CNMG 120408 T9215 Tungaloy turning insert — CVD-coated carbide, rhombic 80° geometry

The CNMG120408 T9215 is an ISO rhombic indexable turning insert designed for external and internal turning of medium steels, offering a balance of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215 for medium steel
• Rhombic insert, 80° cutting geometry
• 0.8 mm nose radius for versatile turning
• Double-sided insert with cylindrical hole

Productivity and process reliability for medium steel turning

The combination of a CVD-coated surface with a tough carbide substrate delivers measurable wear resistance and edge stability under standard production feeds. This makes the insert particularly suitable where consistent cutting performance is required over extended runs. The cutting geometry provides a predictable chip flow and reduced flank wear, supporting reliable cycle times and helping to maintain dimensional tolerance in series machining.

Compatibility and system guidance for safe tool selection

Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening, size and thickness; the insert is part of a complete system comprising the indexable plate, a matching external holder or boring bar, a shim/clamp set and replacement screws. Specifying the correct holder form and clamping arrangement ensures optimal seat stability and repeatable positioning, which in turn reduces vibration and the risk of premature edge failure during turning.

Practical advantages of the T9215 grade in production

Grade T9215 has been selected for its blend of abrasive wear resistance and fracture toughness, offering an effective solution for mid-range steels where moderate interruptions and varying engagement conditions occur. The result is increased tool life and fewer insert changes, contributing to improved throughput and reduced downtime in the machining cell. The double-sided design also extends usable life per insert by permitting indexed re-use of the second cutting edge.

Key geometric and handling details explained

The rhombic form with an 80° cutting angle and a 0° relief works well for general turning profiles, while the 0.8 mm nose radius balances edge strength and surface finish capability. A plate thickness of 4.76 mm and the presence of a cylindrical locating hole provide secure clamping and straightforward indexing. Such nominal values are useful when matching inserts to existing holders or when establishing cutting parameters for process planning.

FAQ

What materials is this insert intended for?
The CNMG120408 T9215 insert is intended primarily for medium steels; the T9215 grade combines wear resistance and toughness suited to common turning applications in steel.

How does the CVD coating benefit performance?
A CVD-coated surface improves abrasive wear resistance and thermal stability, helping the insert maintain cutting-edge integrity and supporting longer tool life under typical turning conditions.

Is the insert single- or double-sided, and what does that mean for tool life?
This is a double-sided indexable plate, which allows the use of two cutting edges before disposal, effectively doubling the number of available cutting edges per insert and increasing life-cycle value.

Which holder characteristics must be checked for compatibility?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; ensuring these parameters match prevents incorrect seating and preserves cutting performance.

Can this insert handle slightly interrupted cuts?
Yes, the T9215 grade and robust carbide substrate offer fracture resistance suitable for continuous to slightly interrupted cutting regimes, helping to maintain productivity with minimal edge breakage.
