Consistent cutting performance for cast-iron turning

The CVD-coated carbide composition of this insert provides a controlled balance between wear resistance and edge stability, which is essential when machining grey and nodular cast iron. The coating reduces abrasive wear and improves thermal resistance, meaning fewer interruptions for index changes and a more predictable tool life. For production environments, this translates into steadier component tolerances and lower overall machining cost per part. The insert’s geometry is optimised to produce short, controllable chips when paired with a suitable double-sided chipbreaker, reducing the risk of built-up edge and enhancing surface finish.

System compatibility that simplifies set-up and repeatability

Designed to the ISO SNMG dimensions, the insert ensures compatibility with standard external holders and boring bars; compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. The square plate form with a cylindrical hole and a 0° relief angle allows straightforward mounting in many ISO clamp systems, shortening set‑up time and helping to reproduce cutting conditions across machines. Clear specification of the plate size and thickness supports engineering decisions for fixture choice and cutting‑force management, enabling consistent results in batch production.

Productivity and edge stability engineered into each grade

The T5115 grade is a universal choice for cast iron, selected to provide a stable cutting edge under varying cutting conditions. The double-sided chipbreaker gives two cutting edges per side, effectively doubling the number of indexable positions and contributing to productive machining cycles. The square geometry with a nominal 90° cutting angle promotes robust engagement on external shoulders and facing operations, allowing higher material removal rates where rigidity permits. Together, these features support efficient cycle times while maintaining component quality.

Practical guidance for selection and application

When choosing this insert, match the insert size, thickness and corner radius to the stiffness of the machine-tool and the clamping system. The 0.8 mm corner radius favours a balance between corner strength and achievable surface finish; larger radii increase edge life but demand higher cutting forces. For finishing passes prefer lower feed and higher spindle stability; for roughing, exploit the robust edge and chip control. If uncertainty exists about holder compatibility or optimal cutting parameters, technical consultation is recommended to align insert grade and chipbreaker to the workpiece material and machining strategy.

FAQ

What materials is this insert best suited for?
The SNMG120408 T5115 insert is formulated as a universal grade for cast iron, offering a balance of wear resistance and edge stability ideal for grey and nodular cast iron applications.

How many usable cutting edges does the plate provide?
With a double-sided chipbreaker on a square SNMG plate, multiple index positions are available; the design permits several usable edges before replacement is required.

Which geometry details should be checked before mounting?
Verify the ISO SNMG 120408 form, 0° relief angle, plate thickness (4.76 mm) and cylindrical hole compatibility with the chosen holder to ensure correct clamping and runout control.

Can this insert be used for both roughing and finishing operations?
Yes; the T5115 grade and the chipbreaker deliver versatility—use higher feeds and depths for roughing and reduce feed for fine finishing to optimise surface quality.

What is the manufacturer article number and SKU for ordering?
The manufacturer article number is 6852987 and the listing SKU is 6852987-Tungaloy for the SNMG120408 T5115 indexable insert.
