A cutting tool is any tool that is used to remove material from the work-piece by means of shear deformation. Cutting tools must be made of a material harder than the material which is to be cut, and the tool must be able to withstand the heat generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the work-piece without the rest of the tool dragging on the work-piece surface. Cutting tools are made using a variety of materials and the selection of a cutting tool material depends on a variety of factors, like hardness and toughness.

Gear cutters are the cutters that are used to provide the shapes to the gears. The main function of gear cutters is to remove the material from the machine by their movement within the machine. A Gear shaper cutter is a gear cutter that has teeth, which is relieved for providing appropriate cutting edges and clearances. Shaving cutters are the gear cutters used to impart a shaving finish to the instruments and have numerous cutting teeth on their periphery, to perform the function.

Spline ...
... Broach is an instrument for cutting and sizing. They are usually made for only one user and for only a particular machining operation. Spline Broaches are utilized for manufacturing purpose to form holes or cut the surfaces. A variety of spline broaches available according to the specific work to be taken from them. The involute spline broach is used where the sides are equally spaced grooved are involute but are of short length. A straight sided spline broach is one, a push or pulls type broach, is used to produce a straight spline profile in the periphery of a prebore. A helical spline broach is one in which the teeth are grounded in a helical path around the tool axis.

Special cutters are the cutters specially designed to perform some specific tasks. Special cutters are unique and can perform one set of functions over the fix set of machinery. Some special cutters are like, shapers cutters, spline hobs, worm wheel hobs etc.
