Machining tool comprising a frame in which a drive shaft for a tool is mounted so as to pivot about a rotation axis and to move axially along the rotation axis. The shaft is connected to two rotary motors, namely a first motor connected to a member for meshing with a fluted portion of the shaft in order to drive the shaft in rotation and a second motor connected to a nut engaged with a threaded portion of the shaft in order to move the shaft axially. The motors are connected to at least one control unit designed to control the motors independently of one another, and the first motor and the second motor are coaxial with one another.

A position controlling device for a carpenter angle drill/hollow chisel mortiser has a mounting group, a positioning group, and a retaining arm. The mounting group has two crossbars and a bridge bar. The bridge bar is connected to the crossbars. The positioning group is connected to the mounting group, and has two limiting blocks, a holding frame, and a circuit breaker. The limiting blocks are connected to the bridge bar between the crossbars. The holding frame is securely connected to one of the limiting blocks. The circuit breaker is mounted in the holding frame and has a contacting slice and an electric wire. The contacting slice is elastically connected to the circuit breaker, and transversally extends out of the holding frame. The retaining arm selectively abuts the contacting slice of the circuit breaker to enable the circuit breaker at a turn-off condition.

A drill assembly attachment having a handle, a drill mount, and a throttle. The throttle may have a first portion and a second portion rotationally engaged with the first portion such that the second portion is rotationally actuated in response to linear actuation of the first portion of the throttle. The throttle is positioned with respect to the drill mount and the handle such that the first portion may be linearly actuated by a user with a hand grasping the handle. The drill assembly attachment receives a drill assembly such that the throttle adjustably engages a trigger of the drill assembly. The drill assembly attachment or the drill assembly receives an auger or other tool and the drill assembly attachment with the drill assembly and auger or other tool is used in a method of rotating the auger or other tool.

A drill press comprises a hollow pillar with a base, a holder for a drill slidably mounted on the pillar and a clamp integral to the pillar for clamping the base to a work piece so that the drill is guided to the work piece. The clamp is a G clamp with a jaw held by an arm which engages a screw thread shaft housed in the pillar so that rotating the shaft raises and lowers the arm and the jaw.

A method for performing operations on a structure. A moveable platform may be positioned in an area relative to the structure to define a working envelope. The moveable platform may be connected to a tool that may be moved around a plurality of axes within the working envelope using the moveable platform. The tool may be moved to a plurality of locations within the working envelope using the moveable platform. An operation may be performed with the tool through the working envelope at each of the plurality of locations using the moveable platform.
