A system, method, and apparatus for the rigid alignment of drill bits (23) with ergonomic drill motors (13,17) is disclosed. An adjustable nosepiece adapter (41) is mounted to the ergonomic drill motor adjacent the drill bit chuck (21). The adapter (41) has a split clamp portion (45) on its distal end for receiving a pressure foot (61). A guide bushing (71) fits in the proximal end of the pressure foot (61). A coil spring (65) is located in the pressure foot (61) and allows the guide bushing (71) to telescope within the pressure foot (61). The drill bit (23) extends through the guide bushing (71), pressure foot (61), and adapter (41) and is secured to the chuck (21). The distal end of the guide bushing (71) fits closely within a hole (83) in a template (81) that is secured to the workpiece (91) to provide holes that are more accurately formed in the workpiece (91).

A drill bit has a shank portion having a plurality of SDS-type slots, a cutting portion comprising at least one cutting flute, and an intermediate portion connecting the shank to the cutting portion, the intermediate portion including at least one additional slot. A depth gauge includes a body configured to receive the drill bit, a retention mechanism coupled to the body and having an inward projection to removably couple the body to the at least one additional slot in the drill bit, and a cap coupled to the body such that the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a predetermined depth, wherein the cap is movable relative to the body among a plurality of positions, wherein each of the plurality of positions corresponds to a different predetermined drilling depth.

A hydraulic stop (2) for use in drilling or countersinking operations comprising a rotatable body for rotating a tool (6) about its axis and a cage (20) adapted to contact the surface of a workpiece (8) when the tool has penetrated into the workpiece by a predetermined distance and to actuate a trip mechanism comprising a plungeroperated hydraulic valve (30, 32) as the tool (6) penetrates the workpiece more than the predetermined distance, wherein the plunger (28) is of adjustable length. When actuated the trip mechanism allows the body to shrink in length suddenly. The cage (20) is axially adjustable in relation to the body to set the predetermined depth at which the trip mechanism actuates. Drainage means is provided comprising a plurality of holes spaced around the circumference of the body to which the cage (20) is mounted to allow drainage of coolant whatever the axial position of the cage (20).

The invention relates to a machine tool for creating boreholes in a workpiece (22), said machine tool comprising a machine frame, a boring tool holder (36) which is arranged on the machine frame (12) and has at least one tool spindle (34), and a workpiece carrier (18) which is arranged on the machine frame, the boring tool holder (36) and the workpiece carrier being displaceable in relation to each other in a direction of displacement X. The aim of the invention is to develop one such machine tool in such a way that it can be easily produced and operated in an advantageous manner. To this end, a longitudinal direction (38) of the at least one tool spindle is oriented transversally in relation to a horizontal plane, and the boring tool holder is arranged on the machine frame in such a way that it can be pivoted in relation to the workpiece carrier, such that inclined boreholes can be created in the workpiece.

A drill press includes a vertically disposed support post and a pivot assembly supported upon the support post. A table is supported on the pivot assembly. The pivot assembly is pivotable about a first substantially horizontal axis, with the table pivoting about the first horizontal axis jointly with the pivot assembly. The table also is pivotable relative to the pivot assembly about a second substantially horizontal axis. The pivot assembly also may be pivoted around a vertical axis defined by the post and may be raised and lowered along the vertical post.. A clamp plate is adjustably secured to the table and a telescoping extension arm is fixably secured relative to the table by the clamp plate. A guide fence is slidably disposable along the upper surface of the table and may be secured at various locations. A clamp may be adjustably secured either directly to the table or to the guide fence to vertically clamp a workpiece on the table. The table also includes an opening and an inner table which is removably disposable and supported within the opening. A router may be removably secured to the lower surface of the table, with the router bit disposed generally beneath the drill chuck.

The invention relates to a method and an apparatus for making an elongated hole in a pipe (P) by means of a rotating conical drill (1). The elongation of a hole is accomplished such that, during the course of drilling, the conical drill is manoeuvered simultaneously in the longitudinal and tranverse direction of the pipe, the transverse movement being effected away from or towards the centre axis. This combined movement is accomplished by tilting the conical drill while simultaneously lifting the drill out of the pipe. Alternatively, the drilling can be commenced from the end of a hole, progressing towards the centre of a hole while increasing the drilling depth.

The invention relates to an exchangeable needle cartridge (10) for a drilling measuring device (1), to the drilling measuring device (1) itself, and to an exchangeable docking device and the associated tool. The exchangeable needle cartridge (10) has a guiding device for a drilling needle (13), which guiding device is designed as a telescopic tube (12) having a plurality of telescopic tube sections (12'). The plurality of telescopic tube sections (12') extends between a working end, at which a retainer (14) for retaining the drilling needle (13) in a rotationally fixed manner is arranged, and a docking end, at which a docking device (15) for coupling the telescopic tube (12) to a driving device of the drilling measuring device (1) is arranged. The docking device (15) comprises a coupling device (16) for transmitting torque from the driving device of the drilling resistance measuring device (1) to the telescopic tube (12), a transmission device for converting the rotational motion of the driving device of the drilling measuring device (1) into a linear motion of the telescopic tube (12), and furthermore means for detachably fastening the exchangeable needle cartridge (10) to the drilling measuring device (1).
