SNMG 120408 T5105 turning insert for turning — Tungaloy

The SNMG120408 T5105 is an ISO-compliant square turning insert designed for high-speed machining of cast iron, offering robust wear resistance and precise cutting geometry.

• CVD-coated carbide grade T5105
• Optimised for high-speed machining of cast iron
• Double-sided chipbreaker for flexible use
• 0.8 mm corner radius, 90° cutting angle

Maximise productivity with a wear-resistant cutting grade

The CVD-coated T5105 offers a combination of thermal stability and wear resistance that suits sustained, high-speed operations in cast iron. The CVD-coated surface reduces flank wear and extends edge life, which translates into fewer indexings and longer uninterrupted runs. For production-oriented shops this means higher throughput and lower tooling costs per component, while the consistent edge condition contributes to predictable process windows and stable cycle times.

ISO conformity eases holder selection and setup

As an ISO-compliant turning insert, the component fits a broad range of standard holders when form, clearance angle, tolerance class, fastening and size match. Compatibility is determined by shape, 0.8 mm corner radius, thickness and attachment style, so selecting the correct external holder or boring bar and the matching shim/clamp set is essential. Correct pairing reduces setup time, ensures repeatable clamping and minimises runout-related wear, resulting in improved dimensional accuracy across batches.

Improved chip control and surface quality for efficient turning

The double-sided chipbreaker is engineered to promote consistent chip formation during turning, supporting reliable evacuation in both stable and semi-stable setups. Improved chip control reduces the risk of re-cutting and tool damage, while a maintained cutting edge contributes to a superior surface finish. The square insert form plus the indexable design provides multiple usable edges, enhancing cost-effectiveness per insert and lowering tooling consumption over time.

Recommended applications and process guidance for consistent results

This insert is primarily intended for turning cast iron under stable cutting conditions and at elevated cutting speeds. The 90° cutting angle facilitates general-purpose turning and face-turning operations with predictable tool path behaviour. To exploit the performance of the grade, match the chipbreaker style to the workpiece stability and select a holder suited to the required rigidity; consider a dedicated external holder or boring bar with the appropriate tolerance class and fastening hardware for best outcomes.

FAQ

What materials is this insert best suited for?
The SNMG120408 T5105 insert is optimised for machining cast iron, delivering high wear resistance and thermal stability under high-speed cutting.

How does the chipbreaker affect performance?
The double-sided chipbreaker promotes consistent chip formation and evacuation, improving surface finish and reducing the likelihood of re-cutting.

Is the insert compatible with standard ISO holders?
Yes — the insert is ISO-compliant; compatibility depends on matching form, clearance angle, tolerance class, fastening, size and thickness to the chosen holder.

What does the T5105 grade provide compared with general-purpose grades?
T5105 is a CVD-coated carbide grade selected for enhanced wear resistance at elevated speeds, offering longer edge life in stable cast iron turning operations.

What should be checked when changing to this insert type?
Confirm holder rigidity, correct clamp/shim set, and that the insert form and thickness match the holder’s specifications to ensure reproducible clamping and minimal runout.
