DPMT 070204 T6215 – ISO turning insert by Tungaloy, CVD-coated carbide for stainless steels

The DPMT070204 T6215 is an ISO rhombic turning insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Optimised for stainless steels
• Rhombic ISO insert, 55° geometry
• Cylindrical hole with countersink

Improved tool life through wear-resistant coating

The DPMT070204 T6215 insert features a CVD-coated carbide substrate engineered for enhanced wear resistance when machining stainless steels. The chemical vapour deposition layer increases resistance to built-up edge and abrasion, which translates into a longer tool life and more consistent part quality over longer production runs. For operations that demand repeatable surface finish, the coated grade helps maintain cutting edge integrity, reducing the frequency of index changes and supporting predictable machining cycles.

Secure clamping and geometrical stability for reliable turning

The rhombic shape with a 55° main clearance and an 11° clearance angle offers a balance between access and stability in confined turning zones. The 0.4 mm corner radius and an insert thickness of 2.38 mm contribute to edge strength for light finishing and medium-turning tasks. A cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and repeatable seating in ISO-compatible toolholders; compatibility is determined by insert form, clearance, tolerance class, fastening and size. These geometric features reduce vibration and support steady cutting conditions, which benefits dimensional accuracy and surface quality.

Consistent chip control and practical application guidance

Equipped with a one-sided chipbreaker, this insert promotes reliable chip control during external and internal turning operations. For stainless steels, choosing the appropriate chipbreaker and matching the T6215 grade to the workpiece stability will improve evacuation and reduce recutting of chips. The insert is intended for use in both continuous and lightly interrupted cuts; selecting a suitably rigid holder and optimising feeds and speeds for the alloy and machining setup will preserve edge life and deliver stable process results. Clear chip management reduces downtime and supports safer, more efficient production.

FAQ

What materials is this insert suitable for?
The DPMT070204 T6215 insert from Tungaloy is optimised for machining stainless steels under stable to lightly interrupted conditions, leveraging its CVD-coated carbide grade for improved wear resistance.

Which toolholders are compatible with this insert?
Compatibility depends on the ISO rhombic form, 55° geometry and the insert thickness; use ISO-compatible turning holders sized for DPMT070204 and ensure the holder accepts a cylindrical hole with countersink for secure clamping.

What is the corner radius and what does it mean for machining?
The corner radius is 0.4 mm, which offers a compromise between edge strength and the ability to achieve finer surface finishes; it is suitable for finishing and medium-turning in stainless steels.

Is the insert coated and how does the coating help?
Yes — the insert is CVD-coated carbide (grade T6215); the coating enhances resistance to abrasion and built-up edge, improving tool life and process stability when machining challenging alloys.

Why is the hole style important for this insert?
The cylindrical hole with a one-sided countersink (40°–60°) provides reproducible seating and stronger clamping in the toolholder, which reduces movement under cutting forces and supports consistent dimensional results.
