CCMT 09T312 T6215 – Tungaloy indexable insert for turning (CVD-coated carbide, 1.2 mm radius)

The CCMT09T312 T6215 is an ISO-standard rhombic indexable insert designed for precise external and internal turning, especially suited to rostfreier Stahl under stable to mildly interrupted cutting conditions

• CVD-coated carbide for high wear resistance
• 1.2 mm corner radius for robust finishes
• Rhombic ISO 09 geometry, 80° shape
• Cylindrical hole with 40°–60° countersink

Optimised performance for rostfreier Stahl turning

The CVD-coated grade T6215 delivers wear resistance and consistent cutting behaviour when machining rostfreier Stahl, reducing the frequency of insert changes and unplanned downtime. This indexable insert combines a hard coating with a tough carbide substrate to balance edge stability and longevity, giving a measurable improvement in productive cutting time. Choosing this grade supports predictable tool life under stable or lightly interrupted conditions and contributes to lower unit costs through fewer replacements.

Secure clamping and precise geometry for consistent surface quality

A carefully defined geometry ensures repeatable results: the 1.2 mm corner radius helps avoid premature flank wear while maintaining acceptable surface finish and strength at the cutting edge. The insert’s rhombic form with an 80° shape and a 7° relief angle stabilises contact with the workpiece and simplifies seat alignment in indexed holders. The cylindrical hole with single-sided countersink (40°–60°) ensures reliable clamping force and repeatability, while the 3.97 mm thickness contributes to stiffness during heavy cuts. These characteristics reduce vibration and support consistent dimensional accuracy across batches.

Economic advantages and system compatibility for production environments

Operating to ISO standards, this insert integrates into common insert-holding systems where compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The grade’s balanced substrate and coating promote stable chip formation and longer tool life, which in turn lower tool-change frequency and increase overall throughput. When used as part of a complete system—insert, appropriate external holder or boring bar, clamp set and replacement screws—the result is a predictable machining process that supports both small-batch flexibility and sustained serial production.

FAQ

Which materials is this insert intended for?
The Tungaloy CCMT09T312 in grade T6215 is designed primarily for machining rostfreier Stahl, offering a balance of wear resistance and edge stability for that material class.

Can the insert be used for internal turning operations?
Yes, the ISO rhombic geometry and available holder systems make the insert suitable for both external and internal turning tasks when mounted in an appropriate boring bar or holder.

What are the key dimensions to check before ordering holders?
Check corner radius (1.2 mm), insert size (09), thickness (3.97 mm), relief angle (7°) and the 80° shape to ensure the holder matches the insert’s seating and clamping requirements.

How does the hole and countersink affect clamping?
The cylindrical hole with a single-sided countersink (40°–60°) provides precise centring and secure fastening in compatible clamping systems, improving repeatability and resistance to cutting forces.

Is the insert supplied as part of a system or individually?
The CCMT09T312 is supplied as an indexable insert; a matching external holder or boring bar, clamp set and replacement screws are required for a complete system and must be selected to the ISO seat specifications
