Description
The Widin Carbide Corner Radius End Mill for Graphite (WGR502) is a precision cutting tool designed for machinists working with graphite components. With a 5 mm diameter, 40 mm overall length, and a 0.3 mm corner radius, it delivers clean, accurate cuts tailored to graphite applications.
- Diameter: 5 mm for precise material removal and control in graphite pockets and slots.
- Overall length: 40 mm to reach deeper pockets while maintaining rigidity and balance.
- Corner radius: R0.3 to produce smooth internal corners and improved edge life.
- Flutes: 2-flute neck type for efficient chip evacuation and steady cutting action.
- Material: Carbide construction offers high wear resistance and long tool life in graphite environments.
- Neck type: Necked design increases stability and reduces deflection during deep cuts.
- Application focus: Specifically engineered for graphite machining to enhance finish, accuracy, and reliability.
This end mill is ideal for engineers and CNC operators aiming for consistent finishes on graphite components, such as electrical interfaces, thermal management parts, and graphite electrodes. The combination of a two-flute neck geometry, carbide durability, and a tight corner radius helps minimize chipping, manage heat, and extend tool life, even under repetitive machining cycles. Use it to achieve precise profiles, smooth corners, and reliable performance in graphite milling projects.
