Spiral screw in tapping, to increase its rotation of the spiral groove, can easily cut iron from the hole, so as to avoid iron residue or blockage in the trench, caused by tapping broken edge crack, so it can increase the life of wire tapping and cutting out the thread of the highest precision. Spiral wire tapping is suitable for cutting high toughness materials, but not suitable for fine chips such as cast iron.
