Description
The OSG Carbide 4 Flute End Mill is a precision cutting tool engineered for plastic and graphite machining. With a 10 mm diameter and a regular-length body, this end mill features a square-edge profile and four flutes to deliver fast, stable material removal and accurate dimensions.
Coated with diamond, the tool delivers exceptional wear resistance and longer service life in demanding jobs, reducing downtime and tool changes while maintaining consistent, high-quality finishes across plastic and graphite workpieces.
- Diamond Coating for Extended Tool Life: The diamond coating dramatically boosts wear resistance, helping the tool last longer in plastics and graphite and reducing the frequency of replacements during demanding runs.
- Four-Flute Design for Fast, Stable Cutting: Four flutes provide efficient material removal with strong rigidity, supporting quicker cycles and smoother finishes even on tougher plastics and graphite.
- Square-Edge Precision for Clean, Accurate Results: The square-edge geometry delivers precise shoulders and tight tolerances, yielding reliable, repeatable cuts in delicate plastic and graphite applications.
This end mill helps you complete projects faster with fewer interruptions, delivering repeatable results and tight tolerances in plastic and graphite parts. The durable diamond coating, rigid carbide body, and optimized flute geometry work together to improve surface quality, reduce chatter, and extend productive tool-life, making it a dependable choice for workshops, job shops, and production environments.
