Abstract
A drill bit includes a tool body having a main body in the form of a cylinder. A chip removing structure is provided on the main body. The tool body has a distal end provided with a clamping slot and a cutter inlaid in the clamping slot. The cutter has at least two blade portions arranged circumferentially on the distal end of the tool body and extending radially relative to the tool body. Each of the blade portions has a front side along the drill bit's rotating direction and a back side against the rotating direction. The clamping slot covers the back side of one blade portion by an area larger than that used to cover the front side of the same blade portion.
