Walter 5381296 CNMG432-NFTWS10 Carbide Turning Insert

Product Description

The WALTER 5381296 is a solid carbide turning insert designed for precision metal cutting in demanding machining operations. Manufactured to the CNMG432-NFT WS10 industry standard, this insert features an 80-degree diamond shape with a negative rake geometry and a sharp cutting edge style. The WS10 uncoated carbide grade is engineered specifically for cutting superalloys and titanium, where coating adhesion and heat management at the edge are critical. With four usable cutting edges and a neutral hand orientation, this insert delivers consistent performance across turning, facing, and boring applications. It is sized with a 0.5-inch inscribed circle and a 0.0315-inch corner radius.

This insert is intended for use on CNC lathes and turning centers in industrial machining environments. Its primary application is finishing and semi-finishing cuts in superalloys and titanium, making it a common choice in aerospace, medical device, and high-performance component manufacturing. The NFT chip breaker geometry supports chip control in tough, stringy materials. It is suitable for turning, facing, and boring operations and conforms to both ANSI and ISO standards. The ISO code for this insert is CNMG120408-NFT WS10.

Compatibility

Designed as an OEM-style replacement or direct-fit turning insert for toolholders accepting CNMG432 (CNMG120408) style inserts with clamp or pin retention. Conforms to ANSI and ISO CNMG120408-NFT WS10 standards. Multi-use application includes turning, facing, and boring.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert seat and clamp for wear or debris before seating a new insert to ensure proper edge presentation and prevent premature failure.
