| <P>PROBLEM TO BE SOLVED: To provide a rock bit capable of reducing a surface pressure from a pit wall and suppressing the occurrence of vibrations. <P>SOLUTION: According to a first embodiment, the rock bit includes a bit body having a journal, a cone capable of rotating relative to the bit body, a bearing between the cone and the journal, and a seal disposed between the cone and the journal to seal up the bearing; the cone has a gauge surface which comes into contact with the sidewall of a pit; and the gauge surface is covered with a diamond composite material, which is preferably spread widely and smoothly over the gauge surface. In a second embodiment, the bit body is provided with a ring bit disposed on its outer periphery. The cone of the tri-cone bit does not have a gauge chip nor a surface chip contacting the sidewall of the pit, but has only a cemented carbide chip contacting the bottom of the pit. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To provide a reamer of a ground drill capable of controlling the increase of pull-in resistance of the reamer to a buried pipe in the case of pulling-in and efficiently carrying out pull-in work of the buried pipe without lowering flexibility and rotation characteristics. SOLUTION: The reamer of the ground drill includes an approximately conical reamer body 8 shortening a diameter toward to a pull-in side and a rod connecting section 24 provided to the end section of a narrow diameter of the reamer body 8 and connected to a rod 3. The reamer body 8 is connected to the buried pipe 1 through a connecting structural body 7 placed to the opposite side to the rod connecting section 24. The connecting structural body 7 has a swivel joint 34 allowing the rotation of the reamer body 8 to the buried pipe 1, and the relevant part of the swivel joint 34 is mostly stored in the reamer body 8.

| PROBLEM TO BE SOLVED: To obtain a tool for drilling for receiving and fixing extremely easily and simply a center drill. SOLUTION: A tool 1 for drilling is formed of two parts consisting of a front drill main body 2 and a back clamping end part 6 to easily fitting and removing a center drill 12. As the center drill 12 is provided with projected parts 14 and 14' in the radial direction on its end part, it can be inserted into the tool 1 for drilling on the clamping side. | ||||||
