A cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation. The majority of these tools are designed exclusively for metals.
Metal cutting tools have a primary purpose of removing leftover material from a manufactured piece of metal by using the process of shear deformation. There are mainly two types of metal cutting tools that are normally used; single point tools and multi-point tools.
