A drill is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck. Some powered drills also include a hammer function.
Drill bits are cutting tools used 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 holes in many different materials. In order to create holes drill bits are usually attached to a drill, which powers them to cut through the workpiece, typically by rotation. The drill will grasp the upper end of a bit called the shank in the chuck.
A military parade is a formation of soldiers whose movement is restricted by close-order manoeuvering known as drilling or marching. The military parade is now almost entirely ceremonial, though soldiers from time immemorial up until the late 19th century fought in formation. Massed parades may also hold a role for propaganda purposes, being used to exhibit the apparent military strength of one's nation.
Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the work-piece, cutting off chips (swarf) from the hole as it is drilled.
The hurry-up offense is an American football offensive style, which has two different but related forms in which the offensive team avoids delays between plays. The hurry-up, no-huddle offense (HUNH) refers to avoiding or shortening the huddle to limit or disrupt defensive strategies and flexibility. The two-minute drill is a clock-management strategy that may limit huddles but also emphasizes plays that stop the game clock. While the two-minute drill refers to parts of the game with little time remaining on the game clock, the no-huddle may be used in some form at any time. The no-huddle offense was pioneered by the Cincinnati Bengals and reached its most famous and complete usage by the Buffalo Bills, nicknamed the "K-Gun", during the 1990s under head coach Marv Levy and offensive coordinator Ted Marchibroda.
A hammer drill, also known as a percussion drill or impact drill, is a power tool used chiefly for drilling in hard materials. It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screwdriving.
The United States Marine Corps Silent Drill Platoon is a 24-man rifle platoon of the United States Marine Corps. Often referred to as The Marching Twenty-Four, the unit performs a unique silent precision exhibition drill. The purpose of the platoon is to exemplify the discipline and professionalism of the Marine Corps.
A brace is a hand tool used with a bit to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. Bits used come in a variety of types but the more commonly used Ridgeway- and Irwin- pattern bits also rely on a snail point, which is a tapered screw point shaped the same as a wood screw thread, which helps to pull the bit into the wood as the user turns the brace handle and applies pressure
Mud logging is the creation of a detailed record of a borehole by examining the cuttings of rock brought to the surface by the circulating drilling medium. Mud logging is usually performed by a third-party mud logging company. This provides well owners and producers with information about the lithology and fluid content of the borehole while drilling. Historically it is the earliest type of well log. Under some circumstances compressed air is employed as a circulating fluid, rather than mud. Although most commonly used in petroleum exploration, mud logging is also sometimes used when drilling water wells and in other mineral exploration, where drilling fluid is the circulating medium used to lift cuttings out of the hole. In hydrocarbon exploration, hydrocarbon surface gas detectors record the level of natural gas brought up in the mud. A mobile laboratory is situated by the mud logging company near the drilling rig or on deck of an offshore drilling rig, or on a drill ship.
The Canadian Major Indoor Soccer League or CMISL is a professional indoor soccer league that began full league play in January 2008. The league's president is Felix Barraza. The indoor league's model is planned to be used to establish a professional soccer league outdoors in Canada as well.
United States Marine Corps Recruit Training is a 13-week program of initial training that each recruit must successfully complete in order to serve in the United States Marine Corps.
The 2000 UEFA Super Cup was a football match played on 25 August 2000 between Real Madrid of Spain and Galatasaray of Turkey. Real Madrid qualified by beating Valencia in the 2000 UEFA Champions League Final, while Galatasaray had made it to the Super Cup after beating Arsenal in the 2000 UEFA Cup Final. Galatasaray won the match 2–1, both goals scored by Mário Jardel, the latter a golden goal.
"For a Minute" is a song by American hip hop recording artist B.G., released as the first single from his tenth studio album, Too Hood 2 Be Hollywood. The song, which features vocals from fellow American rapper T.I., was produced by Scott Storch.
Annular velocity is the speed of a fluid's movement in a column called an annulus in wells being drilled with circulating drilling fluid. It is commonly measured in feet per minute (ft/min) or meters per minute (m/min). Annular velocity is often abbreviated as AV, though this is not exclusively so, as AV also refers to apparent viscosity which is calculated from rheometer readings from tests that the mud engineer performs.
A rotary table is a mechanical device on a drilling rig that provides clockwise rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).
Desanders and desilters are solid control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs. Desanders are installed on top of the mud tank following the shale shaker and the degasser, but before the desilter. Desander removes the abrasive solids from the drilling fluids which cannot be removed by shakers. Normally the solids diameter for desander to be separated would be 45~74μm, and 15~44μm for desilter.
The 1980–81 season was the North American Soccer League's second indoor soccer season.
Drill music is a style of trap music that originated in the South Side of Chicago in the early 2010s.
The 2013 Christy Ring Cup final was a hurling match played at Croke Park on 8 June 2013 to determine the winners of the 2013 Christy Ring Cup, the 9th season of the Christy Ring Cup, a tournament organised by the Gaelic Athletic Association for the second tier hurling teams. The final was contested by Kerry of Munster and Down of Ulster, with Down winning by 3-16 to 2-17.
