    摘要： The invention relates to a core drill with an end portion (3) and a drill bit portion (1-2). The end portion and the drill bit portion are joinable in a watertight fashion with a sealing element (11). The sealing element (11) is provided in a space between the end portion and the drill bit portion, such that it is being compressed in a sealing fashion when the end portion and the drill bit portion are joined. The end portion and the drill bit portion are locked together with a joining element (8, 10) which achieves this locking effect when moves in the radial direction of the core drill. When the joining element moves in this direction, the end portion and the drill bit portion move towards each other. Thus the sealing element is being compressed while concurrently the end portion and the drill bit portion are joined together. This is further achieved without the joining element having to extend in the axial direction of the core drill. Typically, the joining element (8, 10) is constituted by a set screw.

    摘要： The invention relates to a control method for a core drilling machine and a feed device for driving the core drilling machine along a machine holding device, the method comprising the following steps: moving the core drilling machine in a first direction, detecting the surface position of a material based on reaching a threshold value for at least one feed device parameter as first reference value; moving the core drilling machine in a second direction; operating the core drilling machine in a tapping mode; moving the core drilling machine in the first direction; detecting the surface position of a material based on reaching a threshold value for at least one corresponding drill parameter as a second reference value; activating a water supply; and activating a regulating and control device for adapting at least one drill parameter subject to at least one parameter of the feed device. The invention further relates to a feed device for driving a core drilling machine along a machine holding device for use of the method, to a core drilling machine for use of the method, and to a core drilling system comprising a core drilling machine and a feed device for driving the core drilling machine along a machine holding device for use of the method.

    摘要： A support assembly for a core drill uses an improved reinforcement. The reinforcement can include an extension extending between a center of the tool and a perimeter of the tool the extension can be a non-planar structure having a channel along a portion of the structure. The reinforcement can include a slanted element that can be associated with the extension, that can be formed monolithic with the extension, or otherwise combined with an extension. Multiple slanted elements can be used to form an extension. A top plate can be included for strengthening the reinforcement.
