SNMG 120408 T9225 indexable turning insert — Tungaloy, CVD-coated carbide for medium–heavy steel turning

SNMG 120408 is an ISO-format, square indexable insert designed for external and internal turning where a tough, versatile grade is required.

• CVD-coated carbide grade T9225
• Robust universal grade for medium–heavy steel
• Double-sided chipbreaker for longer use
• Square SNMG insert with 0.8 mm corner radius

Consistent productivity for mixed turning tasks

The SNMG120408 insert is engineered to deliver stable cutting performance in changing engagement conditions. Its CVD-coated carbide substrate and the T9225 grade offer an optimum balance between hardness and toughness, which reduces flank wear while resisting chipping during interrupted cuts. This results in fewer insert changes and a more predictable production rhythm, supporting higher machine uptime and improved throughput in batch and single-piece flow alike.

Design details that simplify process planning

The square geometry with a 0.8 mm corner radius and a 90° included angle provides a clear mix of strength and accessibility for finishing and light roughing passes. The double-sided chipbreaker enhances chip control and contributes to consistent surface quality; when combined with the ISO format, it eases inventory management since the insert fits widely used SNMG holders. Dimension and relief specifications follow ISO standards, so selection of the correct holder is primarily guided by form, clearance angle, tolerance class, mounting method and thickness.

Practical use and economic advantage in steel machining

For turning of medium to heavy steels, the T9225 grade is formulated to tolerate slightly interrupted cuts and variable stability at the tool tip, offering longer life than more brittle grades in comparable conditions. Fewer tool changes reduce handling time and scrap risk. When paired with an appropriately rigid holder and optimised cutting data, the insert supports improved process reliability and consistent surface finish, helping to lower overall manufacturing cost per component while maintaining machining precision.
