摘要： PROBLEM TO BE SOLVED: To provide a boring device which simultaneously bores a plurality of fitting holes etc. crosswise in a single row and at an optional pitch, in concrete flooring, and also precisely bore a plurality of fitting holes etc. crosswise in a single row, and at a longitudinal optional position with the same pitch by slidably moving the device horizontally as it is.
SOLUTION: A horizontal guide plate 1, to which a plurality of boring machine bodies 2 are fitted movably from right to left or vice versa, is installed on a support frame attached upright to the surface of a base plate 10 in the way that the horizontal guide plate 1 is ascendable by an ascending drive means 14. The horizontal guide plate 1 is installed ascendably by an ascending drive means 14. The base plate 10 is movable on a pair of right and left linear guide rails 21, extending in parallel, in the forward/backward direction, which is orthogonal with the horizontal guide plate 1 on a base frame 18, of a rectangular shape as viewed on the plane, which is immobilized on the upper surface of the concrete flooring.

摘要： PROBLEM TO BE SOLVED: To provide an excavating bit of a simple structure which can efficiently guide and suck cut powder to the inside of the excavating bit when the excavating bit is rotated without releasing the cut powder to the outside. SOLUTION: This excavating bit includes a plurality of outer peripheral tips 4 which are fixed to the bottom wall 3 of a cylindrical alloy at predetermined intervals in the circumferential direction, a plurality of intermediate tips 5 which are positioned between the outer peripheral tips and extend radially, a center tip 6 which is fixed at the space part on the radial inside of the intermediate tip, and a plurality of suction ports 9 drilled at the inner position of the outer peripheral tips. The radial outer surfaces 4A of the outer peripheral tips are positioned further on the outer side than the outer peripheral surface of the excavating bit 1, and the tip surface 4C of the excavating bit in the rotating direction is formed of an inwardly tilted surface.
