    摘要: An object of improvement is a threading tool that includes multiple cutting edges 3 -1 to 3 -n (where n is 5 in the drawings) disposed side by side and that performs threading successively using the multiple cutting edges to form a thread. At least one of the cutting edges of the tool except a finishing edge 3 -5 is deviated in an opposite-to-feed-direction direction of the tool (may instead be the feed direction).

    摘要: There is provided a cutting insert for threading work for achieving high shape accuracy of a screw to be processed, as well as low costs. Therefore in the cutting insert for threading work, a plurality of mountain-shaped cutting edges are formed in a cross ridge line portion between a rake face (2) formed on an upper face and flanks formed in a side face as viewed from a side of the rake face (2), wherein the cutting edge comprises at least one finishing cutting edge (6a) for transferring a shape of a screw, and at least one roughing cutting edge (6b)formed in a mountain shape smaller than that of the finishing cutting edge (6a) as viewed from a side of the rake face (2). A flank (4a) of the finishing cutting edge (6a) includes a first flank (5a), and a second flank (5b) having a clearance angle larger than that of the first flank (5a) as viewed in a normal direction of the cutting edge, wherein the finishing cutting edge (6a), the first flank (5a), and the second flank (5b) are sequentially provided in that order.
