Disclosed are a drill and an insert for a drill having improved centering capability and cutting performance. A drill of the present invention processes a relief surface in the center of a cutting edge portion into a flat surface and processes a relief surface on the outer circumferential portion which is connected from the center to the outer circumferential surface into a curved surface, thereby enhancing centering capability and minimizing generation of drill vibration and burr. In addition, the drill of the present invention identically processes the tangential angle of a relief surface, which comes into contact with a hole, regardless of the outer diameter size of the drill, thereby achieving uniform performance even if the outer diameter of the drill varies.

Provided is a drill insert including: a chisel for setting a center point of a hole at a cutting object when the hole is machined; a cutting edge for cutting the cutting object during rotation thereof; and multiple web thinning parts having at least two cutting edges disposed opposite to each other with the chisel interposed therebetween to bring the cutting object in point contact with the chisel. Therefore, by providing the multiple web thinning parts, it is possible to reduce the thickness of the chisel, to more readily perform self centering, to reduce propulsion, and to increase cutting efficiency. In addition, since chips generated during the cutting have a shape to be effectively discharged, it is possible to reduce damage due to friction against the chips and to lengthen lifespan.
