DNMG150612 T5105 Tungaloy — ISO indexable turning insert for high-speed cast iron turning

The DNMG150612 T5105 is an ISO-standard indexable turning insert engineered for high-speed external and internal turning of cast iron under stable machining conditions.

• CVD-coated carbide T5105
• Optimised for cast iron machining
• 55° rhombic geometry with cylindrical hole
• Double-sided chipbreaker for stable cuts

Consistent high-speed performance for cast iron work

The core advantage of this insert lies in its CVD-coated carbide composition and the T5105 grade, which together provide wear resistance and thermal stability during high cutting speeds. The combination of coating and substrate reduces flank wear and extends edge life, which translates into fewer indexings and longer tool cycles in series production. For operations where cycle time and repeatable surface quality matter, the indexable insert design permits quick replacement and reliable geometry retention, supporting uninterrupted production runs and predictable tool-change planning.

Geometry and chip control that reduce cycle time

The 55° rhombic geometry with a double-sided chipbreaker supports controlled chip formation and evacuation when turning cast iron. The rhombic shape offers access to both external and internal features, while the chipbreaker design reduces vibration and improves surface finish under steady, clamped conditions. The insert’s cylindrical hole and standardised ISO form ensure secure clamping in matching toolholders; combined with the correct pad and clamp set, the system provides consistent seat repeatability and minimal runout for precision turning.

System compatibility and secure mounting for repeatable results

Compatibility with holders is determined by form, relief angle, tolerance class, fastening, size and thickness; the insert’s 6.35 mm thickness and 15 mm size comply with common ISO clamping systems. The recommended system build comprises the ISO indexable insert, a matching external holder or boring bar, a support pad/clamp set and replacement screws to guarantee correct torque and seating. This structured approach ensures reliable force transmission, repeatable positioning and reduced risk of loosening during heavy cuts, which is critical for keeping rejects and machine downtime to a minimum.

Durability, economical cutting and predictable outcomes

With the T5105 carbide grade and CVD coating, the insert is designed to offer good wear resistance and stable edge life when operated within its intended envelope. The geometry and grade selection help to achieve consistent surface quality and reduced tool consumption in long production runs. For machining strategies that prioritise throughput and reproducibility, this insert provides an effective balance of cost-efficiency and process stability.
