Walter 7376602 Turning Insert DNMG432-MM5 WMP20S Carbide

Product Description

The WALTER 7376602 is a solid carbide turning insert in the DNMG432-MM5 series, grade WMP20S, designed for high-performance metal cutting on CNC lathes and turning centers. The insert features a triple-layer CVD coating of TiCN, Al2O3, and TiCN, delivering wear resistance and thermal stability across a range of workpiece materials. It carries a 55-degree diamond shape (D), a neutral hand orientation, and an MM5 chip breaker geometry. With a 0.5000-inch inscribed circle, 0.6104-inch length, and a 0.0315-inch corner radius, this insert is suited for moderate to aggressive material removal in production turning environments. Licensed machinists and CNC operators are the primary users.

This insert is intended for turning, facing, boring, and back turning operations in ISO material groups P (steel), M (stainless steel), and S (super-alloys and titanium), corresponding to material grades P25, M20, and S20. The MM5 chip breaker geometry is optimized for medium-depth interrupted and continuous cuts in these material families. It conforms to both ANSI and ISO standards, with an ISO designation of DNMG150408-MM5 WMP20S. The insert is held by clamp and pin, compatible with standard DNMG-style toolholders used in production and job-shop turning applications.

Key Features

• MM5 chip breaker geometry optimized for turning, facing, boring, and back turning
• 55-degree diamond insert shape with 4 cutting edges for maximum indexing value
• Neutral hand orientation compatible with standard DNMG right- and left-hand toolholders
• Chamfered and honed cutting edge style for balanced edge strength and surface finish
• Conforms to ANSI and ISO standards; dual-certified for interchangeability

Compatibility

Designed for use in standard DNMG-style toolholders accepting a 0.5000-inch inscribed circle, 55-degree diamond insert with clamp and pin holding method, per ANSI and ISO DNMG432 specifications.

Installation Notes

Installation is performed by licensed CNC machinists or toolroom technicians. The machine spindle must be stopped and all axis motion locked before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified fastener for the toolholder clamp to ensure proper seating. Inspect the toolholder pocket and seating surface for chips or wear before installing a new insert.
