DCMT 11T312 T9215 Tungaloy indexable turning insert — ISO rhombic 55° for turning

A DCMT11T312 T9215 indexable turning insert designed for ISO-standard external and internal turning, optimised for medium-steel machining and secure clamping in compatible holders

• ISO rhombic insert, 55° cutting geometry
• CVD-coated carbide grade T9215
• Suitable for medium steel turning
• Cylindrical hole with 40°–60° countersink

Increased productivity through high wear resistance

The CVD-coated carbide grade T9215 combines wear resistance with fracture safety to support productive machining under continuous to slightly interrupted conditions. The coating enhances edge life by reducing abrasive wear, while the substrate maintains toughness, resulting in longer tool life and fewer indexings. With a 1.2 mm corner radius the insert balances strength and surface finish, making it suitable for programmes where stability and consistent cycle times are required.

Reliable clamping and repeatable setup

Designed as an ISO-standard rhombic insert, the geometry and tolerance class ensure predictable fitment in compatible holders. The cylindrical hole with a 40°–60° countersink provides a secure mechanical interface that reduces micro-movement during cutting and simplifies indexing. A controlled fit—determined by form, relief angle and thickness—translates into faster set-ups and repeatable results across batches, which is especially valuable in production environments seeking reduced downtime.

Practical guidance for application and tooling systems

Optimised for medium steel turning, the insert performs well in both external and internal turning operations when paired with an appropriate holder or boring bar, a matching shim or clamp set and correct fastening screws. The single-sided chipbreaker supports predictable chip formation; selecting the matching chipbreaker and grade according to workpiece stability and cutting conditions improves surface quality and process reliability. The system approach—insert, holder, mount and spare screws—enables straightforward replacement and minimises inventory complexity.
