先を充分に冷却することができない。(Problems to be Solved by the Invention) Drilling a large number of small holes in a concrete wall using the above-mentioned twist drill creates intense noise. For this reason, the applicant of the present application developed and filed an application for a rotary drilling drill that can drill holes only by rotational motion without imparting vibration in the axial direction (Japanese Patent Application No. 59-28718). , These drills use sintered metal containing diamond powder for the cutting edge, and the cutting edge becomes hot due to intense friction with the concrete.For this reason, it is important to cool the cutting edge during drilling to extend its life. Although desirable, conventional drilling methods do not provide adequate cooling of the cutting edge of the drilling drill.
また、孔を穿孔すると切粉としてコンクリート粉が生じ

リート粉で汚染されることを防止できる。When hole B is drilled in concrete wall surface A in this way,
The cut portion 25 gradually advances into the hole B and is heated by intense friction with the concrete. However, the cutting portion 25 is forcibly cooled by compressed air jetting out from the slit 27. Therefore, it is possible to prevent the cutting portion 25 from becoming high temperature and prevent the cutting blade 28 from deteriorating. In addition, the compressed air ejected from the slit 27 cools the cutting part 25, passes through the hole B together with the concrete powder, is discharged to the concrete wall surface A, and flows into the recovery case 33. Concrete powder is sucked into a suction pipe 34, and a suction machine (not shown) K equipped with a filter mechanism
It will be collected. Therefore, it is possible to prevent the air around the work site from being contaminated with concrete powder.
