Walter 5025571 Turning Insert Ccgt 80 Diamond Carbide

Product Description

The WALTER 5025571 is a solid carbide turning insert designed for precision metal removal in turning, facing, and boring operations. It carries a TiCN Plus PVD coating applied via physical vapor deposition, which supports sharp cutting edge retention across a range of workpiece materials. The insert geometry follows the CCGT style with an 80-degree diamond (rhombic) shape, a positive rake angle of 25 degrees, a 7-degree relief angle, and a positive side clearance. With a 0.008 inch corner radius and two available cutting edges, it suits light to medium material engagement where edge sharpness and surface finish are priorities.

This insert is rated primarily for non-ferrous metals and secondarily for steel and stainless steel. The PM2 chip breaker geometry supports roughing and medium machining operations. It is appropriate for CNC lathes and turning centers in production environments where consistent chip control and coating durability are required. The screw-clamping holding method keeps the insert securely indexed during multi-pass operations.

Key Features

• TiCN Plus PVD coating for wear resistance on non-ferrous and steel workpieces
• 80-degree diamond (rhombic) CCGT insert shape with positive rake and positive side clearance
• PM2 chip breaker geometry rated for roughing and medium machining
• Sharp cutting edge style suited to finishing passes on non-ferrous materials
• Two cutting edges per insert for extended tool life per unit
• Screw-mount holding method for secure, repeatable indexing

Compatibility

Designed for use in toolholders conforming to ANSI insert code CCGT32.50.5 and ISO insert code CCGT09T302. Verify that the target toolholder specifies CCGT geometry, 3/8 inch inscribed circle, and screw-clamp retention before installing.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the clamping screw - do not overtighten, as carbide inserts are brittle and can fracture under excess clamp load. Confirm seating of the insert in the pocket before resuming operation, and verify that chip breaker orientation matches the intended cut direction.
