A cutting tool is one of many types of tool that remove substantial amounts material, in a controlled manner, from the material being worked. They can be operated by muscle strength or by a mechanical motor.
Saws remove material primarily through abrasion, and cut partially or fully through materials. Drills bore holes in material.
A finishing tool such as a sander (tool) or plane (tool) also removes material, but for smoothing rather than making multiple pieces or making major changes in the shape of the work.
