A drilling aid system which comprises a body with a first cavity, a shaft mounted to be able to rotate within the first cavity, a slider which has a proximal end mounted to be able to move in translation within the first cavity, where the slider has a second cavity which extends the first cavity, a collar that is able to move in translation on the shaft, a first compression spring having a first stiffness and pressing against the collar and against the proximal end of the slider, and a second compression spring having a second stiffness greater than the first stiffness, and pressing against the collar and against the proximal end of the body. A system of this kind makes it possible to make the user perceive that the end of the drilling operation is nigh and that therefore the force applied to the drill should be reduced.

An auto-adjusting pocket hole jig docking station including a housing and an adjustment mechanism. The adjustment mechanism carried by the housing and including a first rack and a second rack reciprocally movable between raised and lowered positions, relative the body. A double pinion gear is rotatably carried by the housing with a first gear in meshing engagement with the first rack and a second gear in meshing engagement with the second rack. The first gear and the second gear having a rotational ratio therebetween wherein movement of one of the first rack and the second rack moves the other of the first rack and the second rack a distance proportional to the rotational ratio.

A depth-indicating device for determining the depth of insertion of a surgical tool comprising a pair of spaced apart end caps, separated by a compressed spring, with the surgical tool passing through axial openings in both end caps, and firmly attached to one of the end caps, but free to slide through the opening in the other. A guide tube is attached to the second endcap, such that the surgical tool can be guided to its operating position on a body part. The second end cap and guide tube are attached to a location having a known position relative to the body part. A tracking marker is attached to the first end cap such that its longitudinal position can be tracked using a remote racking camera. Since the surgical tool is attached to the first end cap, the tool position is also tracked by the tracking system.

In one embodiment, a system includes a counterbore drill bit, pre-cut lead rods of predetermined length, and a tapper tool. The counterbore drill bit includes a stop collar to drill counter bored holes with a first hole portion having a first diameter to a first depth below a surface of a material and a second hole portion having a second diameter less than the first to a second depth below the surface. The lead rods are inserted into the counter bored holes. The tapper tool mashes the second end of each lead rod in the one or more counterbored holes to expand and friction fit then in the counter bored holes. The system further includes circular survey tags insertable into the first hole and fasteners with a head and a shaft insertable through a center hole in the survey tags to retain the tags coupled to the lead rods.

Various embodiments of power tool and method of operating same are described. The power tool may include a first position sensor, a second position sensor, a third position sensor, and a controller. The first, second, and third position sensors may each generate a signal indicative of a distance between the respective position sensor and a workpiece. The controller may determine one or more angles of the power tool with respect to the workpiece based on the first, second, and third signal and present an indication as to whether the one or more angles are within a predetermined range. The controller may further obtain a depth measurement based on the first signal, the second signal, and the third signal and generate, based on the obtained depth measurement, one or more control signals that control operation of the power tool.

A hole-saw comprises a tubular body connectable at one end to inter alia a power drill and formed at its other end with an annular array of cutting teeth. A collar is positioned at the end of the tubular body remote from the cutting teeth, the perimeter of the collar extending generally normal to and beyond the perimeter of the tubular body.

The disclosure relates to a machining station for machining platelike workpieces (1) by means of at least one tool (10, 13, 14). The machining station has a measuring device (16) for acquiring data relating to the position of bores, a drill (10, 13, 14) for generating bores in the workpiece (1), and a data processor (17) for processing data of the at least one measuring device (16) and/or for controlling the at least one drill (10, 13, 14). The data processor (17) is here suitable and set up for performing an adjustment between a desired drilling position and/or a desired bore depth and an actual position and/or actual depth as determined by the at least one measuring device (16) for a bore present in the workpiece (1), and adapting the drilling position and/or bore depth for generating bores by means of the at least one drill (10, 13, 14).

A gas meter index repair apparatus with method for removing the gas meter index that has suffered broken attachment screws during the replacement or AMI\AMR upgrade process.

Previously as this damage to the meter index occurred, the only alternatives available were to replace the gas meter or manually drill and tap the broken attachment screws which would allow a high risk of puncturing the gas meter case causing a rapid release of highly flammable and explosive gas. These alternatives would incur multiple premise visits with interrupting the flow of gas to the user.

The RK Jig Guide apparatus connects to the available gas meter index attachment screws and aligns itself with the damaged index cover attachment screws offering perfect alignment to mechanically remove the broken attachment screws allowing their replacement without interrupting the flow of gas to the end user or creating a safety hazard.

This apparatus can be adapted and utilized for most residential gas meter installations. The RK Jig Guide apparatus includes a mounting assembly plate, various index mounting screws, complete detailed written instructions as well as companion video.

The RK Jig Guide is very user friendly and allows the entry level technician, such as a Meter Reader to successfully replace the meter index and cover on the first visit.
