SNMG120408 T9235 indexable turning insert — CVD-coated carbide, 0.8 mm radius, by Tungaloy

A SNMG120408 T9235 indexable insert designed for external and internal turning, optimised for steel machining under unstable or interrupted cutting conditions

• SNMG120408 format, ISO 120408
• CVD-coated carbide grade T9235
• 0.8 mm corner radius for robust edge
• Double-sided chipbreaker, cylindrical hole

Reliable cutting performance for demanding turning applications

The CVD-coated carbide grade T9235 provides a tough cutting edge that is particularly suitable for machining steel at reduced cutting speeds and where interruptions or variable engagement occur. This characteristic reduces the risk of premature edge chipping and contributes to a more consistent machining process. By selecting a grade matched to the workpiece and cutting conditions, tool life becomes more predictable and component rework is reduced, supporting uninterrupted production and cost-effective throughput.

Secure system compatibility and simple mounting for stable runs

Compatibility with toolholders is determined by insert form, clearance angle, tolerance class, attachment, size and thickness; the ISO format ensures straightforward matching to standard holders. The SNMG geometry with a 90° approach angle and a 0° clearance specification is compatible with many common external and internal turning holders. A system comprises the indexable insert, a suitable external holder or boring bar, a shim/clamp set and replacement fixing screws, which together guarantee secure seating and repeatable positioning for reliable part-to-part accuracy.

Consistent chip control and edge security for mixed conditions

The square form combined with a 0.8 mm corner radius supports robust edge strength, while the double-sided chipbreaker helps fragment chips in interrupted cuts and under unstable feeds. The cylindrical locating hole provides positive positioning and straightforward clamping, which is particularly valuable when rapid indexing is required. The result is improved surface finish and reduced vibration, which benefits downstream processes by lowering inspection rejects and enhancing overall productivity.

Practical use, selection advice and application range

This insert is intended primarily for turning steel where a tougher grade is advantageous over high-speed grades. Select the appropriate chipbreaker and cutting data depending on material, cutting speed and machine rigidity; for heavily interrupted cuts, the T9235 grade offers increased edge security at moderated speeds. For further specification checks or to confirm holder compatibility, technical details such as insert thickness 4.76 mm, size 12 mm and the ISO designation should be checked against the toolholder data sheet to ensure a correct fit.

FAQ

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

How is compatibility with existing toolholders ensured? Compatibility is determined by the insert form, clearance angle, tolerance, attachment, size and thickness; check the ISO 120408 dimensions and the insert thickness 4.76 mm against the holder specification to ensure a correct match.

What advantage does the double-sided chipbreaker offer? A double-sided chipbreaker provides chip-control versatility and allows the insert to be indexed to a fresh cutting edge, improving chip formation and contributing to more consistent surface quality during intermittent cuts.

Can the SNMG120408 be used for internal turning as well as external turning? Yes, the ISO SNMG120408 geometry is suitable for both external and internal turning when combined with the appropriate boring bar or holder designed to accept ISO-format square inserts.
