CNMG 120408 T9215 CNMG120408 — Tungaloy indexable turning insert for Turning

CNMG120408 T9215 Tungaloy insert for ISO-standard turning applications, designed for medium steel machining with secure clamping and repeatable edge performance

• ISO rhombic insert CNMG120408
• CVD-coated carbide grade T9215
• Double-sided chipbreaker, cylindrical hole
• 0° clearance angle, 0.8 mm corner radius

Engineered for steady, high-productivity turning

The rhombic insert is built to deliver reliable cutting performance in industrial turning. The CVD-coated carbide construction and T9215 grade combine wear resistance with toughness, enabling productive machining of medium steel under continuous to lightly interrupted cuts. The geometry—an 80° included angle with 0° clearance—supports stable engagement and predictable chip flow, which reduces the need for frequent tool changes and helps maintain cycle-time targets. Compatibility with standard ISO holders ensures straightforward integration into existing tool systems without costly rework.

Secure clamping and repeatable edge life

A cylindrical hole and double-sided configuration provide mechanical stability and two usable cutting edges per index, contributing to lower tooling costs per part. The insert’s rhombic form and precise tolerance control aid repeatable seating in matched holders, ensuring consistent orientation and cutting angle across index changes. As a result, the component offers dependable dimensional control and surface finish when combined with a properly specified holder and clamping set. This design focus supports throughput and reduces downtime spent on re-clamping or adjustment.

Material and coating explained for practical selection

The substrate of the insert is carbide and the surface is CVD-coated, a combination chosen for general-purpose steel machining where a balance of wear resistance and fracture toughness is required. The T9215 grade is specified as a first choice for medium steel, providing stable chip formation and good edge life under typical shop-floor conditions. For operators unfamiliar with coatings, CVD provides a uniform, wear-resistant layer that enhances life at elevated temperatures and under abrasive contact, while the core carbide preserves edge strength.

Practical guidance for application and holder compatibility

Use the insert for external and internal turning where the material and cutting conditions match the T9215 intent: medium carbon and alloy steels under continuous or slightly interrupted cuts. The insert fits ISO systems; compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness. Consider the 0.8 mm corner radius for balancing edge strength and achievable surface finish, and the 4.76 mm plate thickness when selecting a matching seat and screw. Adopting the correct chipbreaker and stability criteria will maximise tool life and process reliability.
