SCMT120404 T5115 – ISO square indexable turning insert for turning, Tungaloy

The SCMT120404 T5115 is a CVD-coated carbide ISO turning insert designed for external and internal turning operations, optimised for cast iron with a controlled chipbreaker.

• ISO‑standard square turning insert SCMT120404
• CVD-coated carbide grade T5115
• Designed for cast iron machining
• Cylindrical hole with single-sided countersink

Reliable performance for cast iron machining

The combination of CVD-coated carbide and the T5115 grade provides a balanced mix of wear resistance and edge stability that benefits repetitive turning tasks in cast iron. This geometry and coating reduce flank wear and help maintain cutting edge integrity over longer periods, which in turn supports consistent surface finish and dimension stability. The universal character of the grade allows a pragmatic approach to process planning, reducing the need for frequent insert changes and contributing to predictable cycle times.

Clear mounting and ISO compatibility to simplify tool plans

Supplied in the ISO plate format and a square form, the insert is compatible with standard indexable turning holders when form, clearance, tolerance class, fixing, size and thickness match. The presence of a cylindrical hole with a single-sided countersink (40°–60°) ensures reliable clamping and repeatable seating in the tool body, which reduces setup time and variance between positions. This mechanical clarity supports stable machining and simplifies inventory management for production and maintenance teams.

Geometry that improves cutting reliability and chip control

The insert’s 0.4 mm corner radius and 7° clearance are chosen to deliver a balance between strength and cutting action: the radius helps to absorb cutting forces and avoid premature chipping, while the clearance angle reduces rubbing on the workpiece. The single-sided chipbreaker directs chips for efficient evacuation during external and internal turning, helping to prevent re-cutting and potential surface defects. For operations where chip control is critical, this combination offers a dependable route to fewer interruptions and safer swarf management.

Practical benefits for workshop productivity

By pairing a robust substrate with a modern coating and defined geometry, the insert supports productive machining with predictable tool life and consistent part quality. The square insert shape offers multiple indexing positions, extending effective life per insert and lowering tooling costs in the medium term. Process planners and shopfloor engineers will value the reduced variance between inserts, which helps when programming and verifying turning cycles for everyday production or batch work.

FAQ

What materials is this insert optimised for?
The SCMT120404 T5115 insert is a universal grade optimised for machining cast iron, providing a balanced combination of wear resistance and edge stability for this material group.

Is the insert compatible with standard ISO turning holders?
Yes, the insert follows ISO dimensions; compatibility depends on matching form, free angle, tolerance class, fixing, size and thickness to the chosen holder.

What does the T5115 grade offer compared with other grades?
T5115 is a CVD-coated grade that focuses on a compromise between tool life and edge stability, making it suitable for a wide range of cast iron turning applications.

How does the chipbreaker affect machining?
The single-sided chipbreaker directs chips away from the cutting zone to support secure evacuation, reducing the risk of re-cutting and enhancing surface consistency during turning.

Can the insert be indexed multiple times?
The square geometry allows multiple indexing positions, which extends the effective life per insert and supports economical tooling strategies.
