Walter-prototyp 6814326 Corner Radius End Mill 4 Flute 8mm

Product Description

The WALTER-PROTOTYP 6814326 is a solid carbide corner radius end mill head engineered for high-performance milling in demanding materials. Carrying a TiAlN PVD coating under the WK40RC material grade designation, this single-end tool delivers both roughing and finishing capability in one geometry. The 4-flute configuration features a variable helix and right-hand cutting direction to reduce chatter and improve chip evacuation. With an 8.00mm mill diameter and a 0.50mm corner radius, it is built for precise contouring and edge integrity in production environments. Machinists and tooling technicians working with CNC machining centers are the primary installers of this head.

This end mill head is designed for stainless steel as its primary workpiece material, with secondary suitability for superalloys and titanium. The extended reach geometry, with a 27.00mm reach length and 19.00mm length of cut, makes it well suited for deep-pocket milling and long-reach applications where a standard-length tool cannot access the feature. The straight-cylindrical shank with an 8.00mm diameter and h5 tolerance is compatible with precision toolholders used in CNC milling operations. The normal pitch and center-cutting capability round out its application range for both slotting and peripheral milling passes.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN PVD coating (WK40RC grade) for elevated heat resistance and extended tool life
• Variable helix flute geometry reduces vibration and improves surface finish
• Extended reach design with 27.00mm reach length for deep-pocket and long-reach applications
• Center-cutting capable, supporting both plunge entry and peripheral milling
• Roughing and finishing material removal in a single tool for stainless steel and superalloys

Compatibility

Designed for use with precision CNC toolholders accepting an 8.00mm straight-cylindrical shank. Catalog reference MC251-08.0-A4B100, Series MC251.

Installation Notes

Installation is performed by a qualified machinist or tooling technician on a CNC milling machine. Ensure the toolholder bore and retention mechanism are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping before initiating a cut. Always reference the manufacturer cutting data recommendations for feed rate, spindle speed, and depth of cut specific to the workpiece material and machine capability.
