SNGG 120408 X407 — Tungaloy indexable insert for turning (ISO 120408)

The SNGG120408-01 X407 is a square ISO‑compliant indexable insert engineered for external and internal turning, offering a balanced mix of wear resistance and edge stability.

• ISO‑compliant square geometry
• Grade X407 for wear resistance
• 0.8 mm corner radius for fine turning
• Cylindrical hole for secure clamping

Consistent cutting performance for higher productivity

The insert is made from carbide and specified in Grade X407, a Tungaloy development that balances wear resistance and toughness to maintain a stable cutting edge over extended runs. With a 0.8 mm corner radius and a 90° included angle, the geometry supports repeatable dimensional control during face and profile turning. The combination of the material and geometry reduces unexpected tool changes and contributes to a predictable tool life, which makes process planning and cycle-time calculations more reliable for production environments.

Compatibility that simplifies toolholder selection

This ISO indexable format follows the ISO 120408 designation and is compatible with holders that match form, relief angle, tolerance class, fastening style, size and thickness. The square format and the cylindrical hole ensure positive mechanical location and secure clamping in suitable external holders or boring bars. The 4.76 mm plate thickness and 12 mm size are standard dimensions that ease inventory management and replacement logistics. Selecting the correct chipbreaker 01 and matching the insert grade to the workpiece material delivers improved chip control and surface finish without overcomplicating fixture choice.

Practical guidance for selection and process reliability

For turning applications, consider the workpiece material and required stability when choosing this insert: Grade X407 is designed to complement the insert geometry with a focus on edge integrity under moderate to demanding conditions. The 0° relief angle supports general turning operations, while the chipbreaker 01 is intended for effective chip formation in a range of steels and mixed materials. If further specification is needed—for example, optimising feed and speed for a particular alloy—our team can provide tailored recommendations to ensure the insert delivers consistent component quality and minimal downtime.

FAQ

What work is this insert intended for?
The SNGG120408-01 X407 Tungaloy indexable insert is intended primarily for external and internal turning; it is supplied in a square ISO format suitable for a wide range of turning tasks.

Which materials suit Grade X407 best?
Grade X407 provides a balanced combination of wear resistance and toughness, making the insert appropriate for a broad coverage of steels and mixed materials where edge stability and consistent tool life are required.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius offers a compromise between strength and finishing capability: it improves edge robustness compared with smaller radii while still enabling fine surface quality on turned components.

Is the insert compatible with standard ISO holders?
Yes—the ISO designation and the cylindrical hole allow this insert to be mounted in holders that match the form, size, fastening and tolerance requirements described by the ISO system.

What does chipbreaker 01 mean for chip control?
Chipbreaker 01 is engineered to produce controlled chips for typical turning operations; when combined with the X407 grade and correct cutting parameters it supports safe evacuation and improved surface finish.
