Proper application of tolerances While tolerances are important, it is just as important to apply them correctly. One of the most important considerations when applying tolerances is fit. This is how shafts will fit into bearings or bushings, motors into pilot holes, and so on. Depending on your application, you might want a clearance fit to allow for expansion due to heat, a sliding fit for

Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations. The tooth design allows for little to no vibration, but
