DNMG150412 T515 — DNMG 150412 indexable insert for turning by Tungaloy, CVD‑coated carbide

The DNMG150412 T515 is an ISO‑standard indexable insert designed for economical external and internal turning, optimised for the machining of cast iron.

• CVD‑coated carbide grade T515
• Suitable for cast iron machining
• Rhombic DNMG shape, 55° cutting angle
• Double‑sided chipbreaker, with cylindrical hole

Productive cast iron turning with consistent chip control

The combination of a CVD‑coated cutting surface and a double‑sided chipbreaker delivers reliable chip formation during continuous and interrupted cuts. The CVD layer improves wear resistance at raised cutting speeds, while the chipbreaker geometry helps evacuate chips and reduces heat concentration. For workshops focused on throughput, this translates into longer tool life and fewer insert changes, supporting more predictable cycle times and lower per‑component cost.

Precise geometry for secure clamping and predictable results

A rhombic DNMG profile with a 55° cutting angle and a 0° clearance angle ensures universal applicability in standard external and internal turning holders. The cylindrical hole and defined tolerance classes permit secure fastening with the appropriate clamp set and shim plate, so the insert seats without play. Consistent seating reduces vibration and improves surface finish, making the insert suitable for both roughing and finishing passes when paired with a matching holder and correct machine rigidity.

Robust composition and grade selection for application stability

Manufactured from carbide and specified in the T515 grade, the insert is tailored for economical cast iron machining. The 1.2 mm corner radius balances edge strength and surface quality, resisting chipping in interrupted cuts. Where higher stability or different workpiece materials are required, the choice of chipbreaker style and grade can be adapted; the insert’s reversible design allows two cutting edges per side, enhancing value per insert.

Integration into the machining system for hands‑on productivity

The insert forms part of a system: ISO indexable insert, a compatible external holder or boring bar, a seating shim or clamp set, and replacement clamping screws. Compatibility depends on shape, clearance angle, tolerance class, fixing method, size and thickness; matching these parameters prevents misfit and suboptimal cutting conditions. Selecting the correct holder and clamping components preserves the insert’s performance and helps achieve repeatable results across batches.

FAQ

What materials is this insert best suited for?
The DNMG150412 T515 insert is designed primarily for machining cast iron; the T515 grade and CVD‑coated carbide base provide wear resistance and stable chip formation for that material class.

Is the insert reversible and how many cutting edges are available?
This rhombic insert features a double‑sided chipbreaker and is reversible, offering multiple indexed cutting edges depending on orientation and wear.

How does the 55° geometry affect cutting performance?
A 55° cutting angle balances cutting forces and access to the workpiece; it is versatile for external and internal turning and contributes to predictable cutting behaviour in standard holders.

Which components are required to mount the insert correctly?
Proper installation requires a compatible DNMG‑style external holder or boring bar, a seating shim/washer or clamp set, and the correct clamping screws; compatibility depends on shape, thickness (4.76 mm) and tolerance class.

What does the T515 grade indicate?
T515 denotes a carbide grade optimised for economical cast iron machining, combining toughness and wear resistance under typical turning conditions.
