeatable cutting

A square, 90° insert form with a 1.2 mm corner radius and a thickness of 4.76 mm increases rigidity at the cutting edge and allows stable engagement in both facing and plunge-turning operations. The square form provides four usable corners for economical indexing, while the cylindrical hole supports secure clamping and quick replacement. These design choices minimise vibration, support consistent chip formation, and improve dimensional control on the workpiece.

Seamless integration into existing turning tool systems

This ISO indexable insert is intended to function as part of a complete tooling system — an ISO insert plus a suitable external holder or boring bar, a shim/clamping set and the correct replacement screws. Selecting the appropriate holder that matches form, clearance, tolerance and fastening keeps the cutting edge effective and the process safe. For customers seeking guidance on holder selection or process parameters, technical consultation is available to help align the tool choice with material, machine stability and cycle requirements.

FAQ

Which materials is this insert suitable for?
The SNMA 120412 T5115 indexable insert by Tungaloy is primarily designed for cast iron machining and delivers a balanced combination of wear resistance and edge stability for this material.

What is the corner radius of the insert?
The insert features a 1.2 mm corner radius, giving a compromise between edge strength and the ability to generate the required profile on turned surfaces.

Does this insert include a chipbreaker?
No, this particular insert is supplied without a chipbreaker; chip control should be managed through toolpath, cutting data and holder geometry.

How is compatibility with holders ensured?
Compatibility is achieved by matching the ISO form, clearance angle, tolerance class, fastening method, insert size and thickness; these parameters determine whether a holder and insert form a valid assembly.

How is the insert secured to the holder?
The square insert has a cylindrical hole to accept the correct clamping screw and seating elements; use the manufacturer-recommended clamping set and spare screws for secure fixation.
