Machine tool

A machine tool, comprising:

• a housing (1) having a center of gravity, a tool part (2) supported in said housing (1) and adapted to be driven by an energy source external to said housing, said housing including an abutment part (7) disposed opposite said tool part, whereby a workpiece can be introduced between said tool part and said abutment part,
• means for suspending said housing from a support structure, said means comprising a first rotary bearing (21) having an axis of rotation (VI) extending substantially through the center of gravity of said housing, said first rotary bearing being connected to a first end of a support arm (17),
• a second rotary bearing (23) disposed on said housing, said second rotary bearing having an axis of rotation (V) extending substantially through the center of gravity of the housing and disposed at an angle to the axis of rotation of said first rotary bearing, said second rotary bearing including a cuff fixed to a second end of said support arm,
• a first handle (24) mounted on said housing for adjusting the position of said housing about the axis of rotation of said second rotary bearing,
• a second handle (16) mounted on said cuff for adjusting the position of said housing about the axis of rotation of said first rotary bearing, and
• means (14) for delivering energy to said tool part extending inside said second rotary bearing.
