SCMT 09T312 T5115 — Tungaloy indexable insert for turning, CVD-coated carbide, CM chipbreaker

The SCMT09T312-CM T5115 Tungaloy insert is an ISO-format, square turning insert designed for efficient external and internal machining of cast iron, combining a universal grade with a chipbreaker tuned for stable chip formation.

• CVD-coated carbide T5115
• Optimised CM chipbreaker
• Square 90° insert geometry
• Compatible with ISO holders

High-performance cutting for cast-iron turning

The combination of CVD-coated carbide and the T5115 grade provides a balanced mix of wear resistance and cutting-edge stability that is especially suitable for cast iron machining. The CM chipbreaker is engineered to control chip shape and evacuation, reducing interruptions and minimising the risk of built-up edge. This results in consistent part quality and less unscheduled downtime. The insert’s substrate and coating strategy aim to extend usable life while maintaining edge integrity under typical turning conditions.

Seamless integration with ISO toolholders for straightforward setup

Designed as an ISO-format indexable insert, compatibility depends on the insert’s form, clearance angle (7°), tolerance class, attachment method, size and thickness. The square 90° geometry and the 1.2 mm corner radius offer a stable cutting edge for robust engagement, while the 3.97 mm thickness contributes to rigidity in heavy or interrupted cuts. The plate is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for secure fastening. A typical system comprises an ISO turning insert, a matching external holder or boring bar, a shim/clamp set and replacement screws for quick assembly and precise clamping.

Predictable productivity and economical machining

Selecting the T5115 universal grade with a CM chipbreaker supports a wide material range within the cast-iron family and promotes stable process behaviour, which aids in meeting production targets with repeatable results. The 1.2 mm radius helps deliver the desired surface finish while preserving cutting-edge strength, reducing the need for frequent index changes. Overall, the geometry and coating strategy contribute to lower tooling consumption per part and a more dependable machining routine, making the insert a practical choice for jobbing shops and production environments that require both versatility and consistency.

FAQ

What materials is this insert suited for?
The SCMT09T312-CM T5115 insert is intended primarily for cast iron applications; the T5115 grade balances wear resistance and edge stability for reliable machining of grey and nodular iron.

How does the CM chipbreaker affect performance?
The CM chipbreaker on this indexable insert promotes controlled chip formation and evacuation, improving surface finish and reducing the chance of chip-related interruptions during turning.

Which holders are compatible with this ISO-format insert?
Compatibility requires a holder that matches the insert’s form, clearance angle (7°), size and thickness; the insert works with standard ISO external holders or suitable boring bars when the clamping and tolerance class correspond.

Can the insert handle interrupted cuts?
The square 90° geometry combined with a 1.2 mm corner radius provides edge strength that tolerates many interrupted cut scenarios; selection of cutting data and holder rigidity remains important for optimal performance.

What fastening method does the insert use?
The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for secure fastening in compatible clamping systems and holders.
