SCMT120408 T5115 indexable insert for milling (square, 90°) — Tungaloy

The SCMT120408 T5115 is a square indexable insert designed for versatile milling applications, optimised for cast-iron machining and engineered to fit compatible Tungaloy milling systems.

• CVD-coated carbide grade T5115
• Designed for cast iron machining
• 0.8 mm corner radius for durability
• Square shape with 90° cutting angle

Consistent cutting performance for cast-iron work

The CVD-coated carbide matrix of this insert provides a balanced mix of wear resistance and cutting-edge stability, making it especially effective for interrupted or continuous engagement with cast iron. The T5115 grade is formulated for broad material coverage, which reduces the need for frequent tool changes and supports steady cycle times in production. By choosing a universal grade with optimised chip control, process planners gain reproducible surface quality and predictable tool life, which contributes directly to operational efficiency and lower overall machining costs.

Edge security and process reliability under load

A 0.8 mm corner radius and a robust plate thickness of 4.76 mm increase edge strength and reduce the risk of premature chipping during shoulder and high-feed milling. The single-sided chipbreaker geometry helps to form short, controllable chips, improving evacuation when machining grooves or pockets and reducing recutting. Together, these design elements enhance process security and help maintain dimensional stability on successive parts, thereby reducing rework and downtime in medium- to high-volume production.

System compatibility and secure clamping for repeatable results

The insert’s square form and 90° cutting angle suit planing, shoulder and contour milling operations when used in properly matched Tungaloy milling bodies. The insert is supplied with a central hole and a cylindrical hole with one-sided countersink (40°–60°) to ensure positive clamping and consistent seat alignment. This mechanical fit minimises micro-movements during cutting, supporting repeatable positioning and surface finish across batches. Correct pairing of insert geometry and cutter body is essential for maximised tool life and machining performance.

Practical choice for production environments

With a nominal size of 12 mm and a grade optimised for cast-iron applications, this insert represents a pragmatic option for shops seeking a reliable, general-purpose solution. The combination of CVD coating, carbide substrate and engineered chip control enables balanced wear behaviour and good edge retention. If process-specific optimisation is required—such as selection of cutter bodies, speeds or feeds—Metav Werkzeuge can provide tailored advice and machining data to integrate the insert efficiently into existing toolsets.
