A method of installing cable through material, for example, concrete, wood, masonry, plastic steel, or the like comprising a drill bit with a distal end having a hollow tip with an attachment mechanism for receiving the cable. The drill bit is drilled through the material, and left in place while the cable is attached to the proximal end of the drill bit. There is no need to remove the drill bit from the aperture or material to attach the cable thereto. After attachment to the drill bit, the cable is inserted through the aperture with the drill bit and removed from the drill bit after it passes through the material so it can be attached to a receiver device.

A portable electrical assembly includes an electric motor, a power module, and an electric motor power cord. The electric motor power cord is placed within a cavity of a housing of the portable electrical assembly and is operatively connected to the electric motor at first end and to the power module at a second end. The electric motor power cord is configured to move in response to the movement of the electric motor without the creation of sharp bends along its length as the electric motor moves between all of its possible operating positions including an extended position and a resting position and a plurality of intermediate position between the extended and resting position.

The present invention is a portable and rechargeable drill system that allows a user to conveniently carry on the user's body and perform work. As a preferred and non-limiting example, the portable and rechargeable drill system is lightweight and is comprised of a drill handpiece, a battery-powered control device, and a securing member or mechanism for the drill handpiece. The drill system may further comprise a control device case or holder. The drill handpiece preferably comprises a first end, a second end, a drill bit-spindle and housing assembly, a drill bit locking mechanism, a motor and housing assembly, and a power cord.

A tool for flash-trimming and/or cleaning a component, comprising a shaft and a processing element mounted on the shaft such that it can be removed, the processing element being designed as a flexible cord and being received on the shaft such that, in an operational state, it bulges radially outwards in at least some sections as the rotational speed of the shaft increases; the invention also relates to a processing system along with this tool

A cutting tool includes a body portion having a bar shape extending from a first end to a second end, and a sensor unit arranged on a surface of the body portion. The surface of the body portion includes a first surface, a second surface, and a third surface. The sensor unit includes a first strain sensor arranged on any of the first surface, the second surface, and the third surface, a board module electrically connected to the first strain sensor, and a wireless communication unit mounted on the board module and transmitting a signal containing information on strain of the body portion detected by the first strain sensor to the outside. The board module includes a first portion arranged on the first surface, a second portion arranged on the second surface, and a connecting portion electrically connecting the first portion to the second portion.

Assemblies, apparatus, and methods are described for designing modulation tool holder assemblies and installations for modulation-assisted machining, and, in particular, for rotating machining applications that benefit from the sinusoidal modulation motion while cutting fluids are simultaneously applied through the tool. In addition, the design of rotating modulation tool holder assemblies and systems is described. In a tool holder assembly for modulation in a rotating spindle, the electric power and/or control signals are transferred from an external source to the modulation tool holder assembly installed in the rotating machine spindle. Similarly, the high-pressure cutting fluid is transferred from a stationary source to the rotating tool holder assembly for modulation.

A portable electrical assembly includes an electric motor, a power module, and an electric motor power cord. The electric motor power cord is placed within a cavity of a housing of the portable electrical assembly and is operatively connected to the electric motor at first end and to the power module at a second end. The electric motor power cord is configured to move in response to the movement of the electric motor without the creation of sharp bends along its length as the electric motor moves between all of its possible operating positions including an extended position and a resting position and a plurality of intermediate position between the extended and resting position.

A stationary machine tool for machining, in particular core drilling, comprising a tool stand with a first tool stand housing interior. A chip guidance system comprises a magnet, wherein the magnet is arranged in the first tool stand housing interior such that chips produced by a machining process and entering the first tool stand interior are deflected by the chip guidance system.
