SNMA120408 T5115 — SNMA indexable turning insert for turning, CVD-coated cemented carbide by Tungaloy

A SNMA120408 T5115 indexable insert designed for ISO-compliant external and internal turning, optimised for cast iron machining and stable production cycles

• CVD-coated cemented carbide for durability
• Universal grade T5115 for cast iron machining
• Square 12 mm insert, 4.76 mm thick
• 0.8 mm corner radius and 90° geometry

Higher output through process-stable cutting performance

The combination of a CVD-coated surface and cemented carbide substrate ensures consistent cutting behaviour and extended edge life in serial turning. The T5115 grade balances wear resistance and edge stability, reducing unplanned tool changes and improving machine utilisation. For practical terms: the coating increases resistance to abrasive wear common in cast iron, while the carbide core maintains rigidity under interrupted cuts, translating into fewer stoppages and steadier component quality.

Seamless integration into ISO tool systems saves setup time

Designed as an ISO-compliant turning insert, the plate fits standard holders when form, clearance angle and tolerance class match. The 12 mm size and 4.76 mm thickness conform to common clamping systems, while the cylindrical hole enables secure screw fixing. This standardised form factor simplifies inventory management and reduces adapter requirements, enabling quicker changeovers and predictable tool performance across different lathes and setups.

Tailored grade and geometry for cast iron applications

As a universal option for cast iron, the T5115 grade provides a pragmatic balance between flank wear control and edge robustness. The insert is supplied without a chipbreaker, giving the operator freedom to select the most suitable chip control item for the workpiece and cutting conditions. The 0.8 mm corner radius and 90° insert geometry support stable engagement and good surface integrity when turning common grey and nodular cast irons.

Robust design for repeatable production quality

The square form and central cylindrical hole offer reliable clamping and the potential for multiple indexings, extending usable life per insert. In repetitive production, this leads to improved repeatability and consistent component tolerances. The insert’s compatibility with ISO turning systems also facilitates predictable process planning, making it a practical choice for workshops seeking a balance of economy and consistent results with cast iron components.

FAQ

What materials is this insert best suited for?
The SNMA120408 T5115 insert is a universal option optimised for cast iron; the T5115 grade and CVD-coated cemented carbide substrate provide a balance of wear resistance and edge stability suited to grey and nodular cast irons.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO geometry conventions; compatibility depends on holder form, free angle, tolerance class, clamping method, size and thickness — the SNMA120408 is a 12 mm square insert, 4.76 mm thick.

Does the insert include a chipbreaker?
This particular variant is supplied without a chipbreaker, allowing selection of a matching chip control accessory to suit the specific cast iron grade and cutting strategy.

How many edges can be used before replacement?
Edge count depends on cutting conditions and material; the square SNMA120408 typically offers multiple indexings, and the T5115 grade aims to extend usable life through balanced wear properties.

What clamping method does the insert require?
The insert uses a central cylindrical hole for screw clamping in compatible ISO-style holders, ensuring secure retention and repeatable positioning
