5/16" High-Performance TiALN Ball Nose Carbide End Mill

This Canadian-made high-performance carbide end mill combines four-flute ball nose geometry with a 4" overall length for extended-reach contouring and profiling. Its TiALN coating provides increased abrasion and heat resistance for dependable performance in demanding machining applications.

Extended-Reach Contouring with Reduced Chatter

The ball nose cutting end is designed for machining curved surfaces, radii and detailed three-dimensional profiles. A special helix design and variable flute pitch help reduce chatter and promote stable cutting, while the four-flute configuration supports smooth finishes and consistent performance.
