You can feed it by hand or feed it automatically. If you choose to feed it automatically, it has an automatic table-raising mechanism that helps the machine work by itself and helps move the surface around the drill. Upright Drilling Machines are used for larger holes and for bigger projects. Aside from these machines, one of the more commonly used is called the radial-arm drilling machine machine. This machine is very versatile and convenient drill that can be used, due to its accessible design. It can be moved around the work area, allowing it to be used in larger-scaled projects and can be used with a tilting table to create holes that are angular or intersect. These are some of the basic types of drills that exist. Along with these, there exist of special-purpose drills that are more intricate than the ones mentioned before. One of these machines is called the multiple spindle drill machine, which holds multiple heads to complete its task. Typically, this type of drill uses four heads.
The first can be used to determine where to drill the hole. The second and third one can be used to tap the hole, and the fourth drills the actual hole. Another drill that uses multiple heads is a Multi-Spindle Drill Press. It has many spindles connect to one main piece and is hand-fed. This machine is ideal for when there are many pieces that need to be worked on and have multiple holes close to each other. A micro drill press can make tiny holes, hence the name.
