DCMT 11T304 T6215 turning insert (Tungaloy) — CVD-coated carbide, 55°

A DCMT11T304 indexable insert designed for external and internal turning, optimised for turning rostfreier Stahl under stable to lightly interrupted cutting conditions.

• CVD-coated carbide T6215 for wear resistance
• Rhombic shape with 55° cutting angle
• 0.4 mm corner radius for fine profiles
• Single-sided chipbreaker, with hole + countersink

Productivity gains from a wear-resistant grade

The T6215 grade is a CVD-coated carbide developed to combine wear resistance with steady cutting performance. In continuous and lightly interrupted operations the coating reduces flank wear and enhances tool life, which directly lowers tool-change frequency and improves overall machine uptime. For production-focused environments this grade balances edge stability with the ability to maintain a consistent surface finish on rostfreier Stahl, making it a sound choice where predictable results are required.

Geometry tailored for chip control and access

A rhombic geometry with a 55° cutting angle provides good access to profiles and grooves while maintaining favourable cutting forces. The 0.4 mm corner radius helps to produce fine radii and reduces edge chipping when moderate feeds are used. The single-sided chipbreaker assists with controlled chip formation in turning tasks, and the insert’s central hole with a cylindrical bore and a one-sided countersink (40°–60°) ensures secure clamping and repeatable positioning in compatible holders.

Clear compatibility and application guidance

Belonging to the ISO turning indexable insert family, this item is compatible with holders that match the insert form, free angle, tolerance class, fixing method, size and thickness. Selection of the correct chipbreaker and grade should be aligned with workpiece stability and cutting parameters; matching a rigid holder and correct clamping parts ensures the DCMT11T304 T6215 insert performs as intended. The system typically comprises the insert, a suitable external holder or boring bar, a shim or clamp set and replacement screws.

Economical machining with consistent surface quality

Choosing a coated hardmetal insert that offers stable chip formation and broad material suitability leads to lower rework rates and more consistent components from batch to batch. The combination of a wear-resistant coating and robust edge geometry supports longer tool life and repeatable dimensions, which is advantageous for subcontractors and production shops aiming for reliable cycle times and predictable costs per part. The manufacturer’s focus on productive machining underpins this insert’s role in efficient turning operations.

FAQ

What materials is this insert suited for?
The Tungaloy DCMT11T304 T6215 insert is specified for machining rostfreier Stahl under stable to lightly interrupted conditions; the T6215 grade offers wear resistance suitable for that material family.

How does the 55° geometry influence machining?
A 55° rhombic geometry provides improved access to profiles and reduces radial cutting forces, which helps maintain dimensional stability during turning with this insert.

What does the central hole and countersink provide?
The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and repeatable seating in appropriately designed holders for indexable inserts.

Which components are required for a complete system?
A complete setup generally includes the indexable insert, a compatible external holder or boring bar, a shim or clamp set and replacement screws to secure the insert in the holder.
