Definitions

  • the object of the present invention is to provide a simple and inexpensive arrangement which is, nevertheless, reliable and effective and which will enable so-called tool bits or tool tips to be used without requiring expensive special-purpose devices herefor.
  • Figure 3 is an axial sectional view of the adapter and shows a tool bit inserted in the adapter.
  • the end-part 2 has the form of a circular collar which presents an opening 8 which diverges conically towards the front end-surface 7 of the sleeve 1.
  • the reference number 9 designates generally a tool bit which has a head or front end 10 of cruciform section and a rear ⁇ wardly located part 11 of polygonal cross-sectional shape.
  • the end-part 3 of the sleeve 1 is first inserted into the chuck 12, preferably until either the end-part 3 or the screw 5 comes into abutment with the bottom of the chuck bore or the rearwardly located side of the collar- shaped end-part comes into contact with the forwardly located end-surfaces of respective chuck jaws.
  • the tool bit 9 is inserted into the sleeve until its rear end-surface abuts the head of the setting screw 5, whereafter the chuck 12 is tightened so as to grip the sleeve 1 firmly in the chuck and to clamp the tool bit 9 firmly in the sleeve by contracting the slotted part thereof.
  • the adapter is illustrated in Figure 4, in which the reference number 14 designates part of a wall panel, e.g. a plasterboard, the reference 15 designates a lightmetal profiled stud or battern, and the reference 16 designates a so-called plastboard screw having a cross- grooved or Phillips screw-head.
  • the screw 16 is placed on the forward end 10 of the tool bit, which end has a cruciform section or Phillips configuration, and is pressed against the location at which the screw is to be driven with the aid of the drive device 13 during activation of said device.
  • the screw 16 is shown in full lines in Figure 4 partially inserted into the plaster ⁇ board 14, and in ghost lines fully inserted therein.
  • the tool bit will continue to drive in the screw 16, until the tool bit of cruciform section cams out of driving engagement with the cross-slotted screw head of the screw 16.
  • the setting screw 5 is adjusted to a setting at which this will occur immediately the screw 16 has been driven to the depth required.
  • the sleeve 1 may have a round external surface, and the forward end-part 2 of the sleeve 1 may have a permanent magnet fitted thereto, for detachably holding a screw placed on the screw driving end 10 of the tool bit 9.
