Description
Meet the OSG Carbide 2 Flute End Mill with Ball Nose—a regular-length, center-cutting milling tool built for general machining tasks. With a 3.5 mm diameter and a TiAlN coating, it delivers precise contouring and profiling across a wide range of materials, making it suitable for engineers, buyers, tradespeople, hobbyists, and production shops alike.
- Ball Nose geometry for smooth contouring: The rounded tip provides gentle, consistent cuts that help achieve smooth surfaces and accurate 3D profiles, even on complex curves.
- TiAlN coating for durability: High hardness and heat resistance extend tool life, reduce wear, and help you maintain productive runs in demanding materials.
- Regular-length, center-cutting design: Offers stability and plunging capability, enabling versatile entry and reliable performance across depths and a variety of machining tasks.
This end mill is designed to deliver dependable, repeatable results in everyday milling workflows. The carbide core and TiAlN coating work together to resist wear, while the two-flute configuration supports efficient material removal and steady feeds, helping you achieve consistent finishes and reduce downtime across general milling applications.
