A hand-held apparatus is for hole-making in an elongated body. The apparatus has a housing including a rotatable cutting tool arranged to be axially movable from a non-cutting position into a cutting position. The first end portion of the housing comprises a clamping device arranged to be adjusted from a first, inactive position into a second, active position, wherein the clamping device, in the active position, is arranged to hold the apparatus fixed to the elongated body. The apparatus further has a device for connecting to a driving means, for example a hand-held drill.

A punch set for use with a punch tool to punch material from a wall of an electrical box. The punch set has a punch with a cutting section, and a die defining a cavity that is configured to receive the cutting section. The cutting section may have an annular or circular portion and a plurality of keyway forming portions each extending radially from the annular or circular portion. The cutting section of the punch may be insertable into the cavity of the die in a single orientation. The die may have a protrusion receivable within a recess of the punch when the cutting section is received in the cavity. One of the die or punch may have an extension that is receivable in a single orientation within an opening in the other of the die or punch.

The invention relates to a robotic working line for the production of cutting bodies for prosthetic surgery instruments, in particular cutting bodies able to milling/cutting or otherwise carrying out tissue removal processes in preparation for, or in the context of, prosthetic surgery interventions, in this case in the orthopaedic field, such as acetabular cutters, patellar cutters, glenoid cutters, rasps, broaches or similar tools, starting from hollow untreated components having at least one external surface and one opposing internal surface. The invention also relates to a working method for the production of cutting bodies for prosthetic surgery instruments and to a cutting body made by means of a robotic working line and in accordance with the method according to the invention.

A punching mold device capable of rotating a workpiece includes an upper mold base, a lower mold base opposite to the lower mold base, an indexing rotation plate, a servo motor and a position-fixing element. The lower mold base includes a clamping portion for fixedly clamping a workpiece. The indexing rotation plate is formed with holes which collectively form a circular contour. The servo motor is connected to the indexing rotation plate and the workpiece, and synchronously rotates the indexing rotation plate and the workpiece. The position-fixing element includes a positioning pin which aims towards and is pluggably connected to one of the holes for stopping the rotation of the indexing rotation plate and the workpiece. The upper mold base includes a punching head module aligned with the clamping portion for punching the workpiece.

A slew-actuated stamping station includes an expandable core configured to apply radially outward pressure to a radially inward facing surface of a radial wall, and at least one slew-actuated punch for piercing, along a radially inward direction, a respective hole in the radial wall. A method for piercing a radial wall includes simultaneously (a) applying radially outward pressure against a radially inward facing surface of the radial wall, and (b) driving a slew to actuate at least one punch to pierce, along direction opposite the radially outward pressure, at least one hole in the radial wall. A method for forming an object, having a radial wall with holes, includes forming a ring with a radial wall, and piercing at least one hole in the radial wall with at least one slew-actuated punch.
