DCMT070204 T6215 — Tungaloy indexable turning insert for ISO turning, rhombic 07, CVD‑coated carbide

DCMT070204 T6215 is an ISO‑standard indexable insert designed for external and internal turning, optimised for stainless steels under stable to lightly interrupted conditions

• CVD‑coated cemented carbide T6215
• Rhombic 07 insert, 55° cutting geometry
• 0.4 mm corner radius, thickness 2.38 mm
• With cylindrical hole and one‑sided countersink

Stable cutting performance where consistent tool life matters

The CVD‑coated cemented carbide grade T6215 provides a wear‑resistant cutting edge that extends usable tool life during serial turning operations. The combination of coating and substrate reduces flank wear and maintains cutting geometry over longer cycles, which helps to keep cycle times stable and rework rates low. Specified as an ISO‑compliant rhombic insert, the component is intended for machining stainless steels where predictable edge behaviour and low microchipping are priorities.

Precision geometry for secure clamping and reproducible results

With a 55° cutting geometry, 0.4 mm corner radius and 2.38 mm thickness, the insert offers a balance between edge strength and accessibility in medium‑duty turning. The cylindrical hole and one‑sided countersink (40°–60°) ensure consistent positioning in standard ISO toolholders; compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness. Using the correct pocket and clamping set reduces vibration and contributes to repeatable surface finishes.

Effective chip control and productivity in stainless steel turning

The single‑sided chipbreaker design supports controlled chip formation for stable cutting when turning stainless steels, where long, stringy chips can otherwise impede productivity. Choosing the right chipbreaker and grade for the workpiece material and machining stability reduces interruption frequency and minimises tool changes, which in turn yields higher process efficiency and lower overall production cost per part.

System compatibility and workshop implementation

As part of an ISO insert system, this rhombic indexable plate is intended to be used with a matching external holder or boring bar, a suitable shim/clamping set and replacement screws. The insert’s ISO designation and dimensions support straightforward planning for tool inventory and quick changeovers. For applications with marginal stability or interrupted cuts, pairing the insert with a rigid holder and optimised cutting parameters will improve tool life and surface quality.

FAQ

What materials is this insert suited for?
The Tungaloy DCMT070204 T6215 insert is optimised for machining stainless steels and performs best under stable to lightly interrupted cutting conditions.

How does the T6215 grade affect tool life?
The T6215 CVD‑coating enhances wear resistance and helps maintain a sharp edge longer, resulting in more consistent tool life for repetitive turning tasks.

Which holders are compatible with this ISO insert?
Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, size and thickness; use an ISO‑compliant rhombic pocket and matching clamping set for secure fitment.

Is the 0.4 mm corner radius suitable for finishing?
A 0.4 mm radius provides improved edge strength while still allowing good surface finish; for finer finishes, consider smaller radii where holder and stability permit.

Does the insert require a special screw or shim?
Use the standard ISO clamping set and replacement screws specified for the chosen holder; the insert’s cylindrical hole with one‑sided countersink aligns with common ISO fastening interfaces.
