Provided is a cutting device that prevents a variation of shocks or impacts applied to a substrate during a cutting operation. The cutting device includes a pressing part; a cutting part disposed so as to move with respect to the pressing part so as to contact the substrate on an opposite side of the pressing part to thereby sandwich the substrate between the cutting part and the pressing part to shear the substrate; a first force generation part for generating pressing force to press the pressing part against the substrate; and a first adjustment part for adjusting the pressing force in response to the force applied from the substrate to the pressing part when the pressing part presses the substrate with the first force generation part.

A wishbone separator device for separating a wishbone from a poultry carcass includes a primary wishbone cutter including a front cutter portion including a central front apex, a left and a right front cutting edge, which diverge from said central front apex, a wishbone limb cutter portion, including a left and a right limb cutting edge. An intersection point of an extension of the left limb cutting edge and an extension of the right limb cutting edge is arranged on a center line parallel to the cutting direction through the central front apex. The left and right front cutting edge are arranged forward of the left and right limb cutting edge, respectively as seen in the cutting direction and outward relative to said imaginary extension line from the left and right limb cutting edge, respectively.

Disclosed is an oscillatingly driven machine tool including a tool spindle that is mounted pivotably about its longitudinal axis, further including a drive motor that is coupled to a hydraulic generator for generating an oscillating fluid flow which drives a hydraulic motor being configured as a rotor blade motor. The rotor blade motor drives the tool spindle in such a way that the tool spindle rotates oscillatingly about its longitudinal axis. The rotor blade motor includes symmetrically arranged rotor blades that are disposed at regular angular distances with respect to each other.

A hole punching machine for use on wet or damp drywall improves ventilation behind the drywall for drying purposes. The machine includes a base position on the floor and against the wall. A pneumatic ram in the base can be extended and retracted to cut a hole in drywall, after any baseboard is removed. The hole can then be covered when the baseboard is reinstalled. The operator can activate the ram using a switch, while standing.
