SNMG120412 T5115 ISO turning indexable insert — Tungaloy

SNMG120412 T5115 is an ISO‑standard square insert for turning operations, engineered for cast iron machining with a balanced mix of wear resistance and cutting-edge stability.

• CVD-coated carbide grade T5115
• Square ISO insert with 90° cutting edge
• Double-sided chipbreaker for consistent chips
• Cylindrical hole for reliable clamping

Stable cutting performance for cast-iron turning

The SNMG120412 T5115 insert brings CVD-coated carbide performance to demanding turning tasks, delivering a reliable balance between wear resistance and edge stability. The coating enhances resistance to abrasive wear typical for grey and nodular cast iron, while the substrate provides toughness at interrupted cuts. The combination reduces tool changes and improves process consistency, making this insert suitable for shopfloor environments where reproducible results and predictable tool life are required.

Secure clamping and chip control that improve uptime

A cylindrical hole and the double-sided chipbreaker design ensure positive seating and controlled chip formation during external and internal turning. The square geometry with 90° main cutting angle provides robust support at the corner, while the 1.2 mm corner radius contributes to edge strength and surface finish. These features lower the risk of edge chipping and reduce unexpected downtime, supporting efficient production cycles and straightforward insert indexing to the next cutting edge.

Compatibility and practical handling for workshop integration

ISO compliance and the specified dimensions (12 mm size, 4.76 mm thickness) simplify selection of matching holders and bar tooling: compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness. The neutral 0° relief angle gives a standard geometry for versatile cutting approaches. The insert’s universal grade is particularly suited to cast-iron applications but can be evaluated against other materials depending on machining parameters and workpiece stability. Documentation of holder fit and clamping torque is advised to achieve the best performance.

FAQ

What material is this insert best suited for?
The SNMG120412 T5115 insert is formulated for cast iron machining; the T5115 grade provides a balanced combination of wear resistance and cutting-edge stability for such materials.

How does the chipbreaker benefit production?
The double-sided chipbreaker on this insert secures consistent chip formation and evacuation, supporting uninterrupted cycles and reducing the risk of built-up edge.

Is the insert compatible with standard ISO holders?
ISO standard dimensions (size 12, thickness 4.76 mm, cylindrical hole) facilitate compatibility; holder fit depends on form, clearance, tolerance class, fastening and thickness.

How many cutting edges are available per insert?
The two-sided design allows indexing to the opposite cutting edge, effectively extending usable life compared with single-sided variants.

What is the corner radius significance?
The 1.2 mm corner radius increases edge toughness for interrupted cuts and contributes to improved surface finish and tool life under stable machining conditions.
