A drilling device comprising a driving rotary drill and a bending moment loading means whose tensile side is the side of the drill head contacting surface of the plate material to be drilled. 2. The bending moment loading means includes a ring-shaped support that allows the drill to penetrate, which is arranged on the back side of the plate material where the drill abuts, and a ring-shaped support that is arranged approximately concentrically with the shaft of the drill and the ring-shaped support on the drill abutment side. 2. The drilling device according to claim 1, comprising: a ring-shaped pressing tool having an inner diameter larger than an outer diameter of the ring-shaped support; and means for controlling the pressing of the ring-shaped pressing tool against the plate material. 3 The head of the drive rotary core drill is formed by integrating a tapered leading edge part and a cylindrical trailing blade part, and the grain size of the abrasive grains implanted on the outer periphery of each is 100 mesh or more at the leading edge part. A core drill characterized in that the trailing cutting edge has a mesh size of 200 meshes or less. 4. The drilling device and core drill according to claims 1, 2, and 3, comprising a driving rotating core drill and a bending moment loading means whose tensile side is the surface of the plate to be drilled that is in contact with the core drill head.
