Roughing end mills feature nicks or serrations along the cutting edge which act as mechanical chip breakers to produce shorter, more manageable chips. Typically used in “roughing” applications where deep depths of cut and low horsepower machine capability are present.
Ball nose end mills, featuring a full radius, are ideally suited for milling 3-D contoured parts. The full radius, or ball shape, permits high accuracy contouring and profiling while minimizing corner chipping more prevalent with square and corner radius end mills.
Double Ended mills feature end mill geometry on both ends of the tool, allowing an operator to rotate the tool once before discarding due to wear. Double ended mills are typically available in square, corner radius, and ball nose configurations.
