    摘要： A cutting tool for boring including a cutting insert fixed at a front end of a bar-shaped holder. The holder includes a cutting surface-sided chip pocket that is concave with respect to the outer circumferential surface of the holder, the cutting edge end of the cutting insert protruding from the outer circumferential surface of the holder, and the cutting surface-sided chip pocket having a bottom surface facing the portion of outer circumferential surface where the cutting edge overhangs. Further, an cutting edge-sided chip pocket is formed at the portion of outer circumferential surface where the cutting edge overhangs such that the edge of the portion of outer circumferential surface where the cutting edge overhangs is concave with respect to the outer circumferential surface of the holder, on the bottom of the cutting surface-sided chip pocket when viewed from the cutting surface.
