SNMG 120404 T9225 turning insert — Tungaloy indexable insert with CVD-coated carbide

SNMG 120404 T9225 is an ISO-standard, square turning insert designed for medium to heavy steel machining, offering a robust universal grade and a double-sided chipbreaker for consistent chip control

• CVD-coated carbide Grade T9225
• Square 90° geometry with 0° relief
• Double-sided chipbreaker for stable chips
• Four usable cutting edges per insert

Reliable cutting performance for demanding steel turning

The CVD-coated carbide of the T9225 grade combines wear resistance with enhanced toughness, making the insert particularly suited to medium to heavy steel operations where cutting conditions can vary. The coating improves abrasion resistance while the substrate provides necessary strength for slightly interrupted cuts, so the result is longer effective tool life and consistent surface quality. For shops seeking predictable process performance, this balance reduces unscheduled tool changes and supports steady production runs.

Secure seating and geometry that stabilise cutting

Built to ISO dimensions, the square 90° geometry with a 0° relief provides a neutral, negative-style insert that seats firmly in standard external holders or boring bars. The cylindrical hole and standard thickness ensure compatibility with clamping sets and replacement screws, while the defined corner radius 0.4 mm helps achieve repeatable part geometry. This mechanical fit reduces vibration and improves dimensional repeatability when paired with a suitable holder, translating into fewer rejects and faster set-up validation.

Productivity through multiple edges and optimised chip control

The double-sided chipbreaker geometry gives two usable faces per side, yielding multiple indexing positions and therefore four cutting edges overall. This configuration lowers tooling consumption per edge and improves cost efficiency over time. The chipbreaker is designed to produce controlled swarf when working with steel, supporting safe chip evacuation and steady cutting forces. As a result, cycle times remain stable and component finish is easier to achieve without complex parameter changes.

Application guidance and matching to holders

Designed for general-purpose turning, the insert performs well in both external and internal turning when paired with the correct holder and cutting data. Compatibility is determined by insert form, clearance angle, tolerance class, fastening and thickness; selecting a holder that matches the ISO SNMG form and that offers rigid clamping will unlock the full potential of the grade. For mixed-production environments the universal nature of T9225 simplifies inventory while providing good all-round performance.
