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： 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.

摘要： A hole saw assembly is revealed. The hole saw assembly is a hole saw with a quick change drill rod. The hole saw assembly includes a quick release device and the drill rod, both arranged at the hole saw. The drill rod is inserted through the quick release device and the quick release device is for fastening and releasing a drill head of the drill rod. Thereby the drill rod is fitted over the quick release device and users can fasten and release the drill rod quickly. Users can also quickly mount a shank of the drill rod quickly into the hole saw. The drill rod is fast slid out of the quick release device for replacement of a new drill rod. Then the shank is locked on the hole saw so that the shank and the hole saw can rotate synchronously.
