• a holding device disposed in the forward end region and having a lateral insertion opening for a working tool in one side of the forward end region, the insertion opening having an opening axis intersecting the middle axis defining an obtuse angle between the opening axis and the middle axis in a rearward direction from the point of intersection of the said axes;
• and wherein
• the forward grip section of the grip part is curved at a radius of 145 mm to 175 mm toward a surface of the handpiece away from the insertion opening, defining an acute angle between the forward grip section and the rearward grip section between 10° and 28°, the obtuse angle is greater than 98° and less than 102°.
