Abstract
PURPOSE:To surely collect cutting dust by a method wherein a supply fan is rotated in connection with the spindle of a driving motor so as to supply air from a suction port to an exhaust port, both of which are formed on a casing, in order to exhaust the cutting dust, which is collected by a dust collecting mechanism at the suction port, through a dust communicating path. CONSTITUTION:A diamond tip 13 bores concrete through the rotation of the spindle 3 of a driving motor 1. In addition, a supply fan 20 is also rotated integrally with the spindle so as to generate air flow, which runs from a suction port 17 to an exhaust port 18, in a dust carrying path 19. The front surface of the main body part 23 of a dust collecting mechanism 22 abuts against a concrete wall 35. As boring proceeds, the rear end part of a bar part 25 advances in the recesses of a guide pipe 27. Cutting dust enters the opening 30 of the main body part 23 without scattering around, passes through a hollow part 25a and the dust carrying path 19 and finally is exhausted from the exhaust port 18 of a casing 2.
