Walter-prototyp 6814324 Corner Radius End Mill 6mm 4 Flute

Product Description

The WALTER-PROTOTYP 6814324 is a solid carbide corner radius end mill head engineered for demanding metal removal applications in stainless steel, superalloys, and titanium. Part of the MC251 series, it carries a TiAlN (PVD) coating under the proprietary WK40RC material grade designation. The 6mm mill diameter pairs with a 0.50mm corner radius to reduce chipping at the cutting edge during both roughing and finishing passes. With a variable helix flute geometry and extended reach design, this single-end head is built for situations where tool rigidity and chip evacuation are both critical. It mounts to compatible straight-cylindrical toolholders and is manufactured to h9 mill diameter and h5 shank diameter tolerances.

This end mill head is suited for machining stainless steel and high-temperature alloys in precision manufacturing environments. The extended reach and 13mm length of cut make it applicable in pocketing, contouring, and profiling operations where clearance is limited. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. It is intended for use with compatible toolholders and is appropriate for shops running aerospace, medical, or industrial component work where tight tolerances and difficult materials are routine.

Key Features

• Solid carbide construction with TiAlN PVD coating (WK40RC grade) for heat and wear resistance in hard materials
• Variable helix flute geometry promotes chip evacuation and reduces chatter during cut
• 0.50mm (0.0390 inch) corner radius reduces edge chipping on stainless steel and superalloy workpieces
• Extended reach design with 21mm reach length for clearance in deep-pocket applications
• Center-cutting capable, supporting plunge and ramp entry moves
• Right-hand cut, right-hand flute, single end configuration for standard CNC milling spindles

Compatibility

Designed for use with straight-cylindrical toolholders compatible with a 6mm shank diameter. Catalog reference MC251-06.0-A4B100. Primary workpiece materials are stainless steel (ISO material code M) and superalloys and titanium (ISO material code S).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's clamping specifications. Ensure the toolholder collet or chuck bore is clean and free of debris before seating the shank. Confirm runout is within acceptable limits using a dial indicator before beginning the cut. Do not exceed the rated reach depth without verifying adequate tool rigidity for the workpiece material.
