Tool system that can be coupled to a lathe drive shaft

A tool system that can be coupled to the drive shaft of a rotary tool, such as a hand drill or a screw drill comprising:

• a) a tool holding fixture coupled to the drive shaft of the rotary tool said tool holding fixture having a reception cylinder which contains a polygonal recess and wherein said reception cylinder contains a centering range;
• b) a combination tool disposed in said polygonal recess, of said reception cylinder said tool being fixed to said reception cylinder rotation fast, wherein said tool has a plurality of shafts extending coaxially within said polygonal recess, wherein said plurality of shafts each have at least one detent recess and at least one centering section which fit into, and contact said centering range on said tool holding fixture when in operation, and at least one functional section coupled to and extending coaxially with said shafts and wherein said plurality of shafts each have connection sections having undercuts;
• c) a plastic coupling ring having round bulges for engaging into said undercuts of said connection sections;
• d) a locking sleeve disposed around said tool holding fixture, and axially movable around said holding fixture;
• and
• f) at least one detent element, said at least one detent element disposed within said tool holding fixture, and for engaging said at least one detent recess of at least one of said plurality of shafts, wherein said locking sleeve can be moved along said tool holding fixture to alternately move said at least one detent element into a locking arrangement with said detent recess or an unlocking arrangement removed from said detent recess so that said tool can be either locked in or unlocked from said tool holding fixture.

A tool system that can be coupled to the drive shaft of a rotary tool, such as a hand drill or a screw drill comprising:

• a) a tool holding fixture coupled to the drive shaft of the rotary tool, said tool holding fixture having a reception cylinder, which includes:
• i) a polygonal recess;
• ii) a centering range;
• iii) a torsion zone;
• and
• iv) a bending zone, wherein said torsion zone and said bending zone being disposed between radial recesses providing the reception of said at least one detent element and the centering range of said polygonal recess;
• b) a combination tool comprising a plurality of tools being disposed in and fixed rotation fast to said polygonal recess of said reception cylinder, wherein each of said plurality of tools has a shaft and further includes:
• i) a centering section disposed within said shaft that fits into and contacts said centering range, wherein said centering section includes at least one detent recess disposed on said shaft;
• ii) at least one functional section comprising at least one sink section disposed on said shaft which can bevel drill holes for containing a threaded hole, and wherein at least one tool of said plurality of tools includes said functional section having a tap drill which is adapted to a cross section of the drill,
• a locking sleeve disposed around said tool holding fixture, and axially movable around said holding fixture;
• and
• at least one detent element disposed within said tool holding fixture, and for engaging said at least one detent recess of said tool shaft, wherein said locking sleeve can be moved along said tool holding fixture to alternately move said at least one detent element into a locking arrangement with said detent recess or an unlocking arrangement removed from said detent recess so that said tool can be either locked in or unlocked from said tool holding fixture.

A tool system that can be coupled to the drive shaft of a rotary tool, such as a hand drill or a screw drill comprising:

• a) a tool holding fixture coupled to the drive shaft of the rotary tool, said tool holding fixture having a reception cylinder, which contains a polygonal recess and wherein said reception cylinder contains a centering range;
• b) a tool disposed in said polygonal recess, of said reception cylinder, said tool being fixed to said reception cylinder rotation fast, wherein said tool has a shaft adapted to fit into said polygonal recess, wherein said shaft has at least one detent recess, at least one functional section, and at least one centering section which fits into and contacts said centering range on said tool holding fixture when in operation,
• c) a locking sleeve disposed around said tool holding fixture, and axially movable around said holding fixture;
• d) at least one detent element disposed within said tool holding fixture, and for engaging said at least one detent recess of said tool shaft, wherein said locking sleeve can be moved along said tool holding fixture to alternately move said at least one detent element into a locking arrangement with said detent recess or an unlocking arrangement removed from said detent recess so that said tool can be either locked in or unlocked from said tool holding fixture;
• e) a depth abutment which can be releasably mounted on said tool holding fixture, said depth abutment having a rearward section on said reception cylinder, and a forward section which is rotatably journalled at said rearward section;
• and
• f) a lock coupled to said depth abutment wherein said lock extends into, and is releasably connectable to a corresponding detent recess of said reception cylinder.
