CNMM 190612 T9225 Turning insert — Tungaloy, CVD-coated carbide, 80° rhombic

The CNMM190612 T9225 is an ISO rhombic indexable insert designed for robust external and internal turning applications where interrupted cuts or variable engagement demand increased toughness.

• CVD-coated carbide T9225
• 80° rhombic geometry
• 1.2 mm corner radius
• Single-sided chipbreaker with hole

Reliable cutting performance for medium-to-heavy turning

The rhombic 80° geometry combined with the T9225 CVD-coated carbide grade delivers a stable cutting edge that tolerates varying engagement conditions. This combination is engineered for medium-to-heavy steel machining, providing a balance between edge robustness and wear resistance. The grade’s enhanced toughness reduces the risk of edge chipping during intermittent cuts, while the coating improves thermal stability and sliding behaviour at higher cutting speeds. Practical benefits include fewer unplanned tool changes and more consistent component quality.

Secure seating and predictable clamping in ISO toolholders

Designed as an ISO-conformant plate, the insert features a cylindrical locating hole and standard dimensions that ensure repeatable seating in compatible holders. The 6.35 mm thickness and the rhombic outline contribute to secure clamping and minimal micro-movement under load. As a result, setup times are reduced and repeatability between indexed positions is improved. For shops relying on predictable clamping behaviour, this leads to fewer rejects and a more stable production rhythm.

Optimised chip control and extended tool life

The single-sided chipbreaker profile is matched to typical steel-cutting conditions and supports reliable chip formation and evacuation. By guiding chips away from the cutting zone, the insert helps maintain surface finish and reduces heat concentration at the cutting edge. The 1.2 mm corner radius offers a compromise between strength and finish capability: it increases edge life while still permitting satisfactory surface quality on turned parts, particularly where robustness under variable engagement is required.

Application advice and handling recommendations

This indexable plate is best employed for external and internal turning on steels where changes in cut depth or interrupted sections are common. Use holders compatible with ISO rhombic inserts and ensure the clamping torque and seat cleanliness meet the toolholder manufacturer’s guidance. For optimal results, pair the insert with appropriate feeds and speeds that reflect the T9225 grade’s focus on toughness rather than extreme finishing parameters. If uncertain about parameter selection, a brief process trial with incremental adjustments will quickly establish the best balance between productivity and tool life.

FAQ

What materials is this insert suitable for?
The CNMM190612 T9225 indexable insert from Tungaloy is formulated primarily for steel machining and performs well in medium-to-heavy steel turning operations.

Will the insert fit existing ISO rhombic holders?
Yes — the plate follows ISO dimensions and the cylindrical locating hole ensures compatibility with standard ISO rhombic toolholders when form, size and thickness match the holder specifications.

How does the T9225 grade affect tool life?
The T9225 CVD-coated carbide grade emphasises toughness and thermal stability, offering improved resistance to chipping in interrupted cuts and consistent wear behaviour under variable engagement.

What is the benefit of the 1.2 mm corner radius?
A 1.2 mm corner radius increases edge strength and contributes to longer tool life in heavier cuts while maintaining acceptable surface finish for most turned components.

Is this insert suitable for finishing passes?
While the insert is optimised for robust performance, it can be used for semi-finish and certain finishing passes; however, for ultra-fine finishing a smaller corner radius or a grade optimised for low cutting forces may be preferable.
