SNMG120408 GT9530 indexable turning insert for ISO-standard finishing – Tungaloy

A SNMG120408 GT9530 indexable insert for ISO-standard turning, engineered for finishing and light universal machining of steel components.

• SNMG120408 format for ISO-standard holders
• Coated cermet grade GT9530 for longer life
• Double-sided chipbreaker for consistent chips
• Square insert with 0.8 mm nose radius

Consistent finishing and extended tool life

The coated cermet grade GT9530 provides a balance between wear resistance and surface integrity, making it suitable for finishing cuts under stable conditions. The coating reduces flank wear and enables longer intervals between indexings, which supports production continuity and lowers lifecycle costs. For operations demanding good surface quality on steel, the insert’s material and coating combination delivers measurable improvements in repeatability and component appearance.

Accurate fit and practical fixture guidance

Designed as an ISO-standard insert, the SNMG120408 ensures compatibility with ISO holders when form, clearance angle, tolerance class, fastening, size and thickness are matched. The square plate geometry and the 90° main cutting angle enable predictable engagement in outside and inside turning. The specified 0° clearance and the 0.8 mm nose radius are factors to consider when selecting depth of cut and feed for finishing passes to maintain dimensional accuracy and edge stability.

Effective chip control and application range

The double-sided chipbreaker balances chip formation for finishing and light universal turning, promoting stable evacuation and reduced vibration. Manufactured from cemented carbide, the insert resists abrasive wear and maintains cutting-edge integrity under consistent cutting conditions. Typical applications include external and internal turning of steel components where a fine surface finish and longer tool life are priorities; choose the chipbreaker and grade to match the workpiece material and machine stability.

Practical notes on setup and substitution

Compatibility depends on insert form, thickness (4.76 mm), size (12 mm), hole style and mounting; the SNMG120408 comes with a cylindrical centre hole for secure fastening. When replacing tools, ensure the holder tolerances and clamping parts are suitable to preserve cutting geometry and to avoid chattering.
