CCMT 09T308 T6215 turning insert by Tungaloy — CVD-coated carbide, rhombic 80° form

CCMT09T308 T6215 is a CVD-coated carbide turning insert designed for external and internal turning of stainless steel under stable to lightly interrupted cutting conditions

• CVD-coated carbide grade T6215 for wear resistance
• ISO rhombic CCMT form with 80° included angle
• Single-sided chipbreaker for consistent chip control
• Cylindrical hole with single-side countersink (40°–60°)

Durable grade and productivity gains for stainless steel machining

The T6215 grade is a CVD-coated carbide developed to deliver wear-resistant performance when turning stainless steel under steady or slightly interrupted conditions. The coating improves abrasive resistance and heat tolerance, which reduces flank wear and extends usable life; this leads to fewer indexings and lower tooling cost per component. Where consistent material removal rate and repeatable batch results are required, the combination of substrate and coating provides a predictable tool life that supports continuous production.

ISO compatibility and secure mounting for predictable results

Designed as an ISO CCMT09T308 insert, the geometry is rhombic with an 80° included angle and a 7° clearance, ensuring compatibility with standard CCMT holders when form, clearance, tolerance class, fastening, size and thickness match. The insert features a cylindrical hole with a single-side countersink (40°–60°) to suit common clamping systems. These mechanical details simplify integration into existing toolholders and minimise setup variability, contributing to stable cutting conditions and reproducible component quality.

Chip control and surface quality with a single-sided chipbreaker

The single-sided chipbreaker geometry is tailored to promote stable chip formation and evacuation in turning operations. By pairing the chipbreaker with the appropriate grade and cutting parameters, the tool supports improved surface finish and reduced risk of built-up edge when machining stainless steels. The controlled chip flow also reduces the likelihood of re-cutting, helping to protect the workpiece surface and preserve dimensional accuracy during longer cycles.

Practical dimensions and mechanical strength for everyday use

With a nominal size of 09, a plate thickness of 3.97 mm and a corner radius of 0.8 mm, the insert balances rigidity with cutting edge definition. The 0.8 mm corner radius offers a compromise between edge strength and surface finish capability, suitable for general turning tasks where durability and acceptable finish are required. Integration into a typical system—insert, compatible external holder or boring bar, shim/clamp set and replacement screws—ensures straightforward maintenance and fast index changes at the machine.

FAQ

What workpieces is this insert best suited to?
The CCMT09T308 T6215 insert is optimised for machining stainless steel under stable to slightly interrupted cutting conditions, offering good wear resistance and chip control for typical turning applications.

How does the T6215 grade improve process reliability?
The T6215 CVD-coated carbide provides improved abrasive resistance and thermal stability, which extends tool life and supports consistent batch-to-batch performance when used with the correct cutting data.

Which holder features ensure correct compatibility?
Compatibility requires a matching CCMT holder regarding form, clearance angle, tolerance class, fastening method, size and plate thickness; the rhombic geometry and hole style are standard for CCMT applications.

What is the effect of the 0.8 mm corner radius on machining?
A 0.8 mm corner radius increases edge strength, reduces chipping risk and contributes to stable cutting forces, while still allowing acceptable surface finish for general turning tasks.
