SNMA 120412 T515 indexable insert for turning by Tungaloy

A SNMA120412 T515 ISO‑format indexable turning insert optimised for economical machining of cast iron with a 1.2 mm corner radius and a 90° approach angle.

• CVD-coated carbide T515 grade
• ISO SNMA120412 square geometry
• 1.2 mm corner radius for fine finishing
• Suitable for cast iron turning

Higher throughput with predictable tool life

The combination of a CVD‑coated carbide substrate and grade T515 delivers a reliable balance between wear resistance and economy when machining cast iron. The CVD coating forms a hard, chemically stable outer layer that reduces abrasive wear and helps maintain cutting edge integrity at elevated cutting speeds; this yields longer intervals between indexings and fewer unplanned stoppages. As a result, shop floors see improved cycle times and a reduced cost per component without compromising surface quality.

Secure clamping and straightforward holder matching

The ISO SNMA120412 geometry, square form and the central cylindrical hole ensure consistent seating and clamping in compatible external holders or boring bars. With a plate thickness of 4.76 mm and a clear designation, setup becomes repeatable and tolerant to small positional deviations, reducing changeover time. Clear ISO compatibility aids quick tool changeovers and predictable machining behaviour in serial production.

Edge technology for stable chip formation

The toolgrade and coating combination gives enhanced edge stability during continuous turning. The 1.2 mm corner radius provides a robust cutting edge suitable for fine finishing passes, lowering the risk of edge chipping under moderate interruptions. Selecting an appropriate chipformer or chipbreaker remains important for efficient evacuation; the grade is optimised for broad cast‑iron coverage but the absence of an integrated chipbreaker in this variant means chip control should be considered at the holder level.

Practical advantages for workshop operation

Using an ISO‑format indexable insert supports fast indexing and straightforward inventory management: identical inserts fit a range of holders conforming to the SNMA form, simplifying stocking and supply logistics. The 90° approach angle offers neutral cutting force direction for many turning operations, aiding dimensional stability. If uncertainty exists about holder compatibility or process parameters, Metav Werkzeuge can advise on the best combination of holder, clamping set and cutting data to match production priorities.

FAQ

Which materials suit this insert best?
The SNMA120412 T515 insert is primarily designed for economical machining of cast iron; the T515 grade and CVD coating provide good wear resistance for grey and nodular cast irons while preserving surface finish.

How is the insert secured in the holder?
The ISO SNMA120412 geometry and central cylindrical hole enable reliable clamping in compatible external holders or boring bars, with the 4.76 mm thickness ensuring stable seating.

What cutting edge preparation and angle are provided?
The insert features a 1.2 mm corner radius and a 90° approach angle, offering a robust edge for finishing passes and neutral cutting forces for many turning tasks.

Is the SNMA120412 suitable for interrupted cuts?
The T515 grade is geared toward economical cast‑iron turning; for heavily interrupted cuts, overall system rigidity and holder choice should be evaluated to ensure edge life and process stability.
