SCGT09T304-FN2 WNN10 – Indexable turning insert, square 90°, 0.4 mm corner radius (Walter Tools)

The SCGT09T304-FN2 WNN10 is a square 90° indexable turning insert intended for precision external turning where reliable chip control and stable cutting edges are required

• Coated carbide grade WNN10
• Square 90° insert for stable clamping
• FN2 chipbreaker for controlled chips
• 0.4 mm corner radius, 7° clearance angle

Productive cutting with proven coated carbide

The combination of a coated carbide substrate and the WNN10 grade is designed to deliver predictable performance under standard turning conditions. The FN2 chipbreaker assists in producing short, manageable chips, reducing interruptions in automated setups and lowering the risk of entanglement or component damage. This combination aims to improve tool utilisation and contribute to smoother production flow by limiting unplanned stoppages. The data supplied with the insert should be consulted alongside the machine and process parameters to calculate achievable cutting speeds and feeds for specific tasks.

Stable edge geometry for consistent part quality

A square 90° form combined with a 0.4 mm corner radius provides a good balance between edge strength and surface finish. The modest radius increases resistance to chipping while still allowing acceptable surface quality on turned components, particularly in operations that demand repeatable results. The 7° clearance angle reduces rubbing at the flank and helps maintain dimensional accuracy over longer tool life. The insert’s T3 thickness contributes to clamping stability in standard toolholders, supporting vibration damping and consistent cutting conditions.

Straightforward integration and process security

The SCGT format ensures compatibility with many standard turning toolholders, facilitating quick retrofits without complex tool changes. The designation SCGT09T304-FN2 identifies the geometry and chipbreaker, while the WNN10 marking denotes the coated hardmetal grade; however, the exact substrate and coating characteristics may be catalogue-dependent, so verification against the product matrix is recommended. Where process reliability is critical, combining this insert’s chip control with appropriate cutting parameters promotes predictable metal removal and less scrap, supporting economic machining.

Selection guidance and application notes

Material suitability should be checked in the manufacturer’s product matrix because the WNN10 coated grade is optimised for a defined range of applications and workpiece materials. For new applications or mixed-material production, a short trial under representative conditions is recommended to validate feeds and speeds. The open series designation indicates flexibility in ordering variants; technical documentation provides the precise coating and substrate details. For customers seeking process stability and clear documentation, the insert supports structured tool selection and traceable setup records.

FAQ

What materials is this insert best suited for?
Material suitability for the SCGT09T304-FN2 WNN10 insert should be confirmed in the manufacturer’s product matrix; the WNN10 designation indicates a coated hardmetal grade tailored for a defined range of turning tasks

How does the FN2 chipbreaker affect machining?
The FN2 chipbreaker on the SCGT09T304-FN2 promotes controlled, short chip formation, improving handling in automated or multi-station lathes and reducing the likelihood of chip-related interruptions

Can the insert be used in standard SCGT toolholders?
Yes, the insert’s SCGT format and T3 thickness are compatible with common SCGT toolholders, offering straightforward integration and stable clamping for routine turning operations

What benefit does the 0.4 mm corner radius provide?
A 0.4 mm corner radius increases edge strength and resistance to chipping, supporting consistent surface quality while maintaining acceptable cutting forces for typical turning cycles

Is the coating and substrate consistent across all batches?
The WNN10 grade is a defined coated hardmetal class, but precise substrate and coating details are catalogue-dependent; consult the technical datasheet or product matrix for batch-specific information
