摘要： The tool for a tool holder of hand tools used for chiseling and/or percussion drilling has a chucking shank (9). This chucking shank (9) is provided with two rotary driving grooves (10) which are located diametrically opposite one another and open axially toward the free end of the chucking shank (9). Also, the chucking shank (9) has two diametrically opposite, axially closed locking grooves (11). In order to increase the total working surface decisive for the transmission of torque, two longitudinal grooves (12) are provided which are likewise arranged diametrically opposite one another and open axially toward the free end of the chucking shank (9). The length of these longitudinal grooves (12) exceeds the length of the locking grooves (11). The axes of symmetry (L) of the longitudinal grooves (12) are arranged at an acute angle (a) to the axes of symmetry (V) of the locking grooves (11). In addition, the flanks (12a) of the longitudinal grooves on the driving side extend in a straight line and tangentially relative to the base of the locking grooves (11) so as to form optimal working surfaces for the transmission of torque.

摘要： The clamping shank (1) of a chisel-cutting and/or percussion boring tool bits has stop faces effective in the axial direction and in the circumferential direction. Entrainment faces (2), open towards a free end of the clamping shank (1) are located upstream of these stop faces in the direction of the cutting area of the tool bits. The radial dimension (r) of the essentially radially extending entrainment faces (2) is greater than their axial dimension (a). In cooperation with an appropriately designed tool bit receptacle, the entrainment faces (2) can carry such a large share of the torque, that the stop faces are effectively relieved or unloaded.

摘要： A tool bit has an axially extending shank section (1) to be inserted into a chuck in a manually-operated tool. The tool bit has an axially extending working section extending from the shank section. In the end region of the shank section remote from the working section there are first faces (2) acting in the axial direction and second faces (3) acting in the circumferential direction. In addition, the shank section (1) has entrainment faces (4a) spaced axially from the first and second faces toward the working section. The entrainment faces (4a) are located radially outwardly from the first and second faces (2, 3). The entrainment faces (4a) are part of grooves formed by a profiled section of the shank section and the grooves are open in the axial direction toward the first and second faces. The entrainment faces (4a) are radially spaced outwardly from the outer surface of the part of the shank section containing the first and second faces, so that they are able to transmit larger torques.

摘要： The invention contemplates an improved drill-bit construction wherein the shank by which the bit is clamped is characterized by (a) three angularly spaced grooves which are continuous over their entire length of engageability to the jaws of a multi-jaw chuck, (b) at least one of the grooves being closed at its rear end, (c) the rear end of the closed-end groove is at no greater offset than 5-mm from the rear end of the bit, and (d) the diameter of the cutting part of the bit shank is greater than the diameter of the clamping part of the shank, to an extent which at most results from shaped formation of the chip-removal groove.
