ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. the design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. because of the shapes required in these products its common that multi axis machining
ball nose end mills are used on workpieces with complex surfaces. choosing flat end mill vs. a ball end mill will determine the characteristics of the tooling marks on your model. most jobs will benefit from strategic use of multiple size and shape tools for milling different features. end mills are often used for roughing and
the typical explanation is that the ball was measured thirty times and the size averaged. have also seen the reverse where almost perfect balls were measured with a large variability, but it was explained that it didnt matter because the final size was the average of a lot of measurements.
when one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. use them to round sharp corners on the edge of your workpiece.
