Abstract

Ein Bohr- und/oder Meisselwerkzeug (1) umfasst einen Schaft (2) und ein mit dem Schaft (2) verbundenes, zylindrisches Einsteckende (4) mit wenigstens einer, zur Aussenkontur und zum freien Ende (9) des Einsteckendes (4) hin offen ausgebildeten, länglichen Ausnehmung (5 - 8). Zwischen dem Schaft (2) und dem Einsteckende (4) ist ein Bund (3) angeordnet, der sich wenigstens teilweise um das Werkzeug (1) herum erstreckt und den Schaft (2) sowie das Einsteckende (4) wenigstens bereichsweise radial überragt. Das zylindrische Einsteckende (4) weist einen Durchmesser auf der gleich oder grösser 18 mm, vorzugsweise grösser 22 mm ist. Die wenigstens eine Ausnehmung (5 - 8) besitzt eine sich senkrecht zur Mittellängsachse des Werkzeuges (1) erstreckende und zur Aussenkontur hin erweiternde, im wesentlichen teilkreisförmig ausgebildete Querschnittsfläche. Es ist auch eine auf das Einsteckende abgestimmte Werkzeugaufnahme eines Bohr- und/oder Meisselgeräts beschrieben.

Figure 00000001
A drilling and / or chiseling tool (1) comprises a shaft (2) and a cylindrical insertion end (4) connected to the shaft (2) with at least one towards the outer contour and towards the free end (9) of the insertion end (4) open, elongated recess (5 - 8). A collar (3) is arranged between the shaft (2) and the insertion end (4), which extends at least partially around the tool (1) and projects radially beyond the shaft (2) and the insertion end (4) at least in regions. The cylindrical insertion end (4) has a diameter which is equal to or greater than 18 mm, preferably greater than 22 mm. The at least one recess (5-8) has a cross-sectional area that is essentially part-circular and extends perpendicular to the central longitudinal axis of the tool (1) and widens towards the outer contour. A tool holder of a drilling and / or chiseling device that is matched to the insertion end is also described.
