Auger (drill)
An auger is a device to drill wood or other materials, consisting of a rotating metal shaft with a blade at the end that scrapes or cuts the wood. Types The classical design has a helical screw blade winding around the bottom end of the shaft. The lower edge of the blade is sharpened and scrapes the wood; the rest of the blade lifts the chips out of the way. It is powered with two hands, by a T-shaped handle attached to the top of the shaft. More modern versions have elaborated auger bits with multiple blades in various positions. Modern versions also have different means to drive the shaft, resulting in various tools such as braces, wheel drills (the "eggbeater" drill), and power drills.

Helix
A helix (; ) is a shape like a cylindrical coil spring or the thread of a machine screw. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word ''helix'' comes from the Greek word , "twisted, curved". A "filled-in" helix – for example, a "spiral" (helical) ramp – is a surface called a '' helicoid''. Properties and types The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A circular helix (i.e. one with constant radius) has constant band curvature and constant torsion. The slope of a circular helix is commonly defined as the ratio of the circumference of the circular cylinder that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw (simple Machine)
The screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called '' threads'' around the outside. The screw passes through a hole in another object or medium, with threads on the inside of the hole that mesh with the screw's threads. When the shaft of the screw is rotated relative to the stationary threads, the screw moves along its axis relative to the medium surrounding it; for example rotating a wood screw forces it into wood. In screw mechanisms, either the screw shaft can rotate through a threaded hole in a stationary object, or a threaded collar such as a nut can rotate around a stationary screw shaft. Geometrically, a screw can be viewed as a narrow inclined plane wrapped around a cylinder. Like the other simple machines a screw can amplify force; a small rotational forc ...

Auger Bit
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 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. Drills come in standardized drill bit sizes. A comprehensive drill bit and tap size chart lists metric and imperial sized drills alongside the required screw tap sizes. There are also certain specialized drill bits that can create holes with a non-circular cross-section. Characteristics Drill geometry has several characteristics: * The spiral (or rate of twist) in the drill bit controls the rate of chip removal. A fast spiral (high twist rate or "compact flute") drill bit is used in high feed rate applications under low spin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brace (tool)
A brace is a hand tool used with a bit (drill bit or auger) to drill holes, usually in wood. Pressure is applied to the top while the handle is rotated. If the bit's lead and cutting spurs are both in good working order, the user should not have to apply any pressure other than for balance: the lead will pull the bit through the wood. Bits used to come in a variety of types but the more commonly used Ridgeway and Irwin-pattern bits also rely on a tip called a snail, which is a tapered threaded screw that pulls the bit forward. The U-shaped handle is a crank. It gives the brace much greater torque than other kinds of hand-powered drills. A brace and bit can be used to drill wider and deeper holes than can a geared hand-powered drill. The cost of the greater torque is lower rotational speed; it is easy for a geared hand drill to achieve a rotational speed of several hundred revolutions per minute, while it would require considerable effort to achieve even 100 rpm with a brace. ...

Drill
A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for surgery, dentistry, miniatures, and other applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Augerino
The augerino is a legendary creature present in the folk tales of lumberjack and ranching communities in the western United States.Carol Rose, ''Giants, Monsters, and Dragons: An Encyclopedia of Folklore, Legend and Myth''. Norton, 2001, pp. 30-31.Google Books link Tales of the augerino described it as a subterranean creature which inhabited the drier regions of Colorado. The augerino required a dry environment to survive and would bore holes in dams and irrigation ditches to let the water drain out. Some accounts described the augerino as a type of worm, though tales differ on the exact physical description of the creature. The name appears to derive from the diminutive of the common hand tool, the auger. A 1941 investigation of the folk tales of Middle Park, Colorado uncovered stories of the augerino describing it as a gigantic, corkscrew-shaped, indestructible wormlike creature which lined its burrows with a silica substance to keep them from collapsing.Ronald L. Ives, "Folklor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gimlet (tool)
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 gimlet is always a small tool. A similar tool of larger size is called an auger. The cutting action of the gimlet is slightly different from an auger and the initial hole it makes is smaller; the cutting edges pare away the wood, which is moved out by the spiral sides, falling out through the entry hole. This also pulls the gimlet further into the hole as it is turned. Unlike a bradawl, pressure is not required once the tip has been drawn in. The name ''gimlet'' comes from the Old French , , later , probably a diminutive of the Anglo-French , a variation of "guimble", from the Middle Low German (cf. the Anglo-Norman language">Anglo-French , a variation of "guimble", from the Middle Low German (cf. ...
