Description
The OSG Carbide 3 Flute End Mill with Corner Radius is a versatile cutting tool designed for general machining tasks. With a 16 mm diameter, 2 mm corner radius, TiAlN coating, and regular-length center-cutting design, it's ideal for milling, slotting, and profiling across a wide range of materials.
- Three-Flute Design for Efficient Material Removal: The three-flute geometry provides a balance between aggressive chip evacuation and stable cutting, delivering fast material removal with smooth operation and good surface quality on a variety of materials.
- TiAlN Coating for Enhanced Wear Life: TiAlN boosts hardness and heat resistance at the cutting edge, extending tool life and maintaining sharpness during demanding operations and higher-temperature cutting.
- Corner Radius for Smoother Cuts and Finish: The 2 mm corner radius reduces edge chipping and improves surface finish, enabling cleaner profiles and slots with fewer passes.
This end mill supports efficient workflows by delivering reliable, consistent results across common general machining tasks. Its combination of robust carbide construction, protective TiAlN coating, and a practical corner radius helps you achieve better finishes, reduce downtime, and maintain accuracy throughout your project.
