Cold saw. A cold saw is a circular saw designed to cut metal which uses a toothed blade to transfer the heat generated by cutting to the chips created by the saw blade, allowing both the blade and material being cut to remain cool. [1] This is in contrast to an abrasive saw, which abrades the metal and generates a great deal of heat absorbed by ...
In the context of machining, a cutting toolor cutteris typically a hardened metal toolthat is used to cut, shape, and remove material from a workpieceby means of machining toolsas well as abrasive toolsby way of shear deformation. The majority of these tools are designed exclusively for metals. There are several different types of single-edge ...
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws . Saws began as serrated materials, and when mankind learned how to use iron, it became the preferred material for saw blades of all kind.
An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder.

A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking, metalworking, and ...
The most common blade materials are carbon steel, stainless steel, tool steel, and alloy steel. Less common materials in blades include cobalt and titanium alloys, ceramic, obsidian, and plastic . The hardness of steel is usually stated as a number on the Rockwell C scale (HRC). The Rockwell scale is a hardness scale based on the resistance to ...
