CNMM 250924 T9215 ISO turning insert — CVD-coated carbide for turning, Tungaloy

The CNMM 250924 T9215 is a rhombic ISO turning insert designed for medium-steel machining, offering a CVD-coated carbide substrate and a single-sided chipbreaker for reliable chip control in continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215 for wear resistance
• Rhombic CNMM shape with 80° cutting angle
• 2.4 mm corner radius for robust edge strength
• Optimised for medium steel and light interrupted cuts

Longer tool life through advanced CVD coating and grade selection

The CVD-coated T9215 grade combines a wear-resistant surface layer with a tough carbide substrate to balance abrasion resistance and fracture safety. This configuration is particularly effective in continuous production where long tool life reduces changeover frequency and machine downtime. The coating process creates a thin, uniform layer that protects the substrate against adhesive and abrasive wear; as a result, cutting edge life is extended and the number of regrinds or insert changes is reduced, improving overall machining economy.

Predictable geometry for steady process results

Manufactured to ISO dimensions in a rhombic CNMM form, the insert features an 80° cutting angle and a 0° relief angle that fit standard external and internal turning holders. The 2.4 mm corner radius provides a compromise between edge strength and finish capability, while the 9.52 mm thickness boosts stability under load. Compatibility to a given holder is defined by form, relief angle, tolerance class, fastening method, size and thickness, so the insert integrates into existing tool systems with repeatable clamping and concentricity when matched correctly.

Better chip control and process security for productive turning

The single-sided chipbreaker is optimised for medium-steel applications and supports consistent chip formation in both continuous and lightly interrupted cuts. Stable chip flow reduces the risk of built-up edge and vibration, which in turn improves surface finish and reduces scrap. The carbide substrate ensures breakage resistance under typical turning forces, enabling higher cutting parameters and consequently improved productivity without compromising part integrity.

Seamless system integration and straightforward handling

The insert is supplied in the ISO CNMM format with a cylindrical locating hole for positive seating in compatible holders; a matching shim or clamping set and replacement screws form the complete system. As an ISO-standardised component, the insert simplifies stock management and replacement planning across multi-shift operations. Labelling and manufacturer SKU make reordering predictable and ensure identical performance across batches, supporting process stability and ease of procurement.

FAQ

What materials is this insert designed for?
The CNMM250924 T9215 insert is formulated for medium steel machining; its CVD-coated T9215 grade balances wear resistance and fracture safety for continuous to light interrupted cuts.

Which holder characteristics determine compatibility?
Compatibility is determined by insert form, relief angle, tolerance class, fastening type, size and thickness; the CNMM format and cylindrical hole require a matching ISO CNMM holder and clamping set.

How does the chipbreaker affect performance?
The single-sided chipbreaker stabilises chip formation and evacuation in medium-steel turning, improving surface finish and reducing the likelihood of built-up edge or vibration-related defects.

Is this insert suitable for interrupted cuts?
Yes — the carbide substrate and T9215 coating provide breakage resistance suitable for continuous machining and light interrupted cuts; heavy interruptions may require a different geometry or grade.

Which dimensions should be considered when reordering?
Key dimensions for reordering are the ISO designation (CNMM250924), corner radius 2.4 mm, thickness 9.52 mm, and the manufacturer article number 6774093 to ensure identical replacement parts.
