What is a drilling operation?
Drilling involves using a drill to shape the material into predetermined dimensions. Drills are used to drill holes in metal, wood, plastic and similar materials. Depending on the drill used, it is possible to make holes in extremely hard materials, often to considerable depths. The exact size of the hole can be changed simply by changing the drill bit. Most machine shops that offer drilling services can offer a variety of options for different hole locations, shapes and sizes. Drilling speed is affected by the type of material being machined, the size of the drilled hole, and the efficiency of the cooling process. Modern machines benefit from advanced cooling systems for fast and accurate production.
