Abstract

A tool (1) has a distal operative portion and a proximal shank (2) with a mounting portion (3), for mounting the tool in a holder (10). A substancial portion of the mounting portion has a cross-sectional shape with at least one and fewer than six 60-degree segments thereof having segment ends joined by a flat surface (5). The holder has a distal axial aperture or mounting hole (12) for receiving the tool (1), the aperture having a cross-sectional shape which has 60-degree segments thereof having segment ends joined by a flat surface (13), but no more such flat surface segments than those corresponding to flat surface segments of the tool. The holder further has a ball-detent (21) mechanism or other locking mechanism for engaging the mounting portion (3) of the tool (1).

Claims (14)

1. A tool having a distal operative portion and a proximal shank with a mounting portion for mounting said tool in a holder of a tool driver via an axial aperture in the holder, characterized by a length of said mounting portion having a cross-sectional shape with at least one and fewer than six 60-degree segments thereof having segment ends joined by a non-circular surface, adapted for engagement in said aperture when said aperture has a cross-sectional shape which has at least one 60-degree segment thereof having segment ends joined by a non-circular surface, corresponding to at least one said non-circular surface of said mounting portion, and no more such non-circular surface segments than those corresponding to said non-circular surface segments of said tool.
2. A tool as recited in claim 1, wherein there are two said 60-degree segments having segment ends joined by a flat surface, said two segments being on opposite sides of said mounting portion from each other.
3. A tool as recited in claim 1, further characterized by a portion of said mounting portion has a circumferential groove extending at least partway around the mounting portion's circumference, adapted to receive locking means of said holder.
4. A tool having a distal operative portion and a proximal shank with a mounting portion for mounting said tool in a holder of a tool driver via an axial aperture in the holder, characterized by a length of said mounting portion having a cross-sectional shape with at least one protrusion therefrom, adapted for engagement in at least one slot in aperture of said holder.
5. A tool having a distal operative portion and a proximal shank with a mounting portion for mounting said tool in a holder of a tool driver via an axial aperture in the holder, characterized by a length of said mounting portion having a cross-sectional shape with at least one slot therein, adapted for engagement with at least one radially-inward protrusion in said aperture.
6. A tool as recited in claim 1, wherein said mounting portion is generally triangular in cross-section along a major portion of the shank.
7. A tool as recited in claim 6, wherein surfaces defining said generally triangular shape are bulged outwardly somewhat, rather than being linear as in a pure triangle.
8. A tool as recited in claim 1, wherein said mounting portion is generally square in cross-section along a major portion of the shank.
9. A combination of a tool and a tool-driver having a holder with a distal axial aperture for receiving said tool, said tool having a distal operative portion and proximal shank with a mounting portion, for mounting said tool in said holder, a substantial portion of said mounting portion having a cross-sectional shape with at least two segments thereof having segment ends joined by a non-circular surface, said aperture having a cross-sectional shape which has at least two segments thereof having segment ends joined by a corresponding non-circular, but no more such non-circular surface segments than those corresponding to non-circular surface segments of said tool, and including locking means for engaging said mounting portion, said at least two segments corresponding to an angle of between 60 and 120 degrees of said aperture.
10. A combination as recited in claim 9, wherein said non-circular surfaces are flat.
11. A combination as recited in claim 9, wherein said cross-sectional shape of said aperture has two opposing flat 60-degree segments, the other said segments being circular, thereby defining a somewhat ovaloid shape capable of receiving said tool bits having a variety of cross-sectional shapes, including hexagonal, triangular, and said ovaloid shape.
12. A combination as recited in claim 9, wherein said locking means comprises manually operated engagement means for locking said mounting portion in said holder, for manually engaging said engagement means in locking position after insertion of a tool in said holder.
13. A combination as recited in claim 9, wherein said locking means comprises engagement means which automatically lock said mounting portion in said holder, upon insertion of a tool in said holder.
14. A combination as recited in claim 9, wherein said locking means comprises a locking ball mechanism.
