A gimlet is a hand tool for drilling small holes, mainly in wood, without splitting. It was defined in Joseph Gwilt's Architecture (1859) as "a piece of steel of a semi-cylindrical form, hollow on one side, having a cross handle at one end and a worm or screw at the other".
A bow drill is a simple rotational hand-operated tool of prehistoric origin. As a "fire drill" it commonly was used to generate friction to start a fire. With time it was adapted to woodworking and other tasks requiring drilling, such as dentistry.
A screwdriver is a tool, manual or powered, for screwing and unscrewing screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional 'grip'. Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that contains various types and sizes of tips, and a reversible ratchet action that allows multiple full turns without repositioning the tip or the user's hand.
Drill is stout durable cotton fabric with a strong bias (diagonal) in the weave. It can be used unbleached, although it is more often bleached or dyed.
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.

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.
A self-tapping screw is a screw which can tap its own hole as it is driven into the material.
A drilling rig is a machine that creates holes in the earth's subsurface. Drilling rigs can be massive structures housing equipment used to drill water wells, oil wells, or natural gas extraction wells, or they can be small enough to be moved manually by one person and such are called augers. Drilling rigs can sample subsurface mineral deposits, test rock, soil and groundwater physical properties, and also can be used to install sub-surface fabrications, such as underground utilities, instrumentation, tunnels or wells. Drilling rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land or marine-based structures. The term "rig" therefore generally refers to the complex equipment that is used to penetrate the surface of the Earth's crust.
A keyhole saw is a long, narrow saw used for cutting small, often awkward features in various building materials. There are typically two varieties of keyhole saw: the fixed blade type and retractable blade type.
"E.I." is a single by American rapper Nelly. It was released in 2000, taken from Nelly's 2000 album Country Grammar. It peaked at number 11 on the UK Singles Chart and 16 on the U.S. Billboard Hot 100.
A via or VIA is an electrical connection between layers in a physical electronic circuit that goes through the plane of one or more adjacent layers. To ensure via robustness, IPC sponsored a round-robin exercise that developed a time to failure calculator.
In the context of machining, a cutting tool or cutter is any tool that is used to remove material from the work piece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, planing and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools. Grinding tools are also multipoint tools. Each grain of abrasive functions as a microscopic single-point cutting edge, and shears a tiny chip.
The Mikan Drill is a basketball drill commonly credited to George Mikan and Ray Meyer. It is designed to help basketball centers and forwards develop rhythm, timing for rebounding, and scoring in the paint. It is also used for outside players to better their layup skills and increase stamina, for longer games.
Gun drills are straight fluted drills which allow cutting fluid to be injected through the drill's hollow body to the cutting face. They are used for deep drilling—a depth-to-diameter ratio of 300:1 or more is possible. Gun barrels are the obvious example; hence the name. Other uses include moldmaking, diemaking, and the manufacture of combustion engine parts such as crankcase, cylinder head, and woodwind musical instruments, such as uilleann pipes, as gun drills can drill long straight holes in metal, wood, and some plastics. The coolant provides lubrication and cooling to the cutting edges and removes the swarf or chips from the hole. Modern gun drills use carbide tips to prolong life and reduce total cost when compared with steel tips. Speed of drilling depends on the material being drilled, rotational speed, and the drill diameter; a high speed drill can cut a hole in P20 steel at 30 inches per minute.
A punch is a hard metal rod with a sharp tip at one end and a blunt butt end at the other, which is usually struck by a hammer. Typically, woodworkers use a ball-peen hammer to strike a punch.
The Marching Jayhawks, is a 270-piece marching band consisting of woodwinds, brass, percussion, and color guard, representing the University of Kansas in Lawrence, Kansas. The band performs at all home football games and occasionally travels to away games. They also send smaller ensembles to pep rallies around the Kansas City area. The band marches in parades on campus and in downtown Lawrence. The volleyball and basketball pep bands play at all home games and will often travel for post-season play. The band was awarded the Sudler Trophy in 1989.
"P-Poppin'" is the first single from Ludacris's fourth album Chicken-n-Beer. It features Shawnna and Lil Fate. The song samples "Danger " by Mystikal, and depicts what goes on in a strip club and a dance that can be done with or without clothes.
