Walter 5615013 Turning Insert Ccmt 80 Diamond WSM20

Product Description

The WALTER 5615013 is a solid carbide turning insert in the CCMT series, designed for precision finishing operations on CNC lathes and turning centers. It features an 80-degree diamond (rhombic) insert shape with a 0.0157 inch corner radius and a 1/4 inch inscribed circle diameter. The WSM20 grade substrate carries a multilayer PVD coating of TiAlN, Al2O3, and ZrCN, providing heat and wear resistance suited to demanding workpiece materials. With two cutting edges, a positive rake angle, and a honed cutting edge style, this insert is optimized for tight-tolerance finishing passes. Licensed machinists and CNC operators handling stainless steel and exotic alloy turning applications will recognize the CCMT-PF4 chip breaker geometry as a proven configuration for light-to-moderate depths of cut.

This insert is intended for turning, facing, and boring operations on stainless steel, superalloys, and titanium as primary workpiece materials, with steel as a secondary application. It is rated for Material Grades M20, P20, and S20, making it suitable for a broad range of production and job-shop environments. Maximum depth of cut is 0.0846 inches, and the length range for application is 0.0000 to 0.3000 inches. The PF4 chip breaker geometry promotes controlled chip evacuation during finishing cuts, reducing built-up edge risk on gummy or work-hardening materials.

Key Features

• 80-degree diamond (rhombic) insert shape with positive side clearance for reduced cutting forces
• Multilayer PVD coating: TiAlN, Al2O3, ZrCN for thermal and abrasion resistance
• PF4 chip breaker optimized for finishing operations with controlled chip flow
• Two usable cutting edges with neutral insert hand for flexible toolholder compatibility
• Honed cutting edge style minimizes edge chipping on stainless steel and superalloys
• Screw-held mounting method per CCMT toolholder standard

Compatibility

Designed for use in CCMT-compatible screw-clamp toolholders. ANSI Insert Code CCMT21.51 and ISO Insert Code CCMT060204. Suitable for turning, facing, and boring operations where M20, P20, or S20 grade tooling is specified.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians following standard CCMT screw-clamp insert seating procedures. Ensure the toolholder pocket and clamping screw are clean and free of chips before seating the insert. Power down and lock out the machine spindle before changing inserts. Do not exceed the published maximum depth of cut for this insert geometry, as overloading a finishing insert can cause premature edge failure or insert fracture.
