DPMT 11T304 T6215 turning insert by Tungaloy

The DPMT 11T304 T6215 is an ISO rhombic turning insert designed for turning applications, optimised for stable to lightly interrupted machining of stainless steel.

• CVD-coated carbide grade T6215 for wear resistance
• ISO rhombic 55° geometry with 11° relief
• 0.4 mm corner radius for fine surface finish
• Single-sided chipbreaker for predictable chip control

Durable carbide grade for demanding stainless steel turning

The insert’s T6215 CVD-coated carbide combines a hard, wear-resistant coating with a tough substrate to cope with the adhesion and built-up edge tendencies of stainless steel. This grade is intended for stable to lightly interrupted turning where consistent flank wear behaviour and predictable tool life are essential. The coating reduces abrasion and prolongs cutting edge performance, which translates into fewer tool changes and improved process uptime. For production environments where repeatability and surface integrity matter, the material choice balances abrasion resistance with fracture toughness to keep costs per part low.

Precise ISO geometry for secure clamping and repeatable results

Engineered as an ISO rhombic insert with a nominal included angle of 55° and an 11° relief, the geometry ensures a secure fit in standard holders and consistent cutting engagement. The insert thickness of 3.97 mm and the central mounting option — a cylindrical hole with a one-sided countersink (40°–60°) — support accurate seating and repeatable positioning. A 0.4 mm corner radius offers a compromise between cutting strength and surface finish, enabling fine external profiles or light finishing passes without sacrificing edge stability. Compatibility with a holder is determined by form, relief angle, tolerance class, clamping method, size and thickness, so correct matching yields stable cutting and better surface results.

Predictable chip control reduces interruptions and rework

Equipped with a single-sided chipbreaker, the insert is configured to promote controlled chip formation when machining ductile and work-hardening stainless alloys. Proper chip control reduces the risk of entanglement, improves evacuation in shallow grooves and minimises heat concentration at the cutting edge. Selecting the appropriate chipbreaker and grade according to workpiece material and machining stability enhances process efficiency, lowers scrap rates and shortens setup times. The result is a more economical turning operation through fewer stoppages and steadier machining windows.

System-ready design and practical application guidance

Delivered as an ISO-standard plate intended for use with a matching external holder or boring bar, the insert forms part of a system that typically includes a support shim, clamping set and replacement screws. The standard dimensions and central mounting facilitate rapid replacement and maintain concentricity in multi-station setups. For specific workpiece materials, cutting parameters and holder compatibility, consult technical documentation or request tailored recommendations; correct pairing of insert, chipbreaker and holder is key to leveraging the grade’s advantages in production. The DPMT11T304 design is optimised for consistent performance in routine turning tasks where reliability and surface quality are required.

FAQ

What materials is this insert suited for?
The DPMT 11T304 T6215 turning insert is formulated primarily for stainless steel machining and performs best under stable to lightly interrupted turning conditions.

Which holder types are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness; the plate’s cylindrical hole with countersink is suitable for many standard external holders and boring bars.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes controlled chip formation for ductile, work-hardening materials, improving evacuation and reducing the risk of chip-related interruptions.

What cutting geometry helps achieve a fine surface finish?
A 0.4 mm corner radius combined with the insert’s 11° relief and 55° rhombic geometry supports fine surface finishes while maintaining edge strength during finishing passes.

Can the grade handle lightly interrupted cuts?
Yes, the T6215 CVD-coated carbide grade is intended for stable to lightly interrupted turning and balances wear resistance with toughness for such applications.
