SNMG 120408 T9225 SNMG turning insert by Tungaloy — CVD-coated carbide, 0.8 mm radius

SNMG120408 T9225 is an ISO-standard square indexable turning insert designed for robust performance in steel turning applications, combining a tough CVD coating with geometry suited to variable engagement conditions

• ISO-standard square indexable insert SNMG
• CVD-coated carbide grade T9225
• 0.8 mm corner radius for controlled finish
• Double-sided chipbreaker for consistent chips

Consistent cutting performance for medium to heavy steel turning

The combination of CVD-coated carbide and the T9225 grade delivers a balance of wear resistance and toughness that is particularly effective in medium to heavy steel turning. This material and coating choice improves tool life under variable cutting conditions and when brief interruptions in the cut occur. The corner radius 0.8 mm helps to maintain edge stability and surface finish, reducing the need for frequent edge changes and supporting a more economical production flow.

Secure clamping and ISO compatibility for repeatable set-ups

The insert's square form with a 90° shape and the specified dimensions ensure compatibility with ISO holders when the shape, relief angle, tolerance class, clamping and thickness match the toolholder. The 0° relief angle and the cylindrical hole support reliable locating and repeatable seating in the pocket, which reduces run-out and supports consistent cutting forces. This geometry simplifies set-up checks and contributes to predictable, repeatable machining results.

Predictable chip control and tool system integration

With a double-sided chipbreaker and a plate thickness of 4.76 mm, the insert is designed to manage chips effectively across a range of feeds and depths, helping to avoid built-up edge and to maintain reproducible surface quality. The insert is intended to be used within a complete system comprising the ISO indexable insert, a matching external holder or boring bar, and the correct underlay/clamping set with replacement screws. This system approach supports safe clamping, quick indexability and reduced process downtime.

FAQ

What steels is this insert designed for?
The SNMG120408 T9225 Tungaloy insert is formulated for medium to heavy steel turning, offering a balance of toughness and wear resistance suited to varying engagement conditions.

How does the T9225 grade affect tool life?
The T9225 CVD-coated carbide grade emphasises toughness and stable chip formation; in practice this leads to longer tool life under interrupted cuts and more consistent performance compared with less tough grades.

Is the insert compatible with standard SNMG holders?
Compatibility depends on holder specifications; the insert follows ISO SNMG geometry, so matching shape, relief angle, tolerance class, clamping, size and thickness with the holder ensures correct fit and repeatability.

How many usable edges does the insert provide?
The insert features a double-sided chipbreaker and square form, allowing indexability and multiple cutting edges per insert depending on the mounting and indexing practice used in the tool system.

What components are required for a complete tool assembly?
A complete assembly includes the ISO indexable insert, a suitable external holder or boring bar, the correct underlay/clamping set and appropriate replacement screws to secure the insert reliably.
