CNMM 250932 T9215 indexable insert for turning — Tungaloy

CNMM250932-TUS is an ISO-standard rhombic indexable insert intended for external and internal turning, engineered for productive machining of medium steel.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• 3.2 mm corner radius for robust profiling
• ISO rhombic shape with 80° included angle

High productivity through wear-resistant grade and proven coating

The insert uses a CVD-coated carbide substrate in grade T9215, which combines elevated wear resistance with good fracture tolerance. This composition makes the tool a reliable choice for continuous to slightly interrupted cuts in medium steel, enabling longer edge life and fewer tool changes. The coating process forms a protective hard layer that reduces flank wear; for production environments this translates directly into steadier cycle times and more predictable tool consumption.

Secure mounting and ISO compatibility for straightforward tool assembly

Designed as an ISO-standard turning insert, compatibility with holders is achieved through matching form, relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole for positive locating and safe clamping in suitable chucks or boring bars. The specified 9.52 mm thickness and 25 mm size are standard dimensions that simplify tool planning and replacement in established tool systems, reducing downtime during insert exchanges.

Geometry and chip control that support consistent surface quality

The rhombic shape with an 80° included angle and a 3.2 mm corner radius provides a robust cutting edge for profiling and shoulder work, improving resistance to mechanical shock. The integrated TUS chipbreaker is matched to the grade and typical steel applications to support controlled chip flow and surface finish. Selecting this insert helps maintain repeatable machining results with a focus on stable cutting conditions rather than overly aggressive feeds, which is especially valuable for jobs where consistent quality is required.

FAQ

What materials is this insert best suited for?
The CNMM250932-TUS insert in Tungaloy’s T9215 grade is optimised for medium steel and offers a balance of wear resistance and fracture toughness for productive machining.

Is the insert compatible with standard ISO holders?
Yes—being an ISO-standard rhombic insert, compatibility depends on matching form, relief angle, tolerance class, fastening, size and thickness; the CNMM250932-TUS is designed for such systems.

What role does the TUS chipbreaker play?
The TUS chipbreaker promotes predictable chip formation and evacuation, supporting surface quality and reducing the risk of chip-related interruptions during turning operations.

Can this insert be used for interrupted cuts?
The T9215 grade and the insert geometry are suitable for continuous to slightly interrupted cuts; heavier interruptions may require a different grade or insert geometry.

How is the insert secured in the holder?
The insert has a cylindrical hole for positive locating and is fixed using the appropriate clamping/shim set and screws as per the ISO holder system.
