摘要： PROBLEM TO BE SOLVED: To provide a small diameter drill which is for use in machining a small-diameter deep hole, and contributes to improvement in hole locational accuracy while preventing degradation of surface roughness on an inner wall surface of the machined hole due to degradation of chip disposal performance.
SOLUTION: According to the small diameter drill (1) for use in machining a printed wiring board, the thickness of a web (10) of a blade portion in the range from the tip of the blade portion (2) to a terminal (4a) of a chip discharging groove, is set to an almost predetermined thickness ranging from 32 to 54% of the diameter (D) of a cutting edge. Further, with respect to a blade cross section, provided that two straight lines in parallel with each other, each connecting between a front side edge (4d) and a rear side edge (4c) in a rotating direction (N) of a concave wall surface (4b) constituting the cutting chip discharging groove (4), are horizontally placed, a diameter (A) of a maximally inscribed circle in the concave wall surfaces (4b) is set to a dimension ranging from 30 to 65% of an interval (B) between the two straight lines.
