Abstract: A tool bit for a chisel or a hammer drill, in particular, a insertable chisel or insertable drill for power-driven drill and chisel hammers, has an insertion end, with a chisel shank or drill shank, and a chisel head or drill shank located opposite the insertion end. The diameter of the shank increases in the direction of the chisel head at least once from a first, small diameter to a second, large diameter and decreases again from this to a small diameter or forms at least one bead.

Abstract: A multimedia message service center and telecommunication device for accessing deposited multimedia messages. The forwarding and receipt of multimedia messages transmitted in networks that are configured for the Multimedia Messaging Service (MMS) independent of the communication between the networks and the infrastructure and the topology of the respective network from any transmitter to any addressee. A dial-in information (EWI) is indirectly or directly sent to the telecommunication device in addition to a communication message (MN) sent indirectly or directly e.g. via a short message center and/or an additional multimedia message center to the telecommunication device (ETKG) in response to a multimedia message (MMN) destined for a telecommunication device (ETKG) and deposited in the multimedia message center (MMNDZ). This dial-in information (EWI) tells the telecommunication device where to dial in to be able to access the multimedia message (MMN) addressed to the telecommunication device.

Abstract: The invention relates to a flat chisel, in particular an insertion chisel for power-driven drill and chisel hammers for working stone, having a chisel head which has a main tip disposed transversely to a chisel longitudinal axis, a front and rear striking surface, and at least one side face connecting the striking faces. In this case, a side face designed as a side lip is provided.

Abstract: The invention relates to a drilling tool (36), in particular for working concrete, rock, masonry and suchlike materials, having a single- or multi-edge tool head with at least one cutting body (1) which comprises a central region (12) which is designed in a roof shape, has rake faces and flanks and is defined laterally by two outer regions (13, 14) set back in the effective direction of the drill. In this case, the ground surfaces of the central region (12) form a pyramidal point (15) while avoiding the formation of a chisel edge.

Abstract: The invention relates to a drilling tool (1), in particular for working concrete, rock, masonry and suchlike materials, having a tool head with cutting body (5) which has at least one front rake face (9, 10), at least one rear flank ([lacuna] 18) and at least one front-end cutting edge (7, 8), the cutting edge (7, 8) separating the rake face (9, 10) and the flank ([lacuna] 18). In this case, the rake face (9, 10) is formed by at least two cutting faces (11, 13; 12 [lacuna]) merging into one another at at least one second cutting edge (15, 16).

Abstract: The invention relates to a flat chisel (2), in particular an insertion chisel for power-driven rotary hammers for working stone, having a chisel head (3) which has a main lip (7) disposed transversely to a chisel longitudinal axis (x), a front and a rear striking face (10, 11), and at least one side face (12, 13) connecting the striking faces (10, 11). In this case, a side face (12, 13) designed as a side lip (14, 15) is provided.

In this case, an approximately concave and/or convex and/or bent and/or undulating profile of at least one lip (7, 14, 15) is provided.

Abstract: The invention relates to a method for the production of a tool, in particular a drill (6) or milling cutter, having at least one conveying helix (8a, 8b), proceeding from a bar-shaped blank (1). In this case, there is provision for introducing the conveying helix (8a, 8b) in a single operation by means of a machine tool, the blank (1) having a diameter (DR) which is larger than a diameter (dF) of the conveying helix (8a, 8b).

Abstract: The invention relates to a chisel (1) or a hammer drill, in particular insertable chisel or insertable drill for power-driven drill and chisel hammers, with an insertion end (2), with a chisel shank (3) or drill shank and with a chisel head (4) or drill shank located opposite the insertion end (2). In this case, the diameter of the shank (3) increases in the direction of the chisel head (4) at least once from a first, small diameter to a second, large diameter and decreases again from this to a small diameter or forms at least one bead (8).
