TPMT 130308 T6215 TPMT — Turning insert, CVD-coated carbide, 0.8 mm radius — Tungaloy

A TPMT130308-PSS T6215 ISO-format turning insert engineered for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide grade T6215
• PSS chipbreaker for stainless-steel turning
• 0.8 mm corner radius for finishing
• ISO 130308 triangular insert, 3.18 mm thick

Consistent tool life with a wear-resistant CVD coating

The combination of a CVD-coated surface and a specially formulated carbide matrix gives the insert a wear-resistant edge suited to prolonged production runs when machining stainless steel. The PVD/CVD layer reduces abrasive wear and helps maintain cutting geometry over repeated indexings, which leads to fewer unplanned tool changes and more predictable cycle times. For operations where tool life and process consistency are priorities, this geometry and coating deliver measurable improvements in uptime.

Geometry and clamping designed for secure, repeatable positioning

The triangular ISO form (ISO 130308) with a 60° included angle and 11° relief provides both rigidity and easy indexability. The 0.8 mm radius balances edge strength with the ability to achieve fine surface quality in finishing passes. The insert is 3.18 mm thick and includes a cylindrical hole with a one-sided countersink (40°–60°), ensuring firm clamping in compatible holders and boring bars. Clear attention to tolerance and clamping design translates to repeatable seating and reduced vibration across batches.

Predictable chip control for improved surface finish and process stability

Equipped with the PSS chipbreaker, the insert promotes controlled chip formation when turning austenitic and other stainless steels, reducing the risk of long, stringy chips that interfere with workpiece handling. Controlled chip flow contributes directly to a better surface finish, safer chip evacuation and less downtime for manual clearing. Where stable cutting conditions exist, the chipbreaker supports consistent part quality and simplifies downstream cleaning and inspection.

System-level compatibility and practical application guidance

The insert functions as part of a system: an ISO-format insert seated in a compatible external holder or boring bar, with the correct shim/clamping set and replacement screws. Compatibility depends on form, relief angle, tolerance class, clamping design, size and thickness; verify these dimensions when selecting a holder. Typical applications include external and internal turning where stable set-up and moderate interruptions occur. The material designation and chipbreaker choice make this insert a pragmatic option for shops seeking repeatable performance on stainless components.

FAQ

What steels is this insert intended for? The TPMT130308-PSS T6215 insert is intended primarily for machining stainless steels, with the T6215 grade offering wear resistance under stable to lightly interrupted turning.

How does the PSS chipbreaker improve machining? The PSS chipbreaker on this insert promotes controlled chip formation during turning of stainless steels, aiding chip evacuation and contributing to a more consistent surface finish with fewer interruptions.

Which holder types are compatible with this insert? Compatibility requires matching the ISO 130308 form, relief angle, tolerance class, clamping style, size and thickness; the insert is designed for use in standard external holders or boring bars that accept triangular ISO inserts.

Can the insert be used for interrupted cuts? The T6215 grade and PSS chipbreaker are suitable for stable to lightly interrupted cutting conditions; for heavy interruptions a different geometry or grade may be preferable.

What ensures repeatable seating and reduced vibration? The combination of the cylindrical hole with one-sided countersink (40°–60°), correct thickness and ISO form improves clamping stability and repeatable seating, which reduces vibration and improves part quality when used in a compatible holder.
