Product Details

The bright finish on these end mills provides a smooth, polished surface. General purpose 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 high-speed steel ball end mills create a finer finish on the workpiece than roughing high-speed steel ball end mills. High-speed steel ball end mills offer good wear resistance for general purpose milling applications. They're more flexible and can absorb more shock and vibration than carbide, powdered-metal, or cobalt steel end mills. Also known as ball-nose end mills, ball end mills have a rounded nose and create a round-bottomed groove in milling tasks. They are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners.
