Walter 6353406 Turning Insert DNMG332-MK5 WKK10S Carbide

Product Description

The WALTER 6353406 is a DNMG-style solid carbide turning insert designed for precision material removal on CNC lathes and turning centers. Formatted to the DNMG332-MK5 WKK10S industry standard, this insert carries a triple-layer CVD coating of TiCN, Al2O3, and TiCN that delivers high wear resistance and thermal stability at the cutting edge. It features a 55-degree diamond shape, a negative rake angle of 14 degrees, and a chamfered and honed cutting edge style. With four usable cutting edges and an MK5 chip breaker geometry, it is suited for productive turning, facing, boring, and back turning operations performed by machinists and CNC tool-and-die technicians.

This insert is engineered primarily for cast iron workpieces and is also rated for hard materials. The MK5 chip breaker geometry controls chip flow effectively during medium to semi-finish passes. A maximum depth of cut of 0.1575 inches makes it appropriate for finishing and light roughing operations. It is held in place by clamp or pin-style toolholders and is compatible with standard DNMG insert seats found on most common turning tool bodies used in production and job-shop environments.

Key Features

• CVD triple-layer TiCN, Al2O3, TiCN coating for high wear resistance on cast iron and hard materials
• 55-degree diamond insert shape with negative rake geometry for stable, secure cutting
• MK5 chip breaker for controlled chip formation during medium and finish turning
• Four cutting edges per insert for extended tool life and lower cost per edge
• Chamfered and honed cutting edge style reduces chipping and improves edge integrity
• Suitable for turning, facing, boring, and back turning in a single insert style

Compatibility

Designed for use in standard DNMG insert toolholders that accept a clamp or pin holding method. ISO code DNMG110408-MK5 WKK10S and ANSI industry standard number DNMG332-MK5 WKK10S apply. Consult your toolholder documentation to confirm seat and clamp compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer when securing the clamping pin or screw. Inspect the insert seat and clamp for wear or debris before seating the new insert to ensure proper contact and edge positioning.
