DNMG150412 T9215 indexable insert — 55° rhombic, CVD-coated carbide for turning — Tungaloy

DNMG150412 T9215 is a 55° rhombic, ISO-standard indexable insert designed for external and internal turning in medium-steel applications

• CVD-coated carbide T9215 for medium steel
• 55° rhombic geometry for versatile turning
• 1.2 mm corner radius for robust edge
• Double-sided chipbreaker with cylindrical hole

High-productivity turning for medium steels

The CVD-coated grade T9215 combines high wear resistance with fracture resistance, making it a first choice for productive machining of medium steels. Its cutting behaviour is optimised for continuous to slightly interrupted cuts, so sustained production runs benefit from stable tool life and predictable replacement intervals. The coating reduces flank wear under elevated cutting speeds, which contributes directly to consistent component tolerances and a lower rate of tooling changeovers.

Robust edge geometry that supports stability

A 55° rhombic geometry paired with a 1.2 mm corner radius provides a favourable balance between cutting strength and access to part features. The geometry is engineered to withstand radial loads and occasional interruptions, while the rounded corner reduces notch formation and chipping. The insert is double-sided, offering two indexable edges per side, and is drilled with a cylindrical central hole to secure it reliably in standard ISO-compatible holders and clamping systems.

Clear guidance on compatibility and mounting

This insert belongs to the ISO-standard indexable turning family and is compatible with matching external holders or boring bars when form, clearance angle, tolerance class, fastening, size and thickness correspond. The clearance angle is 0°, and the plate thickness is 4.76 mm, so the insert is to be mounted with the appropriate shim/clamp set and replacement screws for safe, repeatable seating. Correct matching of holder and insert minimises vibration and supports repeatable surface finish and dimensional results.

Optimised chip control and targeted application range

The integrated double-sided chipbreaker is designed to manage chip formation when machining medium steel, improving evacuation and reducing the risk of built-up edge. Selection of the chipbreaker style and the T9215 grade should be aligned with workpiece stability and feed rate; the system performs best under steady feeds where the chip form remains consistent. Typical applications include both external and internal turning, where productivity and tool life are prioritised.
