Provided is a processing tool capable of sliding a tool relative to a shank with a simple structure, to which a tool holder is detachably attached. The processing tool to which the tool is detachably attached, includes: a body; a spindle including tool holder holding hole, a first anti-rotation body holding hole; a cover including a pressing surface and a relief portion; a tool holder detachably inserted into the tool holder holding hole, the tool holder including a first anti-rotation groove, a tool holding hole, and a first spring holding hole, an anti-rotation body movable between the first anti-rotation groove and the pressing surface, the anti-rotation body accommodated in the relief portion when the cover is located at the detachable position and the tool holder is removed from the tool holder holding hole; and an elastic member to urge the tool holder toward distal end.

A device adapted to releasably lock with a bolt, the device comprising a front cover having a cavity which extends from the front cover to a rear portion of the device, wherein the cavity is adapted to receive the bolt with mounting concave portions for mounting the bolt in the cavity; a locking mechanism comprising a first group of locking shape, wherein the first group of locking shapes is moveable between a first position and a second position, wherein the first position is in the cavity, and the second position is in a corresponding first group of locking shape recesses. A moveable block comprising the first group of locking shape recesses; wherein disengagement of the first group of locking shapes is activated by movement of a release plate thereby allowing the first group of locking shapes to retract from the cavity into the first group of locking shape recesses.

A bit holder is provided including a tool bit receiver body operably configured to receive at least a portion of a tool bit, a retention element configured to retain the tool bit engaged within the tool bit receiver body, a release configured to disengage the retention element enabling removal of the tool bit, a drive element operably coupled to the tool bit receiver body and configured to transfer axial rotation from a driving tool to the tool bit receiver body, and a sleeve disposed around at least a portion of the bit holder and configured such that the tool bit receiver body rotates independent of the axial rotation of at least a portion of the sleeve.

A deburring method includes rotating a case, a sleeve and a drive gear together with a spindle of a machining tool; transmitting rotating torque from the drive gear to a driven gear to rotate a tip tool together with a reciprocating shaft; receiving reactive torque to the tip tool in a reverse direction of a rotational direction of the case by a workpiece contact with the tip tool so that the reciprocating shaft rotates in a reverse direction of the rotational direction with respect to the sleeve; moving the reciprocating shaft to a basal end direction against an elastic force of a second spring with the driven gear sliding with respect to the drive gear; and cutting the workpiece by the tip tool.

A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge with an extended finger is oriented over a fluid connection to a socket guide. The sleeve is oriented to the tool collar to place a flexible hinge and finger over the bearing guide. The finger moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the finger in the tool socket while allowing necessary movement to insert and remove a tool.

A multi-size tool bit holder includes a first sleeve with a first bit holding bore extending along an axis and a first accommodating bore extending through a sidewall of the first bit holding bore, a second sleeve coupled for co-rotation with the first sleeve and movable relative to the first sleeve between a first position and a second position, the second sleeve including a second bit holding bore extending along the axis and a second accommodating bore extending through a sidewall of the second bit holding bore, and a retaining element. The retaining element has a first securing position in which the retaining element extends through the first and second accommodating bores when the second sleeve is in the first position and into a groove in a bit shank to axially secure the bit shank within the second sleeve.

A deburring tool includes: a case; a hollow sleeve that reciprocates inside the cylinder in a non-rotating manner; a drive gear disposed inside the sleeve, includes a first tooth, and rotates together with the case and the sleeve; a reciprocating shaft disposed inside the sleeve, including a driven gear disposed at a basal end portion of the sleeve and a basal end side of the drive gear, the driven gear including a second tooth, a tool holder disposed at a distal end portion of the sleeve, and slides inside the sleeve in a rotational and reciprocating direction, and a stem that fixes the driven gear and the tool holder, and penetrates the drive gear, a first spring that urges the sleeve toward distal end direction; and a second spring that urges the tool holder from the drive gear toward distal end direction.

Tool adapter assemblies are presented including: a quick release coupler including: a spindle defining a partial cylindrical cavity, the spindle including a base portion, a body portion, and an end portion where the body portion includes a number of ball stop recesses; a number of ball stops slidingly engaged with the number of ball stop recesses; and a sleeve slidingly coupled with the spindle, where the sleeve is configured to lock and release the ball stops; and an accessory connector including at least one of: one or more annular grooves configured to engage with number of ball stops, a number of detents configured to engage with number of ball stops, or both the annular groove and the number of detents; and an accessory engagement portion positioned along a proximal end of the accessory connector.

A hole cutting accessory for a power-driven tool may include an arbor that provides for quick release of an annular saw blade component of the accessory, and for quick release of a pilot drill bit component of the accessory. The quick release of the annular saw blade component from the arbor may be accomplished separately from the quick release of the pilot drill bit component from the arbor.
