Walter 5691411 Turning Insert CNMG431-NFTWS10 Carbide

Product Description

The WALTER 5691411 is a solid carbide uncoated turning insert in the CNMG431-NFT geometry, designed for precision metal cutting on CNC lathes and turning centers. Carrying the WS10 grade designation, this insert targets superalloys and titanium as its primary workpiece materials - demanding applications where edge sharpness and substrate toughness matter more than coating. The 80-degree diamond insert shape provides a strong cutting geometry, while the NFT chip breaker is configured for negative rake turning with a sharp cutting edge style. With four available cutting edges per insert, this is a productive choice for shops running high-value aerospace and energy-sector components.

This insert is suited for turning, facing, and boring operations on difficult-to-machine materials including superalloys and titanium. The neutral hand orientation makes it adaptable across a range of toolholder setups. The CNMG form factor fits standard CNMG-style toolholders used on both manual and CNC turning equipment. It is installed and indexed by licensed machinists and tool-and-die professionals working in tight-tolerance production environments where surface integrity and dimensional accuracy are critical.

Key Features

• 80-degree diamond insert shape (CNMG style) delivers strong nose geometry with 1/64 inch corner radius
• Four cutting edges per insert for cost-effective indexing
• Neutral hand orientation compatible with standard CNMG clamp-and-pin toolholders
• Multi-use application: turning, facing, and boring in a single insert geometry

Compatibility

Designed for use in standard CNMG-style clamp-and-pin toolholders accepting a 1/2 inch inscribed circle insert. Conforms to ANSI and ISO standards; ISO code CNMG120404-NFT WS10, industry standard number CNMG431-NFT WS10.

Installation Notes

Installation is performed by a qualified machinist following machine tool manufacturer guidelines. Always power down and lock out the machine spindle before indexing or replacing inserts. Inspect the toolholder seat and clamping components for wear or debris before seating the insert. Confirm correct insert orientation and secure clamping torque per the toolholder manufacturer specifications before resuming cutting operations.
