SNMG120416 T9215 Tungaloy turning insert — ISO insert for turning applications

SNMG120416 T9215 Tungaloy turning insert is an ISO‑standard, square indexable insert designed for external and internal turning in medium‑steel machining.

• CVD-coated carbide T9215
• High wear resistance and toughness
• For medium steel turning applications
• Double-sided chipbreaker with cylindrical hole

Reliable performance for medium steel turning

The CVD‑coated carbide grade T9215 combines elevated wear resistance with good fracture toughness, making it especially suitable for productive, continuous to lightly interrupted turning operations in medium‑strength steel. The coating reduces flank wear and extends edge life under stable cutting conditions, which translates into longer tool life and fewer indexings. This grade is optimised for a balance between abrasion resistance and edge stability, enabling higher material removal rates where consistent surface quality and repeatable part tolerance are priorities.

Clear design features and holder compatibility

The ISO designation indicates a square plate with the common SNMG form and the specific size code 120416, which corresponds to a nominal 12 mm plate size, 4.76 mm thickness and a 1.6 mm corner radius. The insert has a 0° rake angle and a 90° included angle, with a cylindrical central hole for secure clamping. Compatibility with a toolholder is determined by the insert form, relief angle, tolerance class, fixing method, size and thickness; matching these parameters to the holder ensures correct seating and repeatable positioning. SNMG120416 inserts therefore integrate into standard ISO turning systems with the appropriate clamping kit and screw.

Effective chip control and machining stability

A double‑sided chipbreaker provides controlled chip formation on each index, helping to maintain process stability and reduce the risk of chip entanglement. This characteristic supports efficient machining in continuous cuts and short, lightly interrupted cycles, improving surface finish and reducing cycle time. Choosing the correct chipbreaker geometry and matching the T9215 grade to the workpiece material and cutting parameters will maximise tool life and deliver consistent production results. For operations with heavier interruptions or atypical alloy compositions, selection of an alternative chipformer or grade should be considered.

FAQ

What materials is this insert best suited for?
The SNMG120416 T9215 Tungaloy insert is optimised for medium‑strength steel machining, offering a balance of wear resistance and toughness suitable for productive turning operations.

Can the SNMG120416 be used for interrupted cuts?
Yes, the T9215 grade tolerates light to moderate interruptions thanks to its fracture‑resistant edge, but heavy interruptions may require a different grade or reinforced cutting strategy.

How is the insert secured in the holder?
The insert is designed for ISO‑compatible holders and is clamped via its cylindrical central hole; correct holder geometry, tolerance and clamping hardware ensure stable seating and repeatable positioning.

Does the double‑sided chipbreaker affect indexability?
The double‑sided chipbreaker provides two usable cutting edges per indexing position, enabling predictable chip control and more efficient use of the insert before regrind or disposal.

Which cutting conditions maximise tool life with this grade?
Using stable cutting parameters with steady feed and optimised cutting speed for medium steel, combined with appropriate coolant or minimum quantity lubrication, will extend the life of the SNMG120416 T9215 insert.
