A pocket hole jig tool system includes a base on which a workpiece is supported. A drill guide support is slidably mounted to the base. Drill guide bushings are movably mounted relative to the drill guide support for clampingly engaging the workpiece and for guiding a drill for engaging the workpiece. A stop collar assembly is adjustably mounted relative to the drill guide bushings to automatically ensure a proper pocket hole location and depth for the workpiece inserted in the tool system.

A device for the temporary fixation of a portable cutting machine to a template for making holes and/or recesses in a workpiece including a guide sleeve and a tensioning unit. The guide sleeve includes a tubular hub with an outer diameter corresponding to an inner diameter of an aperture in the template, a forward end of the hub having radially extending lugs configured and located so as to match corresponding recesses in the aperture during the insertion of the guide sleeve therein and to obtain a locking engagement with an inner surface of the template after a partial rotation of the guide sleeve relative to the template. A rearward end of the hub has a tubular adapter socket that is mounted to a nose portion of the cutting machine. The tensioning unit is mounted to the adapter socket for axial displacement relative thereto and having a forward end surface for engagement with an outer surface of the template.

A drill stand (1) for a manually operable tool device (2) is formed of a fixedly mountable base plate (4) having a through passageway (5) extending perpendicularly therethrough for the passage of a clamping bolt (6) having at least one axially effective stop shoulder (7a, 7b), so that at least one detent means (8) with an axially effective counter shoulder (10a, 10b) for axial form-locking engagement of the shoulder stops (7a, 7b) of the clamping bolt (6). At least one manually operable eccentric cam (11a, 11b) affords axial clamping of the clamping bolt (6) locked by the detent means (8) and arranged relative to the through passageway (5).

A method of and apparatus for forming a through bore or recess in a turbine blade, for a lacing wire hole for example, includes a machine capable of approaching the area to be machined in a first direction during which an initial machining operation may take place and them moving in a second direction completing the machining operation. Support means are provided to ensure the blade is held firmly. The method and apparatus permit of accurate machining of blades when they are in an array of blades still secured to the rotor.

A tapping machine has a base plate fixed to one of the platens, a spindle extending along a spindle axis between the platens in the closing direction of the press actuating the machine, and a nut threaded on the spindle. The nut is normally rotatable about the spindle axis on the base plate and the spindle is fixed nonrotatably about the spindle axis on the other platen so that relative displacement of the platens rotates the nut in the base plate. An element displaceable on the base plate along an element axis but nonrotatable on the base plate about the element axis carries a plurality of tap holders generally fixed relative to the element axis in the element and rotatable in the element about respective tap axes parallel to the element axis. Respective taps are fixed axially and rotationally in the holders. A rotary transmission is provided that operatively connects the rotary nut and the holders for synchronously rotating the holders and their taps at a predetermined tap rotation rate about the tap axes on rotation of the nut about the spindle axis. An addition an axial-feed transmission connects the rotary nut and the element for synchronously axially advancing the element with the taps and tap holders on displacement of the platens from the outer position to the inner position through a predetermined tap stroke equal to a fraction of the press stroke and at a rate such that the taps are rotated through substantially only one revolution while being advanced through a distance equal to the pitch.

A drilling machine for drilling a stack of paper, comprises a first movable member moving along directions to press the stack of paper and to remote from the stack of paper and elastically supporting a pressing plate, a second movable member supporting a drilling mechanism and moving along the directions, and a control device for causing first and second driving mechanisms simultaneously to drive the first and second movable members respectively in the direction to release the stack of paper from compression and to separate the drilling mechanism from the stack of paper, whereby the stack of drilled paper is released from compression and the drilling mechanism is separated from the stack of drilled paper.
