The Widin Carbide Corner Radius End Mill for Graphite (WGR502) is a precision cutting tool designed specifically for graphite workpieces. With a 3 mm diameter, 25 mm overall length, a 0.2 mm corner radius, and a 2-flute neck design, it delivers reliable, clean cuts tailored to graphite applications.

• Diameter: 3 mm
• Overall Length / Neck Type: 25 mm with a neck-style design for added stability and reduced deflection
• Corner Radius: R0.2 for smoother corners and lower edge chipping
• Flute Count: 2 flutes to balance rigidity and chip evacuation
• Material: Solid carbide for superior wear resistance and durability
• Primary Application: Optimized for graphite machining, delivering consistent performance on graphite electrodes, blocks, and precision components

The tool’s 2-flute neck design enhances rigidity and enables efficient chip evacuation, reducing heat build-up and the risk of tool breakage during graphite cutting. The carbide construction ensures long tool life even under continuous use, while the corner radius helps maintain clean edges and precise corner geometry—crucial for EDM electrodes and high-precision graphite parts. This end mill is ideal for engineers and machinists seeking stable, repeatable results in graphite machining projects, from rapid prototyping to production-level components.
