SNMG120408 T5115 SNMG Turning Insert — square, 0° clearance — Tungaloy

A SNMG120408 T5115 indexable insert designed for turning operations, offering a CVD-coated carbide grade optimised for cast iron machining and reliable edge stability.

• CVD-coated carbide grade T5115
• Optimised for cast iron machining
• Square 12 mm insert, 0.8 mm corner radius
• 0° clearance with cylindrical hole

Faster, more consistent results on cast iron components

The combination of a CVD-coated surface and a balanced carbide substrate yields predictable wear behaviour and longer effective tool life when machining cast iron. The T5115 grade is formulated to deliver a compromise between wear resistance and cutting-edge stability, which translates into fewer indexings and less production downtime. For workshops aiming to increase throughput, this results in a measurable improvement in process economy and reduced tool-change frequency.

Improved chip control and edge security for stable cuts

Built with a double-sided chipbreaker, the insert provides controlled chip formation across a range of cutting conditions, reducing the risk of re-cutting and securing surface quality. The square geometry and reinforced cutting corner support higher feed rates where rigidity allows, while the 0.8 mm corner radius helps absorb shock loads and prolongs edge life. Together, these attributes create a reliable cutting environment that favours repeatable part quality and reduced scrap rates.

ISO conformity for straightforward tool selection and set-up

As an ISO-designated insert, the shape, clearance angle, tolerance class, fixation and thickness align with common holder systems, simplifying the selection of a matching external holder or boring bar. Explicit attention to the 0° clearance and the cylindrical hole format ensures compatibility with seat and screw types typically used in turning tool systems. This predictability shortens set-up time and facilitates a quicker transition from programming to stable cutting.

Compact dimensions that speed up programming and handling

The insert’s 12 mm nominal size, 4.76 mm thickness and the 0.8 mm corner radius provide compact, robust geometry suitable for both external and internal turning tasks where space and rigidity must be balanced. The square form factor offers up to four indexable edges per insert, improving cost-efficiency per edge compared with single-edge alternatives. Clear, measurable dimensions allow CAM and process engineers to calculate cutting data with confidence, improving cycle-time estimates and tool-life forecasting.

FAQ

Which materials is this insert best suited for?
The SNMG120408 T5115 insert is a universal grade specifically optimised for machining cast iron, offering a balance of wear resistance and edge stability suitable for many grey and nodular cast iron applications.

Is the insert reversible and how many cutting edges are available?
This is a double-sided, square indexable insert providing multiple usable edges; the geometry allows for economical edge usage and quick re-indexing during workshop operations.

How does compatibility with holders and bars work?
Compatibility follows ISO norms for form, clearance and thickness; the SNMG120408 designation and the 0° clearance with cylindrical hole ensure it fits standard external holders and boring bars when matched by seat and fastening specification.

What are the key dimensions to consider when programming or setting up?
Important dimensions are the 12 mm nominal size, 4.76 mm thickness and 0.8 mm corner radius; these values assist in calculating approach, feed and depth parameters for reliable cycle times.

Can the insert be used for internal turning and finishing operations?
Yes, the insert’s geometry and double-sided chipbreaker make it suitable for both external and internal turning; for finishing, choose appropriate feeds and speeds to leverage the grade’s edge stability.
