The carbide construction offers long tool life and durability, maintaining performance through demanding, high-speed machining sessions.
- Efficient chip evacuation with 4-flute design: The extra flutes help move chips away from the cut, reducing clogging and enabling smoother, quicker milling.
- Ball Nose geometry for precise contouring: The rounded tip follows complex curves and maintains consistent contact for accurate profiles and high-quality finishes.
- Durable carbide for long tool life: Hardened carbide provides rigidity and wear resistance for dependable performance in graphite, even at higher speeds.
This end mill delivers reliable, repeatable results, helping you speed up workflows, reduce downtime, and achieve clean edges and accurate details on graphite parts—from intricate contours to precise pocketing. Ideal for production runs and detailed prototyping alike, it combines precision with durability to support consistent performance across demanding projects.
