摘要： In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted. A second sleeve is connected to the first sleeve and is threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves. The third sleeve is axially displaceable between a first position and a second position. In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws. When the third sleeve is displaced into the second position, the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.

摘要： A drill chuck for a hand-held drilling device, such as a hammer drill, percussion drill or the like, includes a chuck body mounting a plurality of clamping jaws. An adjusting sleeve is rotatably mounted on the chuck body for positioning a partly frusto-conically shaped bracing sleeve for radially positioning the clamping jaws to secure or release a tool shank. The adjusting sleeve includes gear teeth which can be engaged by a ring gear key for rotating the adjusting sleeve relative to the chuck body. A locking sleeve is axially displaceably mounted on the adjusting sleeve. In a first position, the locking sleeve blocks engagement of the key with the ring gear teeth. In a second position, the locking sleeve is moved affording access by the key to the ring gear teeth so that the adjusting sleeve can be rotated and the clamping jaws radially positioned by the bracing sleeve.

摘要： In a tool holder for securing a tool in a hammer drill in a form-locking manner, locking elements are radially displaceably mounted in a guide member. An adjustment ring is threaded onto the guide member and by rotating the adjustment ring relative to the guide member, the locking elements can be adjustably tightened or loosened. The locking elements seat in closed end recesses in the shank of the tool to be secured. The adjustment ring can be locked in different rotational positions by an interlocking tooth arrangement. Teeth are provided on the adjustment ring and on a fixing sleeve axially slidably positioned on the guide member. The fixing sleeve can be moved axially between a position for locking the adjustment ring and another position permitting the adjustment ring to be rotated relative to the guide member. The surface on the adjustment ring adjustably positioning the locking elements is frusto-conically shaped so that the locking elements are radially displaceable for engaging tool shanks of different diameters.

摘要： A drill bit with an axially elongated shank is suitable for use in all known conventional hand-held drilling machines. The shank is generally cylindrically shaped with axially extending first grooves open at the free rear end face of the shank. Axially extending second grooves are superimposed at least in part on the first grooves and are spaced from the rear end face. Each second groove forms at least one shoulder face disposed transversely of the shank axis and oriented in the direction facing oppositely to the rear end face. Accordingly, the drill bit, due to its first grooves, can be utilized in the chucks presently used in drilling machines and percussion drilling machines. Further, due to the second grooves, the drill bit can be clamped for limited axial movement in the chucks of known hammer drills.

摘要： In a chuck for use in a drilling device, such as a hammer drill, capable of performing rotary or rotary/percussion drilling, clamping jaws are provided to secure a tool in the drilling device. The clamping jaws each have a convex surface transverse to the chuck axis and with the surface directed inwardly toward the axis. The more radially inward portion of the convex surface has a V-shaped notch extending in the axial direction of the chuck. The notch forms a pair of spaced edges which grip the surface of the tool secured in the chuck so that the tool can be reliably rotated.

摘要： A drill chuck usable in a drilling device capable of rotary or rotary-percussion drilling, includes radially adjustable clamping jaws with the clamping surfaces of the jaws directed inwardly towards the central axis of the chuck. Each clamping jaw has at least one projection extending radially inwardly from the clamping surface for engagement in correspondingly shaped recesses in the shank of a drilling tool insertable into the chuck. The clamping surfaces form guide surfaces for the drilling tool so that the drilling tool is adequately guided over large surfaces extending in the axial and circumferential directions in the chuck.
