DNMG 150412 T5125 indexable insert for turning — Tungaloy

The DNMG 150412 T5125 is an ISO‑standard rhombic turning insert designed for external and internal turning, optimised for interrupted cuts and less stable machining conditions.

• CVD-coated carbide grade T5125
• 55° rhombic geometry for versatile turning
• Double-sided chipbreaker for interrupted cuts
• Cylindrical-hole design for secure clamping

Consistent performance under interrupted cutting conditions

The combination of a CVD coating with a tough carbide substrate delivers improved resistance to chipping and crater wear, making this insert a reliable choice when machining cast iron under interrupted cutting. The T5125 grade is formulated to promote stable chip formation, which reduces vibration and tool damage in applications where cut conditions fluctuate. For production environments this means fewer tool changes, more predictable cycle times and improved component quality, translating into measurable gains in efficiency.

Clear compatibility and secure fixture for trouble-free use

The rhombic 55° geometry and the cylindrical locating hole ensure secure seating and repeatable clamping in ISO holders that match form, relief angle, tolerance class, fastening and thickness. The 1.2 mm corner radius balances edge strength and dimensional control, providing robustness for roughing while still allowing acceptable profile definition. Compatibility is determined by the insert form and the holder specification; verifying those parameters before assembly ensures correct fitment and safe operation.

Longer tool life with optimised chip control

A double-sided chipbreaker combined with the T5125 coating helps control chips during unstable conditions, reducing thermal and mechanical shock at the cutting edge. The insert’s 4.76 mm thickness and rhombic form contribute to mechanical stability, while the grade composition supports effective wear resistance on abrasive cast iron varieties. These characteristics improve process security and help maintain surface finish across production runs, lowering scrap rates and boosting overall throughput.

Practical application guidance and technical clarity

This indexable insert is intended for turning operations and is suited to both external and internal work when used with a compatible external holder or boring bar. The ISO classification and standardised geometry simplify tool selection for workshop planners and operators: match the insert’s 55° form and dimensions to the holder specification, choose a suitable clamping screw and backing plate, and select cutting parameters that reflect the workpiece material and machine rigidity. If specifications require clarification—such as optimal feeds, speeds or coolant strategy—technical consultation is available to adapt the insert to the specific machining scenario.

FAQ

What materials is this insert best suited for?
The Tungaloy DNMG 150412 T5125 insert is optimised for cast iron applications and performs well in interrupted cuts thanks to the T5125 CVD-coated carbide grade.

Is the DNMG 150412 compatible with standard ISO holders?
Yes, the insert follows ISO geometry; compatibility depends on matching holder form, relief angle, tolerance class, fastening method, size and thickness to the insert specification.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker on the DNMG 150412 improves chip control in variable cutting conditions, reducing edge stress and helping to extend tool life while maintaining surface quality.

Can the insert be used for internal turning or boring operations?
The geometry and clamping arrangement suit both external turning and internal operations when paired with a suitable boring bar or holder that accepts DNMG‑type inserts.

Which product identifiers should be quoted when ordering?
Please reference the Tungaloy DNMG 150412 T5125 indexable insert and the manufacturer article number 6850207 (SKU 6850207-Tungaloy) when placing orders or requesting technical information.
