Tool system

Abstract

The invention relates to a tool system comprising an exchangeable rotary tool (1) for electric hand-held machine tools, preferably with a drill and / or hammer function, in particular for an electric hammer drill, and an electric drill, in particular a percussion drill. Said tool system also comprises at least two tool holders (15) that are embodied as tool fittings (17) that are associated with the hand-held machine tools and are different types (16, 22). The rotary tool (1) comprises an insertable shank (3) to be accommodated in the respective tool holder (15) of the hand-held machine tools, said shank having at least two driving fins (5) that are diametrically opposed and that extend along its longitudinal extension for rotational engagement. Said tool fitting (17) of a first type (16) is embodied as a positive fit fitting (18) and another tool fitting (17) of the second type (22) as a multi-jaw clamping chuck (23). The driving fins (5) have a width and a height such that, in the clamped state, they are at a lateral distance from the clamping jaws (24) of the multi-jaw clamping chuck (23).

Description

technical field [0001] The invention relates to a tool system with an exchangeable rotary tool for an electric hand-held power tool, preferably with a drilling and / or hammering function. Background technique [0002] Tool systems with exchangeable rotary tools for electric hand-held power tools are known. For example, there are tool systems for clamping in conventional three-jaw chucks, in which the rotary tool has an essentially cylindrical shank with a more or less circular cross section. For these rotary tools, the rotation of the tool is important. Furthermore, there are tool systems for which rotary motion is, on the contrary, less important than impact motion, as is the case, for example, with the SDS-Plus receiver. Here too, it is particularly desirable to be able to easily replace rotary tools (eg rock drill bits), for which reason the insert shank of the SDS-Plus drill bit has a special geometry. Furthermore, there are tool systems with a hexagonal cross-section,...

Problems solved by technology

All these tool systems have the common disadvantage that they are not always sufficiently compatible with other tool systems in the desired manner, that is to say that an insert tool or rotary tool can only be compatible with a corresponding one of the corresponding tool systems. Receiver connection, or restrictions when connecting to a tool receiver of another tool system

It is therefore not possible, for example, to clamp the SDS-Plus receiver in a three-jaw chuck, since the special geometry of the three jaws for SDS-Plus holders or other holders for quick-change systems on the market does not exist Possibility of Center Orientation
