Description
The Widin Carbide End Mill for Graphite (WGB504) is a precision cutting tool designed specifically for graphite machining. With a 1 mm diameter and a 20 mm length of cut, its 4-flute, ball-nose geometry is optimized for accurate contouring and efficient material removal in tight graphite features.
Graphite's high thermal conductivity and low friction can challenge tools, but this end mill's carbide construction is built for durability and long tool life. A 4-flute design improves chip evacuation, helping prevent clogging and delivering smoother cuts on complex shapes.
- Ball-nose geometry for precise contouring: The rounded tip follows complex graphite shapes with high accuracy, producing smooth profiles and detailed finishes.
- 4-flute design for efficient chip evacuation: More flutes help evacuate graphite chips quickly, reducing heat buildup and preventing clogging for cleaner cuts on intricate features.
- Solid carbide construction for long tool life: Hardened carbide delivers wear resistance and reliability at high speeds, reducing tool changes and downtime.
Designed for engineers, machinists, hobbyists, and production teams, the Widin WGB504 helps you achieve repeatable, high-quality graphite contours with less downtime. Its compact 1 mm diameter and 20 mm LOC are ideal for tight pockets and fine-detail work, while the ball-nose profile and four flutes deliver accurate profiles, smooth finishes, and dependable performance across demanding graphite applications.
