Description
The OSG Carbide 4 Flute End Mill with a Ball Nose, regular length, and TiAlN coating is a 10 mm diameter carbide milling tool designed for general machining tasks. Its ball-nose profile makes it ideal for contouring, profiling, and 3D work, delivering smooth radii and accurate surface finishes while four flutes balance material removal and finishing capability.
The TiAlN coating provides enhanced wear resistance to help extend tool life in demanding operations, so you can maintain productivity even under higher-speed conditions and tougher materials. With its regular-length design and center-cutting capability, this end mill offers reliable performance across a wide range of everyday machining applications.
- Ball Nose for Smooth Contouring: The rounded tip creates gentle radii on complex surfaces and 3D features, delivering consistent finishes on curved geometries.
- TiAlN Coating for Wear Resistance: The protective coating reduces wear and heat buildup, extending tool life and maintaining sharpness during challenging cuts.
- Center-Cutting, Regular-Length 4-Flute Design: Provides versatile plunge capability and stable cutting across a broad set of general applications, with ample rigidity for reliable, repeatable results.
This end mill helps you streamline production by delivering precise contours and smooth finishes quickly, reducing downtime through its durable carbide core and wear-resistant TiAlN coating. Its center-cutting design and four-flute geometry provide reliable performance across a broad set of general machining tasks, helping you achieve consistent results and maintain productivity in daily operations.
