Groove shape and long row major:

The lower part of the screw tap, spiral groove to tapping blind holes, cutting no residue, easy to eat into the bottom, has good machinability. For a continuous coiled material, the inner wall of the blind hole, with uranium to cutting holes in cutting;

Tip tap, From the front, the cutting edge inclination slot discharge, no cutting congestion, flexural strength, sharp cutting performance loss. Application of continuous coiled material, through hole and inner wall with uranium to high-speed cutting groove hole, machining in cutting;

Extrusion screw tap The use of plastic machining principle of internal thread, without cutting discharge, internal thread accuracy is very stable, the flexural strength loss. In the application of good extension materials, and through hole and blind hole;

Straight fluted tap Straight groove, edge strength, cutting cone length, easy grinding easily applicable in processing materials with high hardness, easy to cause the cutting tool wear materials, powder materials, tapping short holes, blind hole depth.
