Abstract: A drill chuck and a drill apparatus is provided that includes a drilling machine, which has a motor and a machine spindle that is supported in rotary fashion in a machine housing. The a drill chuck is connected to the machine spindle and can be moved between a clamping configuration and a drilling configuration and has a clamping sleeve and a chuck body in which clamping jaws are movably guided by a threaded connection. When a sliding sleeve is moved relative to the chuck body between a first position that corresponds to the clamping configuration and a second position that corresponds to the drilling configuration, a flow of force traveling from the motor via the machine spindle to the threaded connection is shifted to a flow of force traveling from the motor via the machine spindle to the chuck body and vice versa.

Abstract: A collet for connecting a tool to a driver includes a shaft having an end. The collet includes a body including a first end that connects to the driver and a second end having an internal space partially defined by a frustoconical bore and a plurality of jaws disposed within the space. Each of the jaws includes a body having a frustoconical surface arranged to engage the frustoconical bore and an engagement member coupled to each body to move between an unlocked and a locked position. Rotation of the tool about the axis in a first direction biases the engagement member toward the unlocked position to allow movement of the tool with respect to the jaws, and rotation of the tool about the axis in a second direction opposite the first direction biases the engagement member toward the locked position wherein the tool is fixed with respect to the jaws.

Abstract: A drill-chuck body is rotatable about an axis and formed with a plurality of passages opening axially rearward at a rear face of the body and radially outwardly at windows in a side of the body. Jaws displaceable between front and rear positions in the passages each have a row of teeth exposed radially outwardly at the respective windows. A tightening ring rotatable about the axis is formed with an internal screwthread engaged at the windows with the teeth such that rotation of the ring moves the jaws between the front and rear positions. A tightening sleeve fitted around and coupled rotationally to the tightening ring extends axially rearward past the windows. This brace ring is radially inwardly engaged with the body and engages radially outwardly between the windows and the rear face with the tightening sleeve so as to coaxially center it on the body.

Abstract: A chuck including a body with a nose section defining an axial bore formed therein, a plurality of jaws movably disposed with respect to the body, and a sleeve rotatably mounted about the body so that rotation of the sleeve moves the jaws relative to the axial bore. A bearing has a first race, a second race, and at least one bearing element disposed therebetween, one of the first race and the second race defining a ratchet and the other defining a pawl biased toward the ratchet. A biasing element is disposed between the pawl and the sleeve. The biasing element exerts a biasing force on the pawl toward the ratchet and the ratchet and the pawl prevent the second race from rotating in the opening direction with respect to the first race when engaged.
