Embodiments relate to a power drive adapter tool. The tool includes a drive adapter and a drill bit assembly. The drive adapter includes a body having a first end and a second end, the first end having a drive-receiving aperture configured to receive a drive from a drive tool, and the second end having a bit-receiving aperture configured to receive the drill bit assembly. The drill bit assembly has a drill bit and a connector, the connector having a proximal end and a distal end. The drill bit is permanently connected to the distal end, and the proximal end is configured to insert into the bit-receiving aperture.

An illuminated drill bit assembly for illuminating a work area for a drill without casting a shadow includes a drill bit that can be inserted into a chuck of a power drill. The drill bit has a well integrated therein for insertably receiving an additional drill bit. A cylinder is provided and the drill bit extends through the cylinder. A lighting unit is integrated into the cylinder to emit light outwardly from the cylinder when the lighting unit is turned on. In this way the lighting unit can illuminate the work area without casting a shadow.

An apparatus in the form of an adapter for forming a connection comprising a first part adapted for coupling with a second part by a quick-release coupling formed by a first projection of the first part having an at least partial dovetail shape and a recess of the second part having an at least partial dovetail shape. An opening in the recess is adapted for receiving the projection in an axial direction. In other embodiments, the adapter is: (1) frictionally enhanced for engaging an internal portion of the drilling element; (2) includes a radial projection elongated in an axial direction for engaging the internal portion of the one drilling element; and/or (3) has a cutter for scoring an internal portion of the one drilling element upon being inserted therein and rotated. An adapter is also disclosed for use with a drill check, including for creating a “twist lock” connection.

The present invention discloses an industrial high speed micro drill that is made to access remote and inaccessible locations in order to blend, grind, polish and cut materials and parts as determined by visual inspection powered via a pneumatic power source. The high speed drill is deployed by a controlled, articulating guide tube that acts in a multidirectional fashion to direct the action of the assemblage and allow for discrete manipulation of the pneumatically powered drill while harboring a channel and pneumatic power source carrying rubber tubing.

Hole saw adapter (10) comprised of an adapter body (12) with a first end equipped with a spindle (14) for fastening to a drive unit, such as a drilling machine, and a second end to receive a hole saw (32) and a central drill (34), in which the adapter body (12) is extended and equipped with a longitudinally running axial groove (16) where the longitudinally running axial groove (16) is at least partially formed as a cross-wise through-running open slit in the adapter body (12). The central drill (34) is fasten to the inner axially displaceable holding part (22) so that it can be made loose, said inner axially displaceable holding part (22) can be displaced in the longitudinally running axial groove (16) in the adapter body (12) and is fastened to an external displacement part (18), as the external displacement part (18) surrounds the adapter body (12) and is set up for a forced axial displacement of the axially displaceable holding part (22) and the central drill (34) in the longitudinally running axial groove (16) for the pushing out of a core (40) that remains in the hole saw (32) after drilling.

A quick-changing brazed drill includes a drill body and a quick-changing joint. The drill body is connected to the quick-changing joint detachably, and a vent hole is provided at a connection point between the drill body and the quick-changing joint. The drill body has a cylindrical structure, an interior of a front end of the drill body is hollow, and an outer side of the front end of the drill body is provided with 2-6 grooves. The quick-changing joint includes a transition block and a rear cover; a rear end of the transition block is connected to the rear cover by an external thread; a snap-fit area is provided between the transition block and the rear cover; a middle portion of the transition block is provided with a first threaded hole and is connected to a rear end of the drill body.

A retractable drill chuck system that is capable of being attached to a drill and drill bit; it can detect the initial breakthrough of the drill bit in a material and is capable of retracting the drill bit right as the drill bit breaks through the material; it has torque, force, and acceleration sensors to detect the breakthrough event of a drill bit; it also has an electromechanical mechanism to retract the drill bit from the material once the breakthrough event has been detected by the system; the retraction mechanism has a permanent magnet holding solenoid that, when activated, releases stored mechanical energy to allow the drill bit to be retracted.

A tool holder includes a main body defining a mounting end and a receiving end, the mounting end positioned opposite from the receiving end, the main body defining a main body bore extending into the receiving end toward the mounting end; an extension defining a tool head attached to a rod, the tool head defining a tool head end opposite from the rod, a tool holder length defined between the mounting end and the tool head end, the tool head configured to receive at least one cutting tool, the rod received within the main body bore; and a locking mechanism engaging the extension and the main body in a locked position, the locking mechanism being disengaged from either the main body or the extension in an unlocked position, the locking mechanism being selectively positionable about and between the locked position and the unlocked position.
