    摘要： It is an object of the invention to provide a thread-forming tap to which a chamfer can easily be mounted, and a general threading method. The thread forming tap of the invention has a threaded portion comprising a tapered chamfer and a parallel threaded portion which is formed continuously with the chamfer. A depth of root of the chamfer is set equal to that of a root of the parallel threaded portion constantly.

    摘要： A tap having a reamer edge which is provided at a chamfer part, so that when the thread forming tap is pulled out after the internal thread is formed, a seam portion present at the crest of the internal thread is cut off, whereby even in a blind hole, formation of internal thread and cutting of the seam portion are performed in a single process, and formation of an internal thread and processing of an inside diameter portion are achieved in a single process to obtain concentricity in line with each other. Further, even if there is a deviation in diameter of the hole before threading, the inside of the internal thread is processed to a constant value.

    摘要： A thread tapping cutting tool includes a working part with a chamfer portion, control portion, and at least two thread cutting wings (separated by flutes) formed therein. The chamfer portion is at least one half of the length of the working part. Each of the two or more thread cutting wings has a width of not more than 0.2 times a tap drill outer diameter of the working part, and not less than 0.02 times the tap drill outer diameter. The chamfer portion has plane surface lands on the cutting wings at the outer edge, and a relief angle of the plane surface lands is greater than 5 degrees. The core diameter of the cutting wings is defined by the depth of the flutes, and is not more than 0.35 times the tap drill outer diameter.

    摘要： A set of multitooth thread chasers with their teeth shaped and arranged to perform a succession of central roughing cuts of approximately trapezoidal cross section, respectively, and of successively decrescent areas. The chasers are free from any portions which can cause flanking cuts which result in lateral flanges on the resultant chips. The cut produced by each tooth extends close to, but terminates a few thousandths of an inch short of, the flanks of two adjacent threads so that, in the final rough-cut thread, a very thin layer of metal remains between the rough-cut thread surface and the thread finish lines, and this layer is continuous and uninterrupted along the entire final rough-cut thread surface. This layer is removed by a single finishing tooth which makes a single finish cut concurrently cutting a portion of one crest, along the thread trough and flanks and a portion of the adjacent crest, thus cutting over a length of thread cross section equivalent to one complete thread.
