A drill chuck is a specialised self-centering, three-jaw chuck, usually with capacity of 0.5 in (13 mm) or less, and rarely greater than 1 in (25 mm), used to hold drill bits or other rotary tools. This type of chuck is used on tools ranging from professional equipment to inexpensive hand and power drills for domestic use.
From top: Spade, brad point, masonry, and twist drills bits Drill bit (upper left), mounted on a pistol-grip electric drill A set of masonry drills. A drill bit is a cutting tool used in a drill to remove material to create holes, almost always of circular cross-section. Drill bits come in many sizes and shapes and can create different kinds of ...
In April 2016, the Vuohensilta couple opened a secondary YouTube channel called Beyond the Press, featuring behind-the-scenes material from the Hydraulic Press Channel. The video content includes, for example, the usual work in the workshop, experimental videos as well as various creative ways to explode or destroy stuff beyond the hydraulic press.
Benchtop drill press (left) and floor-standing drill press (right) A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand ...
Large drill bits can have straight shanks narrower than the drill diameter so that they can be fitted in chucks not able to chuck the full diameter. Such a drill bit is called a reduced-shank or blacksmith's drill. For example, this allows a 1 ⁄ 2-inch (13 mm) bit to be used in a pistol-grip drill's 3 ⁄ 8-inch (9.5 mm) chuck.
Radial arm drill press. A radial arm drill press is a large geared-head drill press in which the head can be moved along an arm that radiates from the machine's column. As it is possible to swing the arm relative to the machine's base, a radial arm drill press is able to operate over a large area without having to reposition the workpiece.
Fast hole drilling EDM was designed for producing fast, accurate, small, deep holes. It is conceptually akin to sinker EDM but the electrode is a rotating tube conveying a pressurized jet of dielectric fluid. It can make a hole an inch deep in about a minute and is a good way to machine holes in materials too hard for twist-drill machining.
