Walter 5197925 Dcgt Turning Insert 55 Diamond Carbide

Product Description

The WALTER 5197925 is a solid carbide turning insert in a 55-degree diamond (DCGT) shape, finished with a TiCN Plus PVD coating and a PF2 chip breaker geometry. It carries ANSI insert code DCGT32.51 and ISO code DCGT11T304-PF2 WXN10. The insert measures 11.63 mm (0.458 inches) in length with a 3/8-inch inscribed circle and a 1/64-inch (0.0157-inch) corner radius. The WXN10 grade, combined with an 18-degree positive rake angle and honed cutting edge, is engineered for clean, controlled chip formation in precision turning applications. It is installed by machinists and CNC turning specialists in production and job-shop environments.

This insert is designed primarily for non-ferrous metal machining, with secondary capability on steel and stainless steel. The PF2 chip breaker geometry supports turning, facing, boring, and back turning operations. With a maximum depth of cut of 2.49 mm (0.098 inches) and a positive side clearance, it is well suited for light to moderate finishing cuts where dimensional accuracy and surface finish are priorities. The neutral insert hand provides flexibility across a range of toolholder orientations.

Key Features

• 55-degree diamond (DCGT) insert shape with 7-degree relief angle and positive rake geometry
• TiCN Plus PVD coating on carbide substrate for wear resistance on non-ferrous and steel workpieces
• PF2 chip breaker supports turning, facing, boring, and back turning operations
• Honed cutting edge and 1/64-inch corner radius for controlled finishing cuts
• 2 cutting edges per insert; screw-mounted insert holding method
• Meets ANSI and ISO standards; material grades M01, N10, and P01

Compatibility

Designed as an OEM-style replacement or direct-use insert for DCGT-style toolholders conforming to ANSI and ISO standards for 55-degree diamond inserts with a 3/8-inch inscribed circle and screw-clamp holding systems.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid cracking the carbide substrate - do not overtighten by hand or with standard hex keys beyond the toolholder manufacturer's specification. Inspect the seating pocket for chips or debris before installing a fresh edge.
