A brace or brace and bit is a hand tool used to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. The U-shaped part is a kind of crankshaft. It gives the brace much greater torque than other kinds of hand drills. A brace can be used to drill much wider and deeper holes than can a gear-driven hand drill. The price 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, but it requires considerable effort to achieve even 100 rpm with a brace.

  • Un vilebrequin est un outil utilisant la force manuelle pour percer des trous dans les matériaux (principalement le bois). Cet outil est muni d'un mandrin où l'on fixe une mèche, un foret, une fraise ou un tournevis adapté au matériau à percer et à la largeur du trou à forer. (fr)
  • Eine Bohrkurbel (auch: Bohrwinde oder Kurbelbohrmaschine) ist eine Handbohrmaschine, mit der man manuell durch Kurbeltechnik Löcher bohrt (normalerweise in Holz). Ihre gekröpfte Achse wird per Hand über eine auf ihr befindliche, locker gelagerte, außerhalb der Bohrachse kreisende Griffrolle (meist aus Buchenholz) angetrieben. Bei gehobenen Ausführungen ist auch sie kugelgelagert. (de)
  • A brace or brace and bit is a hand tool used to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. The U-shaped part is a kind of crankshaft. It gives the brace much greater torque than other kinds of hand drills. A brace can be used to drill much wider and deeper holes than can a gear-driven hand drill. The price 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, but it requires considerable effort to achieve even 100 rpm with a brace. The front part of the brace consists of a chuck spindle with V-shaped brackets or clamps inside. Turning the spindle of the chuck in a clockwise direction tightens the drill bit in the chuck and turning in a counter-clockwise direction loosens the bit for removal. In most braces, immediately behind the chuck is a three position gear release which allows ratcheting of the handle when in tight spots. Turning the gear release from the center position allows ratcheting the brace in the direction needed. Turning the gear release fully clockwise lets it remove wood in a clockwise direction with the ratchet action going counter-clockwise. Placing the gear release fully counter-clockwise then allows turning the brace and bit in a counter-clockwise direction, usually to remove the drill bit from the hole. The center position of the gear release prohibits the ratcheting effect. The U-shaped crank has a wooden spindle on it and—along with the top spindle—is allowed to freely turn under the hands without producing wear and tear on the hands (thus, no blisters). The earliest carpenter's braces equipped with a U-shaped grip, that is with a compound crank, appeared between 1420 and 1430 in Flanders. (en)

  • Il girabacchino (o girabecchino o girabarchino) è un attrezzo che serve ad imprimere un movimento rotatorio manuale. Il principio di funzionamento è lo stesso della manovella, cioè quello di un'impugnatura eccentrica rispetto all'asse di rotazione. È costituito da un'asta di metallo sulla cui lunghezza è ricavata, tramite una serie di piegature a gomito, una forma eccentrica ad U.Su una estremità dell'attrezzo si trova imperniato un pomello girevole, su cui si fa forza con il palmo di una mano (o in alcuni casi anche una piastra di appoggio per il petto). Sulla U centrale si trova una manopola anch'essa girevole, che viene impugnata dall'altra mano, che assieme al movimento del braccio imprime il moto rotatorio. Sull'altra estremità dell'attrezzo si possono applicare vari accessori, a seconda dell'uso a cui è destinato il girabacchino: * si può trovare un mandrino, ed allora si ha un trapano manuale che prende anche il nome di menarola o menaruola o trapano a manovella; * si può trovare un gancio o uno snodo o altro, ed allora l'attrezzo serve a manovrare un cric manuale o l'arrotolatore di una tenda; * si può avere una chiave a bussola, che può servire a manovrare un cric, a stringere bulloni, o a manovrare i piedini di stazionamento di una roulotte. Questi ultimi tipi hanno uno stelo lungo, la cui lunghezza varia a seconda dell'uso a cui sono destinati. (it)
  • Arco de pua é uma antiga ferramenta manual, utilizada para fazer furos em madeira. É a antecessora das atuais furadeiras elétricas. Consiste numa armação de madeira ou aço de formato característico, com local apropriado para prender a broca (ou pua, do latim puga, haste com ponta aguçada). Ferramenta tradicional, possuía também uma catraca que facilita o uso em locais apertados. Foi quase que totalmente substituída pelas furadeiras elétricas. (pt)
  • Коловоро́т — ручной инструмент для сверления отверстий в дереве и других мягких материалах, с ручкой в виде скобы (колена) и патроном для зажима свёрл, пёрок и других орудий, требующих для действия вращения вокруг оси и давления вдоль неё. В средней части коловорота — свободно вращающаяся ручка. На верхнем конце установлен гриб. На нижнем — колодка с внутренней полостью квадратного или прямоугольного сечения или патрон, в которых крепятся пёрка или сверло. Сверление производится вращением ручки при одновременном нажатии на гриб коловорота. (ru)
