    摘要： The present invention provides a hole drilling process and a drilling tool. The hole drilling process is for drilling a hole on a supported tube sheet (45) by using a first drilling tool (63a) that can drill a hole with a diameter smaller than that of a mounting hole (60) that is to become a target hole, and a second drilling tool (63b) that can drill a hole with a diameter equal to the diameter of the target hole, the process including: a temporary hole drilling step in which a temporary hole (60A) with a predetermined depth set beforehand is drilled by moving the first drilling tool (63a) to a drilled position set beforehand; a hole measuring step in which a distance (S) between an existing mounting hole (60) and the temporary hole (60A); a drilled position correcting step in which the drilled position is corrected based upon the distance (S) between the mounting hole (60) and the temporary hole (60A); and a target hole drilling step in which the target hole is drilled by moving the second drilling tool (63b) to the corrected drilled position.

    摘要： It is an object to provide a CBN cutting tool using cBN-based sintered bodies which shows high resistance to chipping even when a hard ferric workpiece which is difficult to cut is cut at a high feed rate for high-speed, high-efficiency machining, and which can provide a machined surface that shows superior surface roughness, and improved fatigue life and sealability.
    A cBN-based sintered body of a cutting tip has an arcuate nose 5, a rake face 6, flanks 7 and a negative land 9. One of the cutting edges 10 defined between the negative land 9 and the flanks 7 that serves as an end cutting edge forms an inclination angle β' of not less than 20 degrees and not more than 35 degrees with respect to the rake face. Further, the cutting edges 10 are positioned such that they are the lowest at the apex P of the arcuate nose and gradually rise from the apex P toward two points Q1 and Q2, respectively.
