Tapping heads are used with taps to produce threads in a workpiece. They are designed with a reversible spindle that allows the tap to back out of the hole when depth is reached, and may also include a clutch for limiting the torque which helps to prevent tap breakage. Tapping heads are attached to drilling, milling or tapping machines.

Aug 17, 2015· Thread milling is easier on the machine tool because it requires lower cutting forces than tapping. Because thread milling uses helical interpolation, it isn’t necessary to have the hole right on size because the thread mill will cut the hole larger. When operators tap, they drill the hole larger than necessary because it is easier.

Using Tap Guides . Tap guides are an integral part in making a usable and straight tap. When using the lathe or the mill, the tap is already straight and centered. When manually aligning a tap, be careful, as a 90° tap guide is much more accurate than the human eye. Using Oil . When drilling and tapping, it is crucial to use oil.
