Threading Tangential Chaser

The Threading Tangential Chaser is used in pipe, bolt, rod, bar and steel pipe threading machines. This is manufactured from imported high-speed steel, which must pass exacting metallurgical standard. NCT chaser is designed as per International threading standard, provides line contact with the work to provide natural clearance comparable to that of a lathe tool. Friction at the cutting edge, thread distortion and chaser wear are minimised the tangential location of the chaser, in respect to the work places in a direct line with the cutting action exerted in forming the thread. Depending upon the size of the die head in which they are used, this varies in length from 1" to 8". During the re-sharpening process it is unnecessary to remove the same amount of metal from each chaser in the set. Stock inventories are reduced as the same set of NCT tangential chasers can be used to produce all diameters within the range of the die head requiring the same pitch.
