DPMT11T302 T6215 indexable turning insert — rhombic ISO insert for turning (Tungaloy)

The DPMT11T302 T6215 is an ISO‑standard rhombic indexable turning insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Optimised for stainless steel turning
• Rhombic insert with 11° relief angle
• Central hole, cylindrical with 40°–60° countersink

Reliable wear resistance for demanding stainless‑steel turning

The combination of a CVD‑coated carbide substrate and the T6215 grade delivers enhanced wear resistance and consistent edge life when machining stainless steels. The coating reduces flank wear under continuous cutting, while the carbide core sustains thermal and mechanical loads; this results in fewer insert changes and higher uptime. For production environments where batch repeatability matters, the engineered grade supports stable cutting parameters and predictable tool change intervals, translating into measurable productivity gains.

Secure seating and reliable chip control for steady performance

The rhombic geometry and the central cylindrical hole with a 40°–60° countersink ensure a firm and repeatable mounting in compatible holders. The 11° relief angle reduces rubbing on the flank and supports a clean cutting action, while the one‑sided chipbreaker promotes controlled chip formation suited to many stainless variants. The small 0.2 mm corner radius is tailored for finishing passes or light to medium roughing where surface quality and dimensional control are priorities. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; matching these parameters secures the expected performance.

System efficiency and selection guidance for workshop integration

As part of an ISO‑based insert system, this rhombic indexable insert integrates with appropriate external holders or boring bars, a support pad/clamp set and replacement screws to form a reliable cutting assembly. Correct selection of chipbreaker and grade according to workpiece alloy and stability reduces cycle time and improves surface finish. The DPMT11T302 T6215 benefits include straightforward stock keeping through ISO designation, repeatable mounting and suitability for both external and internal turning tasks.

FAQ

What materials is this insert suited for?
The DPMT11T302 T6215 insert is formulated for machining stainless steels; the CVD coating and carbide substrate provide wear resistance and thermal stability when turning common stainless alloys.

How does the hole and countersink affect clamping?
The central cylindrical hole with a 40°–60° countersink ensures secure and repeatable seating in compatible holders, improving positional accuracy and reducing the risk of insert movement under load.

Which features influence surface finish?
Surface finish benefits from the small 0.2 mm corner radius and the insert’s one‑sided chipbreaker; together they enable smoother finishes in finishing passes while maintaining dimensional control.

Is the insert compatible with non‑ISO holders?
Compatibility is determined by insert form, relief angle, tolerance class, fastening type, size and thickness; the ISO designation facilitates matching with standard holders, but verification against the holder specifications is recommended.

Can this insert be used for interrupted cuts?
Yes, the T6215 grade and robust carbide substrate are suitable for stable to light interruptions; for heavy interruptions, assess machining stability and consider alternative geometries or grades.
