Drilling machines with a shaft attached to the cylinder to rapidly rotate the cylinder by transmitting the rotation from the impeller, a drill screwed into the center of the inner surface of the cylinder, and the tip of the drill protruding slightly beyond the front end of the cylinder are already commonly used. The drilling machine used is supported horizontally, and when drilling into a vertical wall, water is constantly poured to provide lubrication and cooling to the hole being drilled. Then the water will flow directly down. Conventionally, methods such as injecting water through a hole in the center of the rotating shaft have been used, but the equipment is expensive and heavy, making it inconvenient to operate. This book was devised in consideration of these facts, and by injecting water into the cylinder from the rear end surface of the cylinder, a large amount of water is guided to the cutting edge, easily and effectively achieving the purpose of cooling and lubrication, and also The purpose of this device is to be able to manufacture it at a low cost, to be lightweight, and to be easy to use by adding it as is to a device of the present invention. At the same time, a short tube 6 having the same diameter as the core portion is attached to the core portion, and the mouth edge 7 of the short tube is bent inward.
It is characterized in that protrusions 8 are obliquely provided on the inner circumferential surface of the □ cylinder so as to cover the upper portions of the respective water passage holes 5 of the cylinder.

The material is inserted into the planting hole and rotated to make the hole (Figure 7). At this time, the hose B is brought close to the mouth hole on the outer end surface of the short tube 6 and water is injected into the tube, but since the mouth edge 7 of the short tube is bent inward, the injected water does not flow out. There is no. Since the short cylinder is rapidly rotating, the injected water is collected around the cylinder by centrifugal force, and is pushed into the water passage hole 5 by the rotating protrusion 8 and enters the cylinder 1 through the hole. It flows along its inner circumferential surface and is poured onto the cutting edge.

耐久力を与える効果が大きい。This invention has a very simple mechanism, is manufactured at low cost, is lightweight, and is not only easy to use, but also has a large lubrication and cooling effect because a large amount of water is poured onto the cutting edge, preventing wear of the blade and making it durable. It has a great empowering effect.

Claims

[Claims]

A diamond blade 2 is attached to the periphery of the tip of the perforated cylinder 1, a shaft 8 for transmitting rotation from the prime mover is attached to the rear end, and a drill 4 is screwed into the center of the inner surface so that the tip protrudes slightly from the front and back of the cylinder. In this cylindrical drilling machine, a water hole 5 is bored near the periphery of the rear end of the cylinder 1, and a short cylinder 6 having the same diameter as the core is attached to the ventral surface. A structure characterized in that the mouth edge 7 of the cylinder is bent inward, and a projecting piece 8 is provided obliquely to the inner peripheral surface of the core so as to cover the upper part of the water passage hole 5 of the cylinder.
