Morse tapers refer to a a series of shanks that taper at the end so they can be mounted onto the spindle of a drill press or lathe. They can be quickly removed during an operation. The taper is approcimatly 5/8 inches per foot.

Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.
