Description
The OSG Carbide 3 Flute End Mill with a corner radius and Diamond-Like Carbon (DLC) coating is a precision cutting tool designed for aluminum. It features a 16 mm diameter and a corner radius of 0.25 mm to deliver clean cuts with stable performance. It’s ideal for machinists, engineers, hobbyists, and shops that need reliable tooling for high-precision pocketing, profiling, and contouring in aluminum. The DLC coating enhances wear resistance, extending tool life even in demanding machining conditions.
- Three-Flute Geometry: Optimized for aluminum, this 3-flute setup boosts material removal while maintaining rigidity, helping you finish pockets and profiles faster with less chatter and better surface finish.
- Corner Radius R0.25: The precise 0.25 mm corner radius strengthens internal corners and delivers smooth, accurate radii on edges, reducing chipping and rework.
- DLC Coating for Longer Tool Life: The Diamond-Like Carbon coating hardens the surface, delivering improved wear resistance and longer tool life in aluminum machining, even under high-speed conditions.
Combined, this end mill helps you streamline aluminum workflows: faster, cleaner cuts; fewer tool changes thanks to extended life; and reliable, repeatable results you can trust for tight tolerances and smooth finishes. With a robust carbide body and DLC protection, you’ll experience consistent performance across jobs—from prototype runs to production milling—whether you’re pocketing, profiling, or contouring alloy parts.
