Learn more about Klarna
The OSG Carbide 2 Flute End Mill with Corner Radius is a general‑purpose cutting tool designed for milling, slotting and profiling. With an 8 mm diameter and a 2.5 mm corner radius, its two‑flute, center‑cutting design enables efficient, dependable cuts across a wide range of materials. TiAlN coating enhances wear resistance and heat tolerance, helping the tool stay sharp longer in demanding operations.
Suitable for engineers, machinists, shops and hobbyists alike, this end mill delivers consistent results, improved surface finishes, and predictable performance in everyday manufacturing and prototyping tasks.
- Corner Radius for Smoother, More Reliable Cuts: The R2.5 radius reduces edge chipping and produces smoother profiles, improving surface quality on a variety of materials and in tight corners or interrupted cuts.
- TiAlN Coating for Extended Life and Heat Resistance: The advanced coating reduces wear, lowers friction, and extends tool life when cutting hard or heat‑generating materials, helping you run longer between changes.
- Center‑Cutting 2‑Flute Design for Versatility: Center‑cutting capability allows plunging as well as milling, while the two flutes provide efficient material removal, stable cuts, and easy chip evacuation for general machining tasks.
This end mill supports reliable performance and consistent results across a broad range of jobs—from quick prototyping to routine production. The combination of carbide hardness, TiAlN coating, corner radius, and center‑cut geometry helps you achieve precise dimensions, smooth finishes, and reduced downtime, making it a dependable choice for daily machining needs.
