The Drill, also called wick, is a piece of cutting metal, which is always used linked to a mechanical tool called a drill or any other related machine. The latter is the one that rotates the drill bit and its main use is for make holes or holes in different materials.
Mostly, it is the industries that use the drill, while it is common for each industry to adapt the drill to its particular use, therefore, there is a wide variety of drills on the market.
Meanwhile, the design of the drills must consider the material that must be removed, that is, for example, the hardness that it presents in order to define the speed and the shape that best suits the material on which it will work.
It should be noted that the edge of the drill becomes dull with recurrent use, therefore, it is essential, to contribute to its care, to sharpen it from time to time and thus recover its initial cutting capacity.
There are several ways to sharpen a drill, through sharpening machines, this type is the most common in machining industries, although it is also possible to sharpen them by hand using small grinders that have fine-grained wheels; This type of manual sharpening requires, of course, a special skill to carry it out so as not to make mistakes when it comes to achieving the best cutting angle.
Among the most common types of drill bits, the following stand out: Long drill (It is used especially for those places where the normal drill does not reach, such is the case when you have to make a hole inside a piece of equipment or part), Super long bit (used at the instance of the need to drill walls to pass cables), center drill (specially designed to make centering points of an axis and thus facilitate turning), paddle bit (designed for use on wood), deep hole or shotgun bit, drill bit for digging (used in the drilling of oil wells) and normal twist drill.
On the other hand, the term drill is used in common language to refer to a typical parasitic insect of coffee.
