SNMG 120412 T9225 turning insert for turning – Tungaloy

SNMG120412 T9225 is an ISO-compatible, CVD-coated cemented-carbide turning insert designed for medium to heavy steel turning and intermittent cuts

• ISO SNMG 120412 geometry, square form
• CVD-coated cemented carbide T9225 grade
• Robust for medium to heavy steel turning
• Double-sided chipbreaker, 0° clearance

Consistent clamping and predictable cutting performance

The ISO indexable geometry of this square insert ensures reliable positioning in standard holders and repeatable results in series production. The insert’s compatibility with a toolholder is defined by its form, clearance angle, tolerance class, attachment style, size and thickness; this predictability reduces setup time and simplifies tool management. The square form and central cylindrical hole support positive clamping and secure fixation, helping to maintain concentricity during external and internal turning operations.

Grade and coating engineered for demanding steel turning

The CVD-coated cemented-carbide grade T9225 is a universal, toughness-orientated sort developed for the mid to heavy end of steel machining. Its coating improves wear resistance while the substrate provides the required fracture toughness for slightly interrupted cuts and variable engagement conditions. As a result, the insert offers a balanced combination of chip control and edge stability, translating into longer in-process life and fewer unplanned indexings in production workflows.

Practical handling that supports productivity and economy

A double-sided chipbreaker and a 0° clearance design increase available cutting edges per insert, lowering tooling costs per component and enabling quick index changes. The rounded corner with a 1.2 mm radius helps distribute cutting forces and improves surface finish on general turning tasks. With a nominal plate size of 12 mm and a thickness of 4.76 mm, the insert fits common ISO plates and provides a compact solution where tool stiffness and fixture space are considerations. The result is a pragmatic insert that aids consistent cycle times and simplified logistics on the shop floor.

FAQ

Is this insert suitable for interrupted cuts?
Yes. The T9225 grade and its cemented-carbide substrate are formulated to provide extra toughness for slightly interrupted or variable engagement conditions with the SNMG120412 insert.

What material is the cutting substrate and coating?
The SNMG120412 insert uses a cemented-carbide substrate with a CVD-coated surface in the T9225 grade to improve wear resistance and edge life during steel turning.

How many cutting edges are available per insert?
This is a double-sided, square insert; each side provides multiple indexable edges, increasing cost efficiency per edge compared with single-sided options.

Which toolholders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; the SNMG120412 geometry matches standard ISO SNMG holders with a cylindrical-hole clamping system.

What are the key dimensions to check when selecting a holder?
Verify plate size (12 mm), thickness (4.76 mm), corner radius (1.2 mm) and the presence of the cylindrical hole to ensure proper seating and secure clamping for the SNMG120412 insert.
