SNMG 120412 T9235 square turning insert for turning — Tungaloy

A SNMG120412 T9235 ISO-format square indexable insert designed for external and internal turning, offering a robust edge for interrupted cuts and unstable machining conditions

• CVD-coated carbide grade T9235 suited for steel
• Double-sided chipbreaker for versatile use
• Square 12 mm insert with 90° cutting angle
• 1.2 mm corner radius for a strong cutting edge

Built for reliable cutting in unstable conditions

The CVD-coated carbide grade T9235 provides a balance between toughness and wear resistance, making it well suited to steel machining at lower cutting speeds and in situations with interrupted cuts. The coating enhances edge life by resisting adhesion and abrasive wear, which contributes to fewer insert changes and more consistent cycle times. This combination of material and coating supports process stability when machine conditions are less rigid, translating into measurable improvements in uptime and tool-change frequency.

Geometry that protects the edge and ensures versatility

The square format together with a 90° cutting angle and a 1.2 mm corner radius yields a robust tool edge that tolerates heavier engagement and offers predictable chip flow. The insert is double-sided, effectively doubling indexable edges and reducing inventory turnover. A 4.76 mm plate thickness and a cylindrical hole ensure secure clamping in compatible holders, while the 0° rake angle supports controlled cutting forces in roughing passes. These geometric choices simplify tool selection for mixed turning tasks and help maintain dimensional accuracy across varying workpiece setups.

ISO compatibility and system-level benefits

As part of an ISO turning insert system, compatibility with the toolholder is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness. Selecting the appropriate chipbreaker and grade for the workpiece and stability conditions optimises both surface finish and tool life. The indexable format supports fast reindexing and minimal downtime, improving productivity in batch production and repair jobs alike. If further matching of holder and insert is required, specialist advice is available by phone or email to ensure correct integration.

If uncertain whether this insert matches a specific job, the data sheet and application notes help guide selection; alternatively, Metav Werkzeuge’s technical team is available to advise on holder compatibility, cutting parameters and grade selection.

FAQ

What materials is this insert optimised for?
The T9235 grade is formulated for machining steel, particularly where low cutting speeds, interrupted cuts or unstable setups occur; the SNMG120412 T9235 insert benefits from the CVD coating for improved wear resistance.

How is compatibility with toolholders determined?
Compatibility depends on insert form, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation indicates standardised dimensions for matching holders and clamping systems.

Can this insert be used for internal turning as well as external turning?
Yes — the square ISO insert is suitable for both external and internal turning operations when paired with an appropriate holder and clamping arrangement.

What operational advantages does the double-sided chipbreaker provide?
A double-sided chipbreaker extends usable edges per insert, reduces changeovers and offers flexibility in chip control across roughing and finishing operations.
