Sq. End Mill Single End HSS 1 MPN:C39745

Three-flute end mills clear chips more quickly than end mills with more flutes and allow for higher feed rates than end mills with fewer flutes. They also typically have larger cores and are less prone to breaking than end mills with fewer flutes.

General purpose high-speed steel square end mills are intended for milling a wide variety of common materials but are not suitable for milling hard materials like titanium or gummy materials like aluminum. Finishing end mills create a finer finish on the workpiece than roughing and roughing/finishing end mills. High-speed steel square end mills offer good wear resistance for basic milling applications. They're more flexible and can absorb more shock and vibration than carbide, cobalt, or powdered-metal end mills. These end mills have a bright finish that provides a smooth, polished surface. Sometimes called square-nose end mills, square end mills have a square nose and are rotated against a piece of stock to create a flat-bottomed groove with 90° inside corners in milling tasks. They are used for counterboring, side and face milling, and milling square shoulders.
