Description of the Related Art Conventionally, pipes made of metal such as cast iron have been used for main pipes of water supply, but in recent years, polyethylene pipes have been used. When water is divided from the main pipe into each pipe, a water dip is attached to the polyethylene pipe, and a perforation tool is inserted from the upper opening of the water dip to perforate the polyethylene pipe. As punching tools therefor, there are those disclosed in Japanese Utility Model Laid-Open No. 6-28486 and Japanese Patent Laid-Open No. 11-277498.

される。In the device described in Japanese Utility Model Laid-Open No. 6-28486, the punching tool is formed in a circular tube shape, and the tip thereof forms a sharp cutting edge over the entire circumference. In the vicinity of the cutting edge, a plurality of through holes or holes are formed in the circumferential direction on the side wall of the punch, and a screw is formed on the outer circumference of the upper part thereof. Then, screw the punch into the cylindrical body of the branch pipe joint from above, cut the polyethylene pipe into a circle,
At that time, the section is received in the circular tube of the perforator, and is held in the perforator by using the through hole or the convex portion formed in the side wall. After that, the perforation tool is screwed in the opposite direction to the case of cutting, and the side wall is accommodated in the upper part of the water faucet while holding the section.
【０００４】しかし、この穿孔具は継手本体に取り付け

るという問題があった。However, there is a problem in that the perforation tool becomes a consumable item because it remains attached to the joint body and its cost is high.

落しないように保持される。Further, in the invention described in JP-A No. 11-277498, a circular tube-shaped Horso is provided with one or a plurality of cutting edges radially formed at the tip thereof and engraved on the inner circumference thereof. And a groove for discharging the cutting powder from the cutting edge. A cylindrical guide pipe surrounds the Horso. Unlike the punching tool of No. 6-28486, the cutting edge has a predetermined blade width and is formed like a cutting bite, so when drilling a polyethylene pipe, the outer circumference of the pipe is scraped. Powder is generated. Since the Horso is surrounded by the guide pipe, the chips are stored in the Horso without flowing out. The section of the scraped polyethylene pipe is circular and is held by a spiral groove so as not to fall off.
