Walter 6353300 CNMG433-MK5 Carbide Turning Insert

Product Description

The WALTER 6353300 is a CNMG-style indexable turning insert in the Tiger-tec Silver WKK10S grade, designed for precision metal cutting on CNC lathes and turning centers. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiCN over a solid carbide substrate, delivering high wear resistance and thermal stability at elevated cutting speeds. The 80-degree diamond insert shape provides a strong, rigid cutting geometry suited to heavy and interrupted cuts. With 4 cutting edges and a negative rake angle, this insert is built for productive, cost-efficient turning operations performed by machinists and toolroom professionals.

This insert is optimized for turning, facing, and boring operations with cast iron as the primary workpiece material, and is also rated for hard materials. The MK5 chip breaker geometry controls chip flow during moderate to heavy cuts. It is sized at 0.5 inch inscribed circle with a 0.0469 inch corner radius and holds to CNMG tolerances per ANSI and ISO standards, making it a direct fit in standard CNMG toolholders used in production and job-shop environments alike.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiCN for extended tool life on cast iron and hard materials
• WKK10S proprietary grade - ISO material grades H30 and K10
• MK5 chip breaker for controlled chip evacuation during turning, facing, and boring
• 4 indexable cutting edges per insert for reduced cost per edge
• Chamfered and honed cutting edge style for edge stability and reduced chipping
• Neutral hand orientation compatible with standard CNMG clamp and pin toolholders

Compatibility

Designed for use in standard CNMG clamp and pin style toolholders. ISO equivalent designation is CNMG120412-MK5 WKK10S. Compatible with turning, facing, and boring applications on cast iron and hard workpiece materials.

Installation Notes

Indexable inserts of this type are installed and indexed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification. Inspect the cutting edge and chip breaker geometry before resuming cuts to confirm correct seating.
