CNMM 190612 T9215 — ISO rhombic turning insert for turning by Tungaloy

A CNMM190612 T9215 indexable insert designed for ISO‑standard external and internal turning, combining a CVD‑coated carbide grade for high wear resistance and reliable performance in continuous to light interrupted cuts.

• CVD‑coated carbide T9215 for medium steel
• ISO CNMM190612 rhombic geometry
• 1.2 mm corner radius for robust edge
• 6.35 mm thickness for increased stability

Consistent performance for medium‑steel production

The CVD‑coated carbide grade T9215 delivers high wear resistance coupled with strengthened fracture toughness, making the insert particularly suitable for the demands of medium‑steel turning. The coating reduces flank wear and prolongs effective cutting life, which supports higher productivity in continuous or lightly interrupted cutting conditions. For production planners, this translates into fewer insert changes, more consistent cycle times and better machine uptime.

Geometry and edge design that improve process reliability

Manufactured to the ISO CNMM190612 form, the rhombic shape and 80° principal angle provide a balance between strength and access to the cutting zone. The 1.2 mm corner radius offers a robust cutting edge that tolerates increased feed rates, while the single‑sided chipbreaker assists reliable chip formation when machining typical steels. The insert’s cylindrical hole and the specified 6.35 mm thickness contribute to secure clamping and reduced vibration, helping to maintain surface integrity and dimensional repeatability.

straightforward integration into ISO tool systems

The insert is part of a standard ISO turning system: indexable insert, matching external holder or boring bar, shim/clamp set and replacement screws. Compatibility with a chosen holder depends on form, clearance angle (0°), tolerance class, fastening type, size and thickness; attention to these dimensions ensures correct seating and clamping. The standardised CNMM form simplifies procurement and interchangeability across tool programmes, reducing inventory complexity for toolrooms.

Practical advantages for toolroom and production use

Choosing this grade and geometry supports a pragmatic combination of tool life and process security. The CVD coating reduces adhesive and abrasive wear mechanisms, while the carbide substrate provides the core toughness to resist chipping. For manufacturers seeking reproducible results and a cost‑effective process, this insert enables productive material removal with controlled chip behaviour and predictable regrinding or replacement intervals.

FAQ

Which materials is this insert best suited for?
The CNMM190612 T9215 insert is tailored for medium steel machining; the Tungaloy T9215 grade combines wear resistance and fracture toughness suitable for continuous and lightly interrupted turning operations.

How does the insert secure in the holder and what must be matched?
Correct seating requires a matching holder for the CNMM form; compatibility depends on the insert form, clearance angle (0°), tolerance class, fastening type, size (19 mm) and thickness (6.35 mm).

What chip control can be expected with this geometry?
The single‑sided chipbreaker of this rhombic insert promotes controlled chip formation for standard turning feeds, supporting safer evacuation and consistent surface finish during medium‑steel cutting.

What key dimensions define the insert’s strength and access?
The combination of an 80° principal angle, 1.2 mm corner radius and 6.35 mm thickness provides a robust edge with good access to the workpiece, balancing strength and cutting reach.
