A depth limiting device includes a braking structure; a limited shrinking structure, the limited shrinking structure including a part that surrounds a moving object and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The braking structure brakes the moving object such that the moving object moves together with the depth limiting device. When the moving object enters into a subject, the part of the limited shrinking structure is pressed against the subject, and the limited shrinking structure moves from the home position to the compressed position and stops the moving object from entering further into the subject.

A cutting tool having a shank and a cutting head, wherein the shank carries a depth stop, which limits penetration depth into a workpiece, via at least one pivot bearing, and the depth stop is spring-preloaded away from the cutting head, via the at least one pivot bearing, against a shank-side stop.

A depth limiting device includes an axial braking structure; a limited shrinking structure, the limited shrinking structure surrounding a moving object, and being in a home position or a compressed position; and a structure adapted for pushing the limited shrinking structure to the home position. The axial braking structure axially brakes the moving object such that the moving object moves together with the depth limiting device, and when the moving object enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the moving object from entering further into the subject.

The invention relates to a drill hold assembly and a jig including the same. The drill hold assembly includes an engaging means which is selectively moveable between a released position to allow sliding movement of the drill bit with respect thereto and an engaged position in which the drill bit is held in a fixed position or within a predefined range of movement with respect to the engaging block to thereby maintain the drill bit in location with the drill hold assembly. The jig apparatus can be used with a powered drill to rotate the drill bit to provide a driving force to the drill bit and the jig is attached to a support surface and a workpiece is positioned between first and second jaws of the jig and the drill bit is advanced along a guide and introduced into the workpiece to form a hole therein at a predefined angle. The drill bit can then be removed from the hole and the drill bit is held by the drill hold assembly to retain the drill bit in a fixed position with respect to the jig to thereby allow relative movement of the jig apparatus and workpiece whilst the drill bit is retained in position with the jig apparatus.

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.

A depth limiting device for a drill includes a main body, an axial braking structure, and a limited shrinking structure. The axial braking structure is attached to the main body. The limited shrinking structure surrounds a drill rod of the drill, is slidably attached to the main body, and is in a home position or a compressed position. The axial braking structure axially brakes the drill rod such that the drill rod moves together with the depth limiting device. When the drill rod enters into a subject, the limited shrinking structure is pressed against the subject, moves from the home position to the compressed position, and stops the drill rod from entering further into the subject.
