CCMT 09T312 T5115 — Indexable insert for turning by Tungaloy

A CCMT 09T312 T5115 indexable insert designed for general turning operations, offering a balanced combination of wear resistance and cutting-edge stability for cast-iron machining.

• CVD-coated cemented carbide T5115
• 80° rhombic form with 7° clearance angle
• Optimised for cast-iron turning
• Cylindrical hole with single-side countersink

Robust coating and substrate for longer tool life

The CVD coating on a cemented carbide substrate provides a hard, wear-resistant surface while retaining a tough core to resist chipping. This combination delivers a clear production benefit: longer periods between insert changes and fewer unplanned stoppages. For many turning tasks, the T5115 grade offers an optimal compromise between wear resistance and edge stability, which helps maintain dimensional accuracy and surface finish over extended runs. CVD technology deposits layers that adhere strongly to the substrate, reducing adhesive wear and improving heat resistance during high-temperature cutting cycles.

Geometry designed for reliable chip control and clamping

The 80° rhombic CCMT geometry with a 1.2 mm corner radius and 7° clearance angle yields a versatile cutting profile suited to both light finishing and heavier roughing when combined with the correct chipbreaker. The insert’s cylindrical hole with single-side countersink (40°–60°) ensures secure clamping in compatible holders and stable orientation under load. As the ISO series compatibility depends on form, clearance, tolerance, clamping and thickness, pairing the insert with a matched holder and the right chipbreaker produces predictable chip formation and reduced vibration, resulting in improved surface quality and repeatable component tolerance.

Practical selection and system integration for production environments

This insert is part of the ISO turning insert system and is supplied with a thickness of 3.97 mm and a plate size designation of 09, enabling straightforward replacement in standard indexable-holder setups. Select the one-sided chipbreaker and the T5115 grade specifically for cast-iron applications to benefit from optimised chip control and consistent tool life. Compatibility is determined by the insert form, clearance angle, tolerance class, fixing style, size and thickness; when these factors are matched, the system—insert, holder, clamp and fastening screw—delivers stable machining and predictable process performance in series production.

FAQ

What materials is this insert best suited for?
The T5115 grade is optimised for cast-iron applications; the CCMT geometry and CVD-coated cemented carbide substrate provide balanced wear resistance and edge stability for consistent performance in grey and nodular cast iron turning.

How does the CVD coating improve performance?
CVD coating on the cemented carbide insert reduces adhesive and abrasive wear, increases thermal resistance and extends the effective cutting life of the Tungaloy CCMT09T312 insert under typical turning conditions.

Which holder types are compatible with this insert?
Compatibility depends on the ISO form, clearance angle, tolerance class, fixing style, size and thickness; the CCMT09T312 fits standard ISO external turning holders and boring bars designed for CCMT inserts with matching clamping and thickness.

What is the purpose of the cylindrical hole with countersink?
The cylindrical hole combined with a single-side countersink (40°–60°) ensures secure mechanical fixing, repeatable seating and correct orientation in the clamping system, contributing to stable cutting and accurate repeatability.

How should the chipbreaker and grade be selected for different operations?
Choose the one-sided chipbreaker and the T5115 grade for cast-iron turning; for other materials or alternative machining strategies, select a chipbreaker and grade that match the workpiece material, cutting data and machine/fixture stability to achieve the desired chip formation and surface finish.
