SNMG 120408 T9235 Wendeplatten - Tungaloy

The combination of a CVD-coated carbide grade formulated for steel and a 0.8 mm corner radius provides robust performance in unstable turning conditions, while the ISO square geometry and double-sided chipbreaker support repeatable fitment and easy indexing; order the insert directly via Metav Werkzeuge or consult the Metav team for application advice.

SNMG 120408 T9235 Tungaloy indexable insert — ISO turning insert, 0.8 mm radius, CVD-coated carbide

The SNMG120408 T9235 is a square, ISO-standard indexable insert designed for external and internal turning, offering a tough CVD-coated carbide grade for stable cutting of steel in interrupted or less rigid conditions.

• ISO-standard square insert, 90° geometry
• CVD-coated carbide grade T9235
• 0.8 mm corner radius for robust edges
• Double-sided chipbreaker, cylindrical hole

Reliable cutting for demanding steel turning

The insert is manufactured from CVD-coated carbide, offered under the T9235 designation, which is formulated as a tough grade for machining steel at moderate cutting speeds and in less stable setups. The CVD coating increases wear resistance on the rake and flank faces, so the tool maintains cutting performance longer in interrupted cuts and rougher conditions. For production environments where tool life and predictable change intervals matter, this combination reduces unplanned stoppages and supports consistent cycle times. The technical composition balances hardness and toughness to limit chipping while preserving edge integrity under plunge or interrupted operations.

ISO geometry for predictable fit and repeatability

As an ISO-format square insert with an included angle of 90° and size 12 mm, the SNMG120408 follows established standards that simplify holder selection and bench-to-bench interchangeability. The 0° rake angle and a nominal thickness of 4.76 mm ensure the insert seats securely in most standard clamping systems; the central cylindrical hole supports positive screw fixing. Standardised dimensions mean quick tool changes and straightforward inventory management, helping workshops maintain process stability and reduce setup time. Clear identification by the ISO designation also aids in ordering and traceability across work centres.

Effective chip control and edge security for unstable cuts

The double-sided chipbreaker design provides improved chip formation and evacuation on both indexing positions, which is especially valuable when turning where rigidity fluctuates or the cut is interrupted. The 0.8 mm corner radius offers a compromise between edge strength and surface finish: it protects the cutting edge against shock loads while still producing a consistent external profile. Together, chip control and corner geometry support a stable cutting action that can improve surface quality on the workpiece and reduce rework, delivering measurable productivity benefits in serial and job-shop settings.

Practical system integration and selection guidance

The insert is intended as part of a complete system consisting of the ISO insert, a matching external holder or boring bar, and the appropriate shim/clamping set with replacement screws. Compatibility with a given holder is determined by form, clearance/rake angle, tolerance class, fastening method, size and thickness; these parameters should be checked against the machine setup before procurement. When selecting a chipbreaker and grade, match them to the workpiece material, machining strategy and machine stability to obtain the best balance of productivity and tool life. For specification support, technical datasheets and cutting parameter recommendations are available from Metav Werkzeuge.

FAQ

What materials is this insert primarily intended for?
The SNMG120408 T9235 insert is formulated for machining steel; the T9235 grade is a tougher CVD-coated carbide designed for lower cutting speeds and interrupted or unstable cutting conditions.

Will the SNMG120408 fit standard SNMG holders?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening type, size and the insert thickness; the SNMG120408 follows ISO dimensions to ensure fitment with matching ISO holders when those parameters align.

Is the insert suitable for interrupted machining and unstable setups?
Yes. The T9235 tough grade together with the 0.8 mm corner radius and a double-sided chipbreaker gives improved resistance to edge chipping and better chip control in interrupted cuts and less rigid conditions.

How should the insert be supplied as a system?
A complete setup typically comprises the ISO insert, a suitable external holder or boring bar, a shim/clamping set and the corresponding replacement screws; selecting the correct clamping components ensures stable fixation and repeatable positioning.

Where can cutting parameters and mounting advice be obtained?
Cutting data sheets and mounting guidelines are provided for the SNMG120408 T9235 insert; Metav Werkzeuge can supply recommended parameters and application support for efficient integration.
