A power tool adapter for both standard drills and impact drivers includes a shank or drill coupler including a head, a neck or clip retainer integrally connected to the head, and an extender integrally connected to the clip retainer; a drill bit locker integrally connected to the drill coupler and specifically integrally connected to the extender, and a sleeve engager integrally connected to the drill bit locker. The power tool adapter is configured to simultaneously hold or engage a drill bit and a torque sleeve.

A toolholder assembly includes a toolholder having a toolholder shank with a non-circular cross-section, a base member having a bore with a non-circular cross-section that receives the toolholder shank, a canister positioned in the base member, a lock rod positioned in the canister, a locking ball for cooperating with the lock rod, the canister and/or the toolholder shank and an actuating element configured for cooperation with the lock rod for moving the lock rod between a locked position and an unlocked position.

A tool holder includes a collet configured to be clamped to the shank of a tool and a pull-out protection element configured to secure the tool against being pulled out of the collet. The pull-out protection further includes a protection element such that pull-out forces acting on the tool are transmitted to the collet. The protection element is mounted so as to be moveable relative to the collet and has a wedge-shaped configuration as well as force-transmission surface. When the protection element is in a radially inner engaged position with the tool, the protection element is configured to be clamped to the cool and the collet so as to be self locking.

A cutter holder has a holding segment and a flange. The holding segment has a triangular cross section, a first end, a second end, and a central hole. The second end is opposite the first end. The central hole is axially defined in the first end of the holding segment. The flange is disk-shaped, is coaxially formed on the second end of the holding segment, and has a periphery, an identifying hole, and a connecting hole. The identifying hole is radially defined in the periphery of the flange. The connecting hole is axially defined through the flange, communicates with the central hole in the holding segment, and has an inner thread formed in the connecting hole.

The present invention provides a fluidic clamping device (100) comprising a sleeve (110) for clamping and holding a movable part (200). The sleeve (110) comprises a central element (111) having a cross-section in a longitudinal direction of the central element (111), comprising a cavity configured to receive the movable part (200). The fluidic clamping device (100) is characterized in that the sleeve (110) further comprises at least one chamber (112) disposed on an outer periphery of the central element (111) and extending along a longitudinal direction of the central element (111), the at least one chamber (112) configured to containing a fluid, wherein the fluidic clamping device (100) is configured to pressurize an interior of the at least one chamber (112) with a first predetermined fluidic pressure or a second predetermined fluidic pressure, wherein the first predetermined fluidic pressure is lower than the second predetermined fluidic pressure, and wherein the central element (111) is configured to be in frictional contact with the movable part (200) at at least a portion of an inner periphery of the central element (111) and to clamp and hold the movable part (200) in a first state in which the interior of the at least one chamber (112) is pressurized with the first fluidic pressure, and wherein the central element (111) is configured not to be in frictional contact with the movable part (200) at any portion of the inner periphery of the central element (111) in a second state in which the interior of the at least one chamber (112) is pressurized with the second fluidic pressure.
