An apparatus for the collection, gathering, and disposal of the debris that is created when drilling a hole into a vertical surface. The Disposable Drill Debris Eliminator (DDDE) is designed and constructed in a very simple manner and is thus very inexpensive to manufacturer; the DDDE is designed and constructed so that it is foldable, stackable, and thus very compact; the DDDE it is disposable; the DDDE contains in its design, a method of alignment, which enables the user to align the drill more easily to the intended hole position in a more perpendicular manner; the DDDE contains in it's design and construction, a device that enables the user to control the depth of the hole being drilled; and the DDDE is re-positionable for many uses because the adhesive strength is of the strength of re-positionable sticker notes.

A dust collection device for an electric power tool includes a main body case that includes an air exhaust port and is attachable to a hammer drill, a dust box provided therein with a filter, and a tubular sliding portion that has a base end connected to a connection port provided on the main body case, that includes a suction port at its front end, and that is slidable in a front-rear direction, and includes therein a dust collection path formed to pass from the suction port through the filter to the air exhaust port. The connection port is provided on a side surface of the main body case, and connected to a flexible hose serving as a base end of the sliding portion, and a side surface of the dust box is provided with an inlet port communicating with the connection port.

In an example, a clamp foot for a clamp assembly includes a housing having a distal end for engaging a workpiece, an aperture in the distal end of the housing, and a cavity in the housing extending proximally from the aperture. The clamp foot also includes a flapper in the cavity and adjacent to the distal end. The clamp foot further includes a pneumatic port in the cavity configured to direct a pneumatic force from a pneumatic source to the flapper, and a vacuum port in the cavity for coupling the cavity to a vacuum source. Responsive to the pneumatic force, the flapper is movable within the cavity to separate debris from the workpiece. The vacuum port is configured to remove from the cavity, via a vacuum force from the vacuum source, the debris separated from the workpiece by the flapper.

A dust vacuuming drill device is adapted to be connected with a vacuum suction device by a socket, and includes a drill bit and a driven shank threadedly engaged with each other and cooperatively defining therein an internal dust passageway in communication with the socket for removing the dust generated during a drilling operation. The drill unit can be removed from the driven shank when the drill unit is broken so as to readily replace the drill unit without the need to detach the driven shank from the socket, which results in low operation and material costs.

A self-adjusting pocket hole jig system is presented having a base, an upright assembly operably connected to the base, a clamp and drill guide assembly operably connected to the upright assembly, and an actuator assembly operably connected to the clamp and drill guide assembly. The clamp and drill guide assembly is configured to move along the upright assembly in response to movement of a handle of the actuator assembly upward and downward. Movement of the handle downward automatically adjusts the height of the clamp and drill guide assembly based on thickness of the workpiece for drilling of a pocket hole. In one or more arrangements, rotation of the handle downward from a non-clamping position to a clamping position simultaneously locks the clamp and drill guide assembly in place along the upward assembly and clamps the workpiece between the clamp and drill guide assembly and a backstop of the base.

A hole expansion device includes a cutting portion main, body formed to have a diameter for the cutting portion, main body to be housed within a joint hole and including a cutting blade tool movable in a range from a housed position at which a blade is housed within a diameter for the cutting portion main body to an extended position at which the blade projects out of the diameter, an advancing and retracting member that is constructed to move in an axial direction by an external force and rotate about an axis of the advancing and retracting member, and a link mechanism that converts an advancing and retracting movement of the advancing and retracting member into a rotational movement of the cutting blade tool.

A drilling end effector may include a motor operative to drive a drilling member, a housing surrounding the motor, and a vacuum shroud coupled to the housing and surrounding the drilling member, wherein the vacuum shroud has a variable length.

A debris collecting rotary tool attachment for collecting debris during rotary tool use includes a shell that comprises a wall. The wall extends from a top to a bottom of the shell and has an inner face. The inner face is tackified, such that the inner face is configured to sequester debris on the inner face of the shell. The top and the bottom are open, defining respective perimeters. A fastener is coupled to the bottom and extends around the perimeter of the bottom. The fastener is configured to sealably couple the shell to a chuck end of a rotary tool. The shell is positioned around a cutting tool secured in the chuck of the rotary tool. The inner face is tackified to sequester debris generated during operation of the rotary tool.

This device is provided with: a main shaft (20) onto which a tool (100) is detachably mounted; a rod (30) slidably supported by the main shaft (20) and configured to attach or detach the tool (100) to or from the main shaft (20) through a sliding action; a fluid channel (32) formed in the rod (30); fluid feed device (51, 70) configured to feed a fluid into the fluid channel (32); a plurality of fluid channels for seating detection (24) for detecting when the main shaft (20) and the tool (100) are in a seated state, the fluid channels for seating detection (24) being formed in the main shaft (20) so as to communicate with the fluid channel (32) when the rod (30) is positioned at a first position; and a plurality of fluid channels for cleaning (25) for cleaning seating portions of the main shaft (20) and the tool (100), the fluid channel for cleaning (25) being formed in the main shaft (20) so as to communicate with the fluid channel (32) when the rod (30) is positioned at a second position different from the first position.
