Description
The OSG Carbide 3 Flute End Mill with a corner radius is a precision cutting tool designed for aluminum workpieces. Sized at 25 mm in diameter with a 3 mm corner radius, it delivers stable, accurate milling, profiling, and slotting performance across a wide range of projects—from production runs to DIY prototypes.
This end mill is ideal for engineers, machinists, hobbyists, and manufacturing professionals who need reliable results with aluminum parts. Its balanced geometry and robust carbide construction provide consistent performance, helping you achieve clean profiles and precise slots with fewer passes and less rework.
- Three-flute carbide design: Ensures efficient material removal and stable cutting with excellent chip evacuation, enabling faster cycles and smoother finishes on aluminum.
- Corner radius for edge strength and finish: Rounded corners reduce edge chipping and wear, delivering consistent profiles and longer tool life even when machining tight radii.
- Aluminum-optimized geometry: Engineered to minimize built-up edge and deliver clean cuts with fewer finishing passes, improving surface quality and overall productivity.
Designed for dependable performance from the first cut to the last, this end mill helps you streamline workflows, reduce downtime, and produce high-quality aluminum components with confidence. Its robust construction and thoughtful geometry make it a practical, long-lasting choice for both demanding production environments and precise, small-batch work.
