Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these types of cutting tools are often made from HSS (High-Speed-Steel).
Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [ 2 ] on one or several axes, cutter head speed, and pressure. [ 3 ]
A metalworking shaper is somewhat analogous to a metalworking planer, with the cutter riding a ram that moves relative to a stationary workpiece, rather than the workpiece moving beneath the cutter. The ram is typically actuated by a mechanical crank inside the column, though hydraulically actuated shapers are increasingly used.
Cutter forces are high, so milling machines must be robust and rigid, usually substantial constructions of cast iron. Intermediate materials, such as plastics and sometimes soft aluminium, may be cut by either method, though routing aluminium is usually more of an improvised expedient than a production process, and is noisy and hard on tools.
In rotary broaching, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape. A rotary broach is used in a lathe or screw machine. In both processes the cut is performed in one pass of the broach, which makes it very efficient. Broaching is used when precision machining is required, especially for odd shapes.

A rotary cutter is a tool generally used by quilters to cut fabric.It consists of a handle with a circular blade that rotates, thus the tool's name. Rotary cutter blades are very sharp, can be resharpened, and are available in different sizes: usually smaller blades are used to cut small curves, while larger blades are used to cut to straight lines and broad curves.
