A drilling system configured to install a tap assembly into a ship skin is disclosed. The drilling system comprises a remotely-operated underwater vehicle and a drilling assembly configured to be operated by the remotely-operated underwater vehicle. The drilling assembly comprises a frame comprising an attachment element configured to hold the drilling assembly to a surface of the ship skin. The drilling assembly further comprises a drill actuation system comprising a linear actuator attached to the frame and a rotary actuator, wherein an actuation of the linear actuator is configured to move the rotary actuator relative to the frame to install the tap assembly into the ship skin by driving the tap assembly with the rotary actuator and the linear actuator.

A drill press has a main housing, a drill unit supported by the main housing for relative movement therewith, and a base coupled to the main housing, the base includes a magnet assembly to create a magnetic field for magnetically latching the base to a workpiece. The magnet assembly is rotatably attached to the base and includes a shaft and at least one permanent magnet disposed on the shaft. The shaft is rotatable between a first position where the base would not magnetically engage the workpiece and a second position where the base would engage the workpiece. An auxiliary handle is pivotably attached to the main housing and movable from a first handle position preventing removal of a power tool battery pack from the main housing and a second handle position allowing removal of the power tool battery pack from the main housing.

A drill press includes a main housing, a base coupled to the main housing and having an electromagnet, a drill unit supported by the main housing for relative movement therewith, a first switch selectively electrically connecting the electromagnet to a power source to energize the electromagnet, and a second switch for selectively interrupting power to the electromagnet.

A vise for securing a work piece is disclosed which includes a base. A first jaw piece and a second jaw piece can be disposed on the base, at least one of the first and second jaw pieces movable on the base such that the first and second jaw pieces are moveable toward and away from one another. A magnetic assembly can be positioned on the base and configured to produce a magnetic field that extends beyond the base to secure the vise to a magnetically permeable or ferromagnetic work surface. The magnetic assembly can be operable to alternate between an active mode and an inactive mode. The magnetic assembly can produce a magnetic field when the magnetic assembly is in the active mode to secure the vise to a magnetically permeable or ferromagnetic work surface.

A magnetic base for supporting a tool having a work piece engagement component relative to a ferromagnetic body, comprising: at least two magnet units having a working face, each unit adapted to be magnetically attached to the ferromagnetic body; and a support structure coupled to the at least two magnet units and including a mounting structure adapted to secure the tool to the support structure, the support structure having a window in or a cut-out extending into an about centric location of the support structure such that the work piece engagement component of the tool may extend from a first side of the support structure to engage the ferromagnetic body located proximate a second side of the support structure, the second side being opposite the first side, the at least two magnet units being positionable so that they can fit onto a flat surface or a curved surface.

A drill press includes a main housing, a base coupled to the main housing, and a drill unit supported by the main housing for relative movement therewith. The base includes a bore formed in a top surface and a magnet to create a magnetic field for magnetically latching the base to a workpiece. The drill press further includes a holding force detection assembly having a plug and a sensor coupled to the plug to detect the magnetic field within the base. The holding force detection assembly is received within the bore formed in the top surface of the base.

A magnetic base for coupling a drill press to a ferromagnetic workpiece includes a ferromagnetic body having spaced, substantially parallel first and second rails. Each of the first and second rails includes a flat bottom surface engageable with the ferromagnetic workpiece. A coil is positioned between the first and second rails for generating a holding force on the ferromagnetic workpiece. The coil defines a central axis that is parallel with the bottom surface of each of the first and second rails.

A drilling machine, in particular a magnetic core drilling machine. The drilling machine having a magnetic base to detachably secure the drilling machine to a surface. A drive motor is arranged in a housing and has a rotor shaft with a rotor shaft longitudinal axis that is connected in a power-transmitting manner via a gear mechanism to a tool spindle with a spindle longitudinal axis. A tool holder is connected to the tool spindle to receive a drilling tool. The spindle longitudinal axis is aligned substantially parallel to the longitudinal axis of the rotor shaft, and the tool spindle is axially adjusted along the longitudinal axis of the spindle relative to the drive motor and the magnetic base.

Laser guides and methods of using the laser guides in conjunction with drilling equipment to accurately produce holes in workpieces. Such a laser guide includes a body, a laser source configured to generate a laser beam, a first end of the body configured to be releasably coupled to the spindle of the drilling machine, and a second end of the body configured to emit the laser beam such that the laser beam is axially aligned with an axis of rotation of the spindle of the drilling machine when the first end is coupled to the spindle.
