DNMG 150412 T5115 — Turning insert by Tungaloy (CVD-coated carbide, rhombic 55°)

DNMG150412 T5115 Tungaloy turning insert for ISO-compatible external and internal turning applications, designed as a universal grade for cast iron with a balanced mix of wear resistance and edge stability

• CVD-coated carbide grade T5115
• Double-sided chipbreaker for repeatable cuts
• Rhombic DNMG geometry with 55° lead angle
• Cylindrical hole for secure clamping
• 1.2 mm corner radius for robust edges

Consistent cutting performance for cast-iron turning

The CVD-coated carbides used in this grade deliver a practical balance between wear resistance and edge stability, which is essential for medium-duty turning of cast iron. The coating increases resistance to abrasion and built-up edge formation, while the substrate guarantees toughness. For production environments seeking steady tool life and repeatable part quality, this combination reduces process variance and supports predictable machining cycles, lowering scrap rates and improving throughput.

Geometry and stability that improve surface finish and tool life

The DNMG rhombic shape with a 55° approach gives a compromise between strength and accessibility for external and internal operations. The 1.2 mm corner radius provides additional edge reinforcement, reducing the risk of chipping at interrupted cuts and improving surface finish on standard turning passes. The double-sided chipbreaker enables two usable edges per indexation, which extends service intervals and simplifies inventory management for common turning tasks.

Compatibility, clamping and practical handling in the toolroom

ISO standardisation of the insert series ensures broad compatibility with matched external holders and boring bars; clamping fit depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert’s cylindrical hole supports secure mechanical clamping and repeatable seating, which is particularly important when switching between holders or when high positional accuracy is required. Stocking ISO-compliant inserts simplifies tool change procedures and minimises downtime.

Application guidance and process reliability

Designed as a universal grade for cast iron, the T5115 selection is aimed at workshops and small series production where consistent tool life and reliable surface integrity matter. Correct selection of chipbreaker and grade according to material, machining method and machine rigidity will yield the best results. For customers seeking to scale operations, the combination of the CVD-coated grade and ISO geometry offers an economical route to stable production, while reducing the frequency of operator intervention and rework.

FAQ

What materials is this insert best suited for?
The Tungaloy DNMG150412 T5115 turning insert (SKU 6850209-Tungaloy) is designed as a universal grade for cast iron and performs well where a balance of wear resistance and edge stability is required.

How does the T5115 coating improve performance?
The CVD coating on the T5115 grade increases abrasion resistance and reduces built-up edge formation, extending the effective tool life of the insert during typical turning operations.

Is the insert compatible with standard ISO holders?
Yes, the insert belongs to an ISO indexable insert series; compatibility with a given holder depends on form, relief angle, tolerance class, fastening and size, so ensure the holder matches the DNMG150412 geometry.

Can the insert be used for internal turning or boring?
The rhombic DNMG geometry and 55° approach make the insert suitable for many external and internal turning tasks when paired with an appropriate boring bar or holder.

How many cutting edges are available per insert?
The insert is double-sided with a chipbreaker on each side, providing multiple indexations to extend service life and reduce replacement frequency.
