The Widin Carbide Corner Radius End Mill for Graphite (WGR502) is a purpose-built cutting tool designed for precise graphite machining. Its 3 mm diameter, 20 mm overall length, and R0.2 corner radius deliver clean, dimensional cuts with reliable stability in compact workspaces.

• Diameter: 3 mm
• Overall length: 20 mm
• Flutes: 2 flutes
• Neck-type design: Increased rigidity and reduced deflection for stable cutting in graphite
• Corner radius: R0.2 mm for smoother entry/exit and improved edge quality
• Material: Solid carbide for exceptional wear resistance and long tool life
• Application: Specifically optimized for graphite machining to minimize fraying and chipping

Designed to tackle graphite’s unique properties—high thermal conductivity and low friction—this end mill maintains sharpness through multiple passes and delivers consistent results across electrodes, molds, and other graphite components. The neck-style geometry supports deeper engagement with minimal tool deflection, while the two-flute configuration facilitates efficient chip evacuation in the fibrous graphite structure, helping you maintain smooth finishes and accurate dimensions.
