SCGT09T308-MN2 WNN10 turning insert — square 90°, MN2 chipbreaker, Walter Tools

The SCGT09T308-MN2 WNN10 is a square, coated carbide turning insert for general turning and facing tasks, designed to deliver predictable chip control and consistent edge strength in production environments.

• Coated carbide grade WNN10
• MN2 chipbreaker for consistent chips
• Square 90° geometry for facing and turning
• Corner radius 0.8 mm for robust cutting edge

Increased throughput through controlled chip formation

The design centres on efficient material removal: the MN2 chipbreaker produces small, manageable chips that reduce rework and improve cycle times. Combined with the coated carbide grade identified as WNN10, the insert offers wear resistance suited to serial machining. This results in fewer interruptions for tool changes and a steadier production flow, supporting higher productivity in turning operations.

Stable tool life from robust geometry and relief

A square 90° insert geometry with a 0.8 mm corner radius and a 7° relief angle delivers a balance between edge strength and accurate profile control. The slightly positive relief reduces cutting forces while the corner radius supports edge integrity during interrupted cuts, giving repeatable performance across batches. These geometric choices help maintain dimensional accuracy and extend service intervals for tooling systems.

Selection guidance and compatibility notes

The grade WNN10 is a coated cemented carbide; suitability for specific workpiece materials should be verified against the manufacturer’s application matrix. The item is specified as catalogue-dependent for base material information, so verify the exact material version when planning an operation. For specialised materials or alternative chip control needs, consider matching the chipbreaker and insert size to the lathe capacity and the intended feed and depth of cut.
