Description
The OSG Carbide 3 Flute End Mill is a 20 mm diameter tool with a 0.25 mm corner radius and a Diamond-Like Carbon (DLC) coating, engineered for precision aluminium machining. Featuring three flutes, it delivers stable, efficient material removal and consistent profiles.
The DLC coating extends tool life and enhances wear resistance, making it well-suited for demanding aluminium operations where reliable performance matters.
- Three-flute design for fast, stable aluminium cutting: With a 20 mm diameter and three cutting edges, this end mill delivers efficient material removal and smooth chip evacuation for consistent finishes.
- DLC coating for extended tool life and wear resistance: Diamond-Like Carbon coating reduces friction and protects cutting edges, helping the tool last longer in aluminium machining and resist wear during high-speed operations.
- Corner radius of R0.25 for precise radii and edge strength: The 0.25 mm corner radius enables accurate radii in aluminium parts and reduces edge chipping, delivering reliable corner finishes and increased part integrity.
Designed for aluminium machining, this end mill helps you achieve reliable, repeatable results with tight tolerances. The DLC coating reduces wear and extends tool life, meaning fewer tool changes and less downtime. With its stable 3-flute geometry and precise corner radius, you can expect smooth finishes and consistent dimensions across production runs.
