5/16" High-Performance TiALN Square Carbide End Mill

This Canadian-made high-performance carbide end mill features a 5/16" cutting diameter, four-flute square-end geometry and a 4" overall length for reaching recessed or difficult-to-access features. Its TiALN coating provides increased abrasion and heat resistance for dependable performance in demanding machining applications.

Variable-Pitch Performance with Extended Reach

A special helix design and variable flute pitch help reduce chatter, promote stable cutting and improve surface quality. The four-flute configuration provides a strong balance of cutting-edge strength and material removal, while the extended 4" overall length offers additional reach for deeper profiles, pockets and other restricted areas.
