CNMM 190608 T9215 Turning Insert – Tungaloy, CVD-coated carbide, 80° rhombic

The CNMM190608-TUS T9215 is an ISO-standard indexable turning insert intended for medium-steel machining, optimised for continuous to light interrupted cuts and compatible with standard 80° rhombic holders.

• CNMM 190608 form, 80° rhombic geometry
• CVD-coated carbide grade T9215 for steels
• Cylindrical hole for secure clamping
• 0.8 mm corner radius for precise profiles

Precise fit and predictable clamping for reliable setups

The insert follows the ISO CNMM190608 specification so holder compatibility is defined by form, clearance angle, tolerance class, size and thickness; this ensures repeatable seating and clamping in a matched toolholder. When the clamping system and underlay/shim are selected to match the cylindrical hole, setup time is reduced and tool life becomes more predictable. The standardised geometry supports quick tool changes and unchanged cutting kinematics across batches, which is particularly valuable in series production where process stability is paramount.

Coating and grade engineered for productive steel turning

The cutting material is a CVD-coated carbide in grade T9215, designed as a first choice for medium-steel applications by combining wear resistance with good fracture toughness. This coating system extends life in continuous operations and resists flank and crater wear under stable cutting conditions. For shops aiming to increase throughput, the grade enables higher cutting volumes before index changes, while still maintaining dimensional accuracy on turned components. The balanced properties make it suitable where a mix of surface finish and economy is required.

Geometry and chip control for surface quality and process safety

The 80° rhombic geometry with a 0.8 mm corner radius concentrates cutting forces favourably for external and internal turning, helping to deliver consistent surface finish and tool-run stability. The integrated TUS chipbreaker shapes chips for reliable evacuation at common turning parameters, lowering the risk of entanglement in bores or on long parts. The combination of rhombic form and dedicated chip control supports both general-facing and profilng operations while reducing vibration-related issues, especially when paired with appropriate holder rigidity.

Operational advantages and selection guidance for turning tasks

As an indexable insert for turning, the component fits into a system comprising insert, matched holder or bar, underlay/shim and fasteners; the choice of chipbreaker and grade should match workpiece material and whether the cut is continuous or intermittently interrupted. For medium steels, the T9215 grade with TUS breaker generally yields a good compromise between productivity and edge security. Component manufacturers benefit from reduced changeover time, predictable insert life and consistent part quality, supporting lean processes and lower per-part tooling costs.
