DCMT070204 T6215 — DCMT 070204 turning insert, CVD-coated carbide (Tungaloy)

DCMT070204 T6215 is an ISO rhombic turning insert for precision external and internal turning, optimised for stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide for high wear resistance
• 55° rhombic geometry for versatile turning
• 0.4 mm corner radius for fine surface finish
• Cylindrical hole with countersink for secure clamping

Long lasting, wear‑resistant cutting for stainless steels

The CVD‑coated carbide grade T6215 provides a robust cutting edge and predictable wear behaviour when machining stainless steels. The chemical vapour deposition layer improves resistance to adhesion and work‑hardening typical of these alloys, which helps to extend tool life and reduce unexpected downtime. Selecting a CVD‑coated grade means fewer insert changes and more consistent batch quality, which supports efficient production planning and lowers the cost per turned component.

Geometry engineered for accuracy and accessibility

The 55° rhombic geometry combined with a 0.4 mm corner radius and a 7° relief angle delivers a balance of accessibility and rigidity: the acute included angle allows approach into shoulders and internal profiles, while the modest corner radius improves surface finish without compromising strength. The 2.38 mm plate thickness ensures adequate support in standard ISO holders, translating into stable cutting conditions and repeatable dimensional results for both external and internal turning tasks.

Secure fastening and simple holder compatibility

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening method, size and thickness; the DCMT070204 is supplied with a cylindrical hole plus a single‑sided countersink (40°–60°) to match common clamping systems. This hole design provides reliable seating and repeatable register position on compatible inserts, reducing setup time and improving process security. Where uncertainty exists on holder fitment, the insert designation and tolerance class should be checked against the holder specification to ensure optimal clamping and cutting performance.

Predictable chips and steady productivity

The one‑sided chipbreaker is matched to the grade and intended cutting mode, promoting controlled chip formation under stable to slightly interrupted conditions. Predictable chip control helps maintain machine uptime and operator safety while supporting consistent surface quality — an advantage in repetitive production environments. With the combination of Tungaloy metallurgy and ISO standardisation, the insert supports efficient batch processing and dependable finishing, enhancing both throughput and product conformity.

FAQ

What materials is this insert suited for?
The DCMT070204 T6215 insert is specified for turning stainless steels, with the CVD coating improving resistance to adhesion and enabling longer tool life in these alloys.

How does the insert attach to a holder?
The plate features a cylindrical hole with a single‑sided countersink (40°–60°) for secure clamping; compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness.

What benefits does the T6215 grade provide?
The T6215 CVD‑coated carbide grade offers enhanced wear resistance and stable cutting behaviour, which results in fewer index changes and more consistent surface finishes during turning.

Which geometrical features affect accessibility and finish?
The 55° rhombic geometry, combined with a 0.4 mm corner radius and 7° relief, allows access to shoulders and internal profiles while delivering improved surface quality on finished parts.

Can this insert be used for internal turning as well as external?
Yes — the insert’s rhombic shape and compact geometry make it suitable for both external and internal turning operations when used with compatible ISO holders.
