DCMT11T302 T6215 — ISO turning insert, CVD-coated carbide by Tungaloy

A DCMT11T302 T6215 indexable insert designed for external and internal turning of stainless steels under stable to lightly interrupted conditions.

• DCMT 11T302 T6215 CVD-coated carbide
• Designed for turning stainless steels
• Rhombic shape with 55° cutting angle
• 0.2 mm corner radius, 7° relief angle

Durable coating and material for reliable stainless-steel machining

The CVD-coated T6215 grade combines a wear-resistant surface layer with a tough carbide substrate to reduce flank and crater wear during continuous cuts. This coating helps to resist adhesive wear and the typical tendency for stainless steels to form built-up edge, which results in more consistent surface quality and extended in-service life of the cutting edge. In practical terms, shops can expect fewer tool changes and a more predictable tool-life cycle when machining demanding austenitic or ferritic stainless alloys.

ISO geometry and small corner radius for secure clamping and fine finishes

The insert follows the ISO DCMT11T302 form, with a rhombic shape and a 55° cutting orientation that suits a wide range of turning tasks. The 0.2 mm corner radius supports fine finishing and light profiling, while the 7° relief angle reduces rubbing behind the edge on tight radii. With a plate thickness of 3.97 mm and a central hole featuring a cylindrical bore plus a single-sided countersink (40°–60°), the insert allows secure clamping and repeatable seating in properly matched holders. Compatibility with a given toolholder depends on form, relief, tolerance class, fastening method, size and thickness — selecting the correct combination ensures repeatable results and low vibration levels.

Practical benefits for shop-floor productivity and selection guidance

This grade and geometry are aimed at productive turning workflows: the combination of T6215 coating and the insert’s rigidity supports stable to slightly interrupted cuts, common in both external and internal turning operations. The insert’s one-sided chipbreaker should be chosen to match the workpiece material and the machine setup; the correct chipbreaker and cutting parameters reduce cycle time and improve chip control. As part of an ISO-indexable system — insert, suitable external holder or boring bar, shim and replacement clamp screws — this solution delivers quick indexability, consistent edge angles after indexing and straightforward inventory management for production environments.

FAQ

What advantages does the T6215 coating offer for stainless-steel turning?
The Tungaloy DCMT11T302 T6215 insert uses a CVD-coated grade that enhances wear resistance and reduces built-up edge when machining stainless steels, resulting in improved surface finish and longer edge life.

Is this insert compatible with standard ISO DCMT holders?
Compatibility depends on holder form, relief, tolerance class, fastening method, size and thickness; the DCMT11T302 geometry and central hole are made for secure clamping in holders designed for that ISO specification.

Which operations are most suitable for this insert?
The insert is intended for external and internal turning, particularly under stable to lightly interrupted cutting conditions where the T6215 grade yields reliable performance.

How does the 0.2 mm corner radius influence the result?
A 0.2 mm corner radius supports finer surface finishes and light profiling; it favours finishing passes or where a small nose radius is required to control cutting forces and surface integrity.

What clamping and mounting features should be noted?
The insert has a central cylindrical hole with a one-sided countersink (40°–60°) to permit secure, repeatable clamping together with the correct shim and clamp screw in an ISO-compatible holder.
