DCMT 070208 T6215 — Tungaloy turning insert (CVD‑coated cemented carbide, 7° relief)

The DCMT 070208 T6215 is an ISO‑format, rhombic turning insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• *CVD‑coated cemented carbide grade T6215
• *Optimised for stainless steel turning
• *Rhombic 55° geometry, 7° relief angle
• *Single‑sided chipbreaker, central hole with countersink

Consistent cutting performance for stainless steels

The CVD‑coated cemented carbide grade T6215 provides enhanced wear resistance and stable flank behaviour when machining stainless steel. The coating reduces adhesive wear and helps maintain a secure cutting edge under the elevated temperatures typical of austenitic stainless materials. As a result, the insert delivers longer effective life and fewer interruptions for index changes, which supports a more predictable production flow and reduced tooling costs.

Secure clamping and ISO compatibility for straightforward setup

Designed to ISO form 070208, the rhombic insert features a central cylindrical hole with a one‑sided countersink (40°–60°) that ensures positive location in most standard turning holders. The 55° included angle and 7° relief (clearance) angle are matched to widely used ISO holders, making holder selection and replacement straightforward. The recommended system includes the insert, an appropriate external holder or boring bar, shim/underlay and clamp kit, plus replacement screws for reliable fixture integrity.

Productivity and economical machining through optimised geometry

The single‑sided chipbreaker and 0.8 mm nose radius combine to promote controlled chip formation and a robust cutting edge. The moderate nose radius balances surface finish and edge strength: it supports consistent profile accuracy while resisting chipping in interrupted cuts. The insert is particularly suited to stable turning operations where consistent metal removal rates and long tool life are priorities, thereby reducing downtime and improving overall process economy.

Practical guidance for application and selection

This insert is intended for turning applications where the workpiece material and process stability match the grade’s capabilities. Typical uses include external finishing and semi‑finishing of stainless steel components and internal turning where holder rigidity is sufficient. Selection of the chipbreaker and mounting should be based on workpiece stability and the intended depth of cut: choose a more aggressive chip control for heavy continuous cuts, and favour stable clamping and lighter feeds for interrupted conditions. The insert’s ISO conformity simplifies cross‑reference and replacement in existing tool inventories.

FAQ

Is this insert suitable for turning stainless steel?
The DCMT 070208 T6215 insert from Tungaloy is formulated for stainless steel turning under stable to lightly interrupted conditions; the CVD coating and grade T6215 improve wear resistance and edge life in these applications.

Which holders are compatible with this ISO insert?
Compatibility follows ISO form 070208: the rhombic shape, 55° included angle and central hole with countersink ensure fitment with standard ISO turning holders and boring bars that accept DCMT‑format inserts.

What cutting edge geometry should be chosen for finishing work?
For improved surface finish, use a light depth of cut with a smaller feed and maintain the 0.8 mm nose radius; this radius supports a balance between surface quality and edge stability during finishing passes.

How does the chipbreaker affect performance?
The single‑sided chipbreaker is designed to control chips and aid evacuation in turning operations; pairing the chipbreaker style with appropriate cutting data enhances productivity and reduces risk of built‑up edge on stainless steel.

What components form the complete tool system?
A typical system comprises the indexable insert, a matching external holder or boring bar, underlay/shim and clamp set, plus replacement screws to ensure secure and repeatable mounting.
