The Widin Carbide Corner Radius End Mill for Graphite (WGR504) is a precision cutting tool built for engineers and shops that routinely machine graphite components. With a 4-flute design, a 4 mm diameter, and a 100 mm overall length, it delivers clean, accurate cuts and reliable tool life.

• Diameter: 4 mm
• Overall length: 100 mm
• Corner radius: R1.0 (1.0 mm)
• Flute count: 4-flute design for efficient chip evacuation
• Material: Solid carbide for hardness, toughness, and heat resistance
• Application: Specifically optimized for graphite machining
• Chip evacuation: Geometry designed to move chips away from the cutting edge quickly

Designed to tackle graphite’s unique properties—high thermal and electrical conductivity and self-lubricating behavior—this end mill maintains rigidity and reduces wear during demanding milling. The corner radius enhances edge strength, helping resist chipping and extending tool life, while the 4-flute configuration supports steady cutting and efficient material removal. For production-grade or precision prototyping, the WGR504 delivers dependable performance on graphite parts with consistent surface finishes.
