CPMT 090308 T6215 Turning insert — Tungaloy

The CPMT090308 T6215 is an ISO-standard rhombic turning insert designed for reliable external and internal turning of stainless steels under stable to slightly interrupted cutting conditions.

• ISO rhombic insert CPMT 090308
• CVD-coated carbide grade T6215
• Single-sided chipbreaker for stable chips
• With hole and single-side countersink

Improved tool life and consistent surface results

The CVD-coated carbide T6215 grade offers enhanced wear resistance and temperature tolerance, which translates into extended cutting edge life and fewer tool changes. For machining stainless steels, the coating reduces flank wear and helps maintain a consistent surface finish even during prolonged runs. CVD (chemical vapour deposition) layers form a hard outer film that protects the substrate carbide while preserving edge precision; this means fewer interruptions, lower tooling costs per component and stable process windows in series production.

Predictable fit and secure clamping in ISO systems

Designed to the ISO turning insert family, the rhombic geometry and standardised dimensions ensure predictable compatibility with matched holders. Key geometry features such as the 11° relief, 80° included angle and 3.18 mm plate thickness combine to give a rigid cutting edge and reliable seating in the clamping system. The insert’s hole—cylindrical with a single-side countersink (40°–60°)—provides secure fixing and repeatable positioning. These characteristics simplify holder selection and reduce setup variability in the machine shop.

Chip control and process stability on the shop floor

The single-sided chipbreaker is tuned for stable to lightly interrupted cuts, promoting controlled chip formation when turning stainless steels. Effective chip control reduces risk of surface damage and tool re-cutting, shortening cycle times and lowering scrap rates. The moderate corner radius (0.8 mm) balances edge strength with the ability to produce fine surface finishes. For varied workpiece conditions, pairing the insert’s chipbreaker and grade with a suitable holder and cutting parameters leads to measurable productivity gains and consistent component quality.

FAQ

Which materials is this insert intended for? The CPMT090308 T6215 insert is optimised for machining stainless steels, offering wear resistance and thermal stability for stable turning operations.

What does the CVD coating provide in practice? A CVD-coated surface on the insert reduces flank wear, improves heat resistance and helps maintain cutting-edge geometry, resulting in longer tool life and steadier surface quality for the CPMT090308 T6215.

How does the insert ensure compatibility with holders? Compatibility is achieved through the ISO-standard geometry: the rhombic form, 11° relief, standard size designation and the specified thickness ensure predictable seating and clamping with matching external holders and boring bars.

Can the insert handle interrupted cuts or heavy cuts? The single-sided chipbreaker is aimed at stable to slightly interrupted cuts; for heavy or highly interrupted machining, selection of a different chipbreaker or tool grade may be preferable.

What are the manufacturer references for ordering? Manufacturer article number 6876409 and the manufacturer SKU TUN6876409 identify the CPMT090308 T6215 insert for procurement and ordering purposes.
