The invention relates to drywall screw gun multitools and in particular to a drywall screw gun having a cutter and a dust collector.
Installation of drywall is difficult as large sheets of drywall are held in place, aligned with an adjacent sheet or fit into proper position, and fastened with nails or screws. Drywall screw guns have been developed that automatically index screws into position so that a user can insert the screws by simply pressing the head against the drywall and squeezing the trigger. These tools typically have a clutch that disengages the tool when the screw is inserted to a proper depth. Often the drywall has to be cut, such as holes for light fixtures, outlets or vents. This requires the drywall installer to put down the drywall screw gun, locate a cutting tool and cut the drywall. This switching back and forth between tools is time consuming and cumbersome for the user, especially when holding the drywall in place or working on a ladder. In addition, cutting drywall produces a lot of dust that can get into the user's face and eyes, especially when cutting drywall on the ceiling.
The invention is directed to a drywall screw gun multitool comprising a screw gun on a first end of the tool and a cutter tool on an opposing end. A drywall installer simply has to turn the tool around to switch from the screw gun tool to the cutter tool, thereby saving time and money in drywall installation. In an exemplary embodiment, the drywall screw gun multitool comprises an electric motor that spins both the screw gun and the cutter that are coupled to the single motor for operation. An exemplary drywall screw gun multitool may also comprise a dust collector assembly that draws air in from the cutter end of the tool and through a filter. An exemplary drywall screw gun multitool may also comprise a light to aid the user in low light conditions such as in tight corners or in dimly lit rooms. An exemplary drywall screw gun multitool may comprise a stud finder that will indicate when the screw gun head is located over a stud. An exemplary stud finder may illuminate when the screw gun head is correctly positioned over a stud. The cutter tool and the dust collector may be detachably attachable to the housing of the drywall screw gun multitool.
An exemplary drywall screw gun multitool comprises an electric motor that is powered by a power supply, such as batteries or through a power cord coupled with the tool. The electric motor spins both the screw gun and the cutter tool. In an exemplary embodiment, the electric motor spins a single drive shaft that extends through the motor and is coupled with the screw gun tool on one end and the cutter tool on the opposing end of the drive shaft. An auto-feed screw assembly may be detachably attachable to the drywall screw gun multitool to feed a screw into the screw gun portion of the tool and align the screw with a screw drive coupling. A user may simply have to press the screw gun end of the tool against the drywall and press the trigger to drive the screw into the drywall. The tool may automatically disengage with the screw when inserted a proper depth, such as by a clutch. A new screw may then be automatically indexed into position.
An exemplary cutter is configured on the opposing end of the drywall screw gun multitool as the screw gun and may be configured into a cutter assembly that is detachably attachable to the drywall screw gun multitool. A cutter may be configured to receive a router shaft and/or a cutter bit. The router shaft and/or cutter bit may be detachably attachable and may be configured to rotate to a stowed position when the user is using the screw gun tool. The router shaft and/or cutter bit may rotate down toward the base of the tool for example and may be at least partially stored in a recess within the housing or the cutter assembly. Optionally, the router shaft and/or cutter bit are coupled to the drywall screw gun multitool by flex wires, such as flex wires extending from the router shaft and/or cutter bit to a cutter drive coupling. The cutter bit may be attached to the tool, such as to the router shaft, by a tie bit and optionally a nut. A portion of the router shaft or cutter drive coupling may be threaded to receive the nut to secure the cutter to the tool.
An exemplary drywall screw gun multitool comprises a dust collector that may be configured in a dust collector assembly that is detachably attachable to the multitool. A fan may be driven by the electric motor to draw air in to the dust collector from the cutter end of the tool. Air containing drywall dust from the cutter tool may be drawn into the collector, through one or more filters and forced out through an outlet. A collection portion may collect the debris for removal. An exemplary collector housing is configured to be opened, to allow removal of the filters for cleaning or replacement and for emptying the collection portion of debris. The window may be configured in the collector housing to allow a user to see how much debris is in the collection portion. A collector interface, such as a button or lever, may allow a user to disengage the fan when the user is not using the cutter tool. In an exemplary embodiment, the fan is engaged automatically when the cutter assembly is attached to the tool or when the cutter tool is rotated up from a stowed position. A user may however disengage the fan using the collector interface.
An exemplary drywall screw gun multitool comprises a light that may project light toward the working end of the tool, such as the screw gun end or the cutter end. The light may pivot to allow the user to switch which end the light is projecting. A light may be configured on the dust collector assembly or directly to the housing.

The drywall screw gun multitool 10 may include an engagement switch that allows the cutter end 26 of the drive shaft 52 to spin with the motor when the cutter bit is engaged with the drive shaft 52, and disengages the screw end of the drive shaft 52 when the cutter bit 62 is engaged with the drive shaft 52. The engagement switch may allow the drywall screw gun multitool to be used in a manner so that only one side of the tool can be used at a time.

An exemplary drywall screw gun multitool comprises a stud finder 39 that alerts the user when the screw gun end is positioned over a stud. A stud finder may produce an indicating light or sound when over a stud. In addition, the stud finder 39 may pivot or rotate allowing the user to determine a stud location when using the cutter tool. A stud finder 39 may utilize sound waves or any conventional means to locate the stud. In some embodiments a light 33 may be mounted with the stud finder 39 and both the light 33 and the stud finder 39 may be rotated together to point to either the screw gun end 24 or the cutter end 26. In other embodiments the stud finder 39 and the light 33 may be on separate components, and the light 33 may rotate independent of the stud finder 39.
An exemplary drywall screw gun multitool may include one or more lights 33 such as an LED (Light Emitting Diode) light. The LED light 33 may be placed in multiple locations including on the screw gun end 24, the cutter end 26, the collector outlet 82, the multitool housing 20, or other places on the drywall screw gun multitool. The light 33 may be an LED an incandescent light, or other type of light. In some embodiments an LED light provides the advantage of lower power usage to extend the life of a battery when a system is operating using a battery as a power supply 36.
In some embodiments a stud finder 39 may include a laser to show on the wall where the stud is on the wall. A stud finder 39 may be located on one or more locations on the drywall screw gun multitool including on the screw gun end 24 and on multitool housing 20.
It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
This application claims the benefit of priority to U.S. provisional patent application No. 62/415,071, filed on Oct. 31, 2016 and entitled Multitool Drill; the entirety of which is hereby incorporated by reference herein.
