Title: drilling tool
Inventor: SIN KWANG JIN
IPC: E21B10/627
Filed: 2015-05-07
Abstract: The present invention relates to a drilling blade used if deeply drilling into the ground in a prescribed shape. A machined surface is formed on a prescribed portion of a metal body detachably mounted on the drilling blade. A mounting groove of a prescribed depth is formed on the machined surface. A cemented carbide tip of a cylindrical body is forcibly pressed in the mounting groove by a pressing means such as a press or the like to employ the cemented carbide tip by a forcible pressing method instead of welding to facilitate manufacture and work. Since the cemented carbide tip is not pressed to an appropriate depth by airtightness when mounting, the shape of the mounting groove is machined to allow a middle portion of a bottom surface of the mounting groove to be inwardly inclined to apply a pressure in the mounting groove produced when pressing in a vacuum pressure while mounted to sturdily mount the cemented carbide tip of the cylindrical body. An exposed front end of the cemented carbide tip is machined to be curved. The cemented carbide tip is mounted to expose only the machined curved portion on the machined surface of a drilling tool to eliminate a large load on a main body of the cemented carbide tip and minimize damage to the cemented carbide tip if drilling into the ground by rotation.
