A template kit for assisting with the drilling of holes and the mounting of objects to a planar surface. The template kit includes an impactor, a plurality of punch heads removably securable to the impactor, and a sheet of material having a first side and a second side. The first side includes a first adhesive that can releasably secure the object to be mounted. The second side includes a second adhesive that can secure the device to a wall or other planar surface. The second adhesive has increased adhesive strength relative to the first adhesive. Each punch head includes an inner and outer edge that can cut a disc member from the sheet of material, wherein the impactor drives the punch head through the sheet of material. In use, the disc members are secured to a wall and serve as a guide for drilling a hole to hang the object.

A drill bit stabilizer and a method of drilling holes through work surfaces. The drill bit stabilizer includes an adhesive strip with a drill guide hole portion extending outwardly therefrom. The adhesive strip with the drill guide hole portion is preferably transparent and portable for placement on a surface through which a hole is to be drilled. The method includes the steps of providing an adhesive strip with a drill guide hole portion extending therefrom; positioning the adhesive strip on a surface; releasably mounting the adhesive strip to the surface; inserting a drill bit attached to a drill motor into the drill guide hole portion; drilling a hole through the drill guide hole portion and into the surface beneath it; and removing the adhesive strip from the surface after the hole has been drilled.

The present application provides a magnetic tapping guide device to guide a tap for threading in a workpiece. The magnetic tapping guide device includes a guide seat configured to contact with the workpiece; a guide portion positioned outside the guide seat, having a pilot hole for guiding the tap; and a magnetic module positioned inside the guide seat, configured to provide a magnetic force to keep the guide seat in contact with the workpiece, the magnetic force of the magnetic module being adjustable.

An apparatus includes a base defining at least one through-hole configured to receive a cutter. The apparatus further includes a plurality of substantially aligned retractable rollers disposed at least partially within a plurality of recesses of the base. Each roller of the plurality of substantially aligned retractable rollers is retractable in a direction normal to a surface of the base.

A positioning device for drilling tools of various sizes contains: a body and an accommodation case. The body includes an inserting portion with at least one positioning structure configured to insert drilling tools of various sizes. The body also includes at least one mounting set configured to mount the body on a working face, an inlet defined on a top thereof, and a channel defined in a bottom thereof and communicating with the inlet and the inserting portion. The accommodation case is configured to accommodate coolant and includes an outlet formed on a first end thereof and an air hole arranged on a second end thereof. Between the accommodation case and the body is defined a connection structure configured to connect the accommodation case with the elongated plate and to align the outlet of the accommodation case with the inlet of the body.

An assembly for guiding a drill bit of a drill assembly comprises a chassis and a centering bushing, comprising an exterior conical portion and a central opening. The assembly further comprises a vacuum-cup bracket, coupled to the chassis and adjustably positionable relative to the chassis along a second axis. The assembly also comprises vacuum cups, coupled to the vacuum-cup bracket. The assembly additionally comprises a pressure foot, coupled to the chassis at the first end of the chassis and adjustably positionable relative to the chassis along the second axis.

Disclosed is a core drill guide apparatus for providing a guide for a core drill apparatus to drill into a substrate to form a removable core. The apparatus includes an elongate body with an outer surface and inner space, having an entrance end, an exit end and side walls, a distance between the ends defining a length or height of the elongate body and a width. An passageway extends through the elongate body from entrance to exit end, adapted so that in use, it provides sliding receipt of a fastening system to clamp the apparatus to an outer surface surrounding a first hole in a substrate, allowing the apparatus to abut the outer surface and drill out a core in the substrate underneath and surrounding the first hole. A corresponding guide method and fastening system are also disclosed.

According to one implementation, a hole finishing tool includes a reaming cutter and a holder. The reaming cutter has a first detaching structure. The first flow path for ejecting cutting oil is formed inside the reaming cutter. The holder has a second detaching structure. The second detaching structure is detached from and attached to the first detaching structure. The second flow path for supplying the cutting oil to the first flow path is formed inside the holder. The holder has a shank. The shank is held by a tool rotating device. The holder has a sliding portion. The sliding portion has no back taper. The sliding portion is inserted into a positioning bush and slid inside the positioning bush. The sliding portion has a concave portion for storing lubrication oil.

A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.
