Peculiarities
DeWalt drills are made of extra strong and high quality steels, which allows them to drill holes in other metals, stones, concrete and wood.
The design of the drills is specially developed by the company's specialists to solve certain technological problems and taking into account the characteristics of the material for which they will be used.
The main differences between drills are their appearance (length and diameter), purpose (according to the material in which the holes will be made) and the method of sharpening the cutting part.
An important feature is the strength of the products; they must be harder than the material to be drilled. There is also a small specific point - the type of shank. It can be cylindrical, polyhedral and conical. There is also a special type of shank designed to work with rock drills called SDS.
