Use Cutting Tools For Precision Metalworking

Defined Tag: Cutting Tools.
When most people hear the phrase cutting tools, they think of scissors, knives, and saws. Those are certainly tools that cut. That is true for everyone except metalworkers, however. In metalworking, a cutting tool is a specialized tool used to mill, machine, or shape metal parts. These cutting implements are often specialized drill bits that turn at high rates of speed to cut away the metal.
A cutting tool works on metal much as a woodworker uses a router to shape the edge of a board by cutting away material with the routing bit. In the case of a cutting tool, however, the process creates metal shavings rather than wood chips. There are three important characteristics to metal cutting bits and tools.
The first necessary property of tools used for metal cutting is that they must move very fast. A drill must spin quickly to make holes in wood. The metal cutting bit must also spin very quickly in order to remove the desired amount of metal. Metal is much harder than wood, so the cutting tool must be strong too. Spinning the cutting bit very rapidly creates more shear force through which the tool removes the metal.
Next, tools used for metal cutting must be harder than what they are cutting. That seems rather obvious, but it is essential. If you try to cut a metal bar with a saw meant for wood, all you will do is wear down the saw teeth. In effect, the metal bar would be cutting the saw! If the metal to be cut is extremely hard, the cutting tool can be artificially hardened by adding coatings of carbide or even industrial diamonds.
Finally, metal cutting tools must be kept cool during the machining process. As you might imagine, metal on metal friction creates a great deal of heat. This heat is intense enough to melt the cutting tool, the metal object, or both, especially at high cutting speeds. Special cutting oils and lubricants are sprayed onto the cutting bit as it works, reducing the temperature and also removing metal shavings.
Unless you are a metalworker, you will likely not need a specialized cutting tool to machine metal parts. These hardworking cutting bits shape many of the metal items you use each day. Cutting tools will give precision cuts as long as they are appropriate to the metal being cut, used at the correct cutting speed, and are cooled as they work.
