Description
The OSG Carbide 3 Flute End Mill with Corner Radius is a versatile carbide cutting tool designed for general machining tasks. With a 5 mm diameter and a corner radius of R1.25, it features a regular-length, center-cutting design that handles milling, slotting, and profiling with ease across a range of materials.
The TiAlN coating boosts wear resistance and thermal stability, helping the tool maintain sharpness longer in demanding operations. The corner radius enhances cutting stability, delivering smoother cuts and better surface finishes while reducing chatter for more consistent results.
- Corner Radius for Smoother, Cleaner Finishes: The R1.25 corner radius softens entry and helps produce smoother contours with fewer tool marks, improving surface quality on complex profiles.
- TiAlN Coating for Extended Life: The titanium aluminum nitride coating provides enhanced wear resistance and heat tolerance, increasing tool life in challenging materials and higher-speed scenarios.
- Three-Flute, Center-Cutting Design for Versatility: The 3-flute geometry delivers efficient material removal and solid rigidity, while the center-cutting capability enables plunging and versatile milling in a single tool.
Designed for dependable, general-purpose performance, this end mill supports consistent results, smoother finishes, and longer tool life in everyday milling tasks. Its robust carbide construction, coating, and geometry help streamline workflows, reduce downtime, and deliver reliable outcomes across a wide range of applications for engineers, machinists, and hobbyists alike.
