A tool bit holder for connecting a rotary tool to a rotary tool driver. The tool bit holder including a body having a driver end configured to connect to a rotary tool driver and a tool end, a tool retainer bore, and a tool retainer movably received within the tool retainer bore and movable between an engaged position and a retracted position. The tool bit holder further includes an actuator sleeve, a sleeve spring for urging the actuator sleeve towards a first position, a plunger, and a plunger spring urging the plunger towards a loading position. A tool bit received in a tool receiving cavity pushes the plunger to a loaded position, and in the loading position the plunger extends over the tool retainer bore to engage the tool retainer and urge the tool retainer towards the retracted position.

An adapter for holding a tool in a collet chuck, the adapter containing an external taper to accommodate the adapter in the collet chuck. The adapter has a thread for fastening of the tool, and several shape-mated elements are arranged on an outer surface of the external taper for non-rotational holding of the receptacle body during fastening of the tool.

A wood-drill adapter system having a wood-drill adapter assembly. The wood-drill adapter assembly includes a core-bit-blank, an adapter-insert, and a set-screw. The core-bit-blank includes a hollow-tubular body, with the hollow-tubular-body including a hole; and the cap includes a cap-plate, and a threaded-coupler. The wood-drill adapter assembly is useful for allowing a user to use a coring-rotary-tool typically used for concrete drilling/coring to drill a circular-opening in a wooden-material using the wood-boring tool. The adapter-insert includes an upper-disc, a tubular-body, a lower-disc, and a set-screw-receiver. The upper-disc includes an upper-face, a lower-face, an outer-circumference, and an upper-aperture. The lower-disc includes an upper-surface, a lower-surface, an external-circumference, and an internal-circumference. The tubular-body includes an outside-circumference, an inside-circumference, an upper-rim, and a lower-rim.

A quick release connector is provided, including: a main body, including a tubular section which defines an axial direction, the tubular section including an inner hole, an insertion opening communicating with the inner hole, a slanted groove communicating with the inner hole and a sliding groove axially extending and communicating with the inner hole, the slanted groove extending inwardly toward the insertion opening; an elastic abutting mechanism, abutted within the inner hole, for urging an insert member to insert into the inner hole via the insertion opening; a locking mechanism, including a pin portion and a locking portion, the pin portion disposed through the sliding groove and axially slidably movable together with the elastic abutting mechanism, the locking portion received in the slanted groove and radially projectable into the inner hole, the locking portion movable together with the pin portion and the elastic abutting mechanism.

A power tool including a motor and a rotatable spindle driven by the motor to hold and drive a first bit. There is a recess located on the spindle. The power tool also includes a removable chuck with a lock member and a locking collar. The locking collar includes a locking position in which the locking collar biases the lock member into the recess to retain the chuck on the spindle. The locking collar also includes a release position in which the lock members are able to exit the recess and the chuck is able to be removed from the spindle by a user. The locking collar is axially movable from the locking position to the release position.

A tooling exchange mechanism and a machine tool having the tooling exchange mechanism, in which a load applied to a turret is reduced when exchanging a tooling in the machine tool, are provided with a pressing member 210 of a tooling detachment unit 200 that presses the rear end of a tooling holding unit 100 to be able to release the retracted state of a tool holder Th of a tooling T by a tool holder holding portion 150 of the tooling holding unit 100, and a locking lever 220 of the tooling detachment unit 200 engageable with an engaging projection 112a formed on the rear end side of the tooling holding unit 100.
