What is a tap and die?

Tap and matrix are tools used for cutting threads on empty material and in holes to customize screws and screws. Kits and Earth usually consist of corresponding taps and die in all common screw sizes, along with keys that help the user hold and turn the tap and die. Click is a metal rod resembling a drill that has a cutting edge machined into a rod to create female threads below the surface. And die is a round piece of metal with opening in the center; The sides of the opening are machined by cutting playing for creating male threads on an empty screw or rod. Depending on the type of set, the fibers may be cut to metals, plastics and wood. When the hard materials are tapped, the hole is drilled slightly smaller than the tap diameter. Click is placed in the holding key supplied with the set and the tip is re -placed hole. For larger holes, or when a particularly hard material is tapped, the smaller ones are sometimes used for the initial holeUtky. Subsequent taps using gradually use wider kick diameters

In order to create male threads on the rod or empty screw, the ground threads corresponding to the tap are used and placed in the holding key designed for the matrix. The rod or empty screw is inserted into the matrix and the matrix turns until the required number of threads is cut into the outer part of the rod or screw. The dependent piece is now ready to screw into the threaded hole made by a cock.

For commercial and industrial use, the kits and death are used with electric tools and operate in the same way as hand -operated sets. The taps are inserted into a drilling press or power drill and dies are inserted into a lathe or similar tool for fond of a rod or screw. For volumetric work in factories, complex multiple taps and death and specialized machines are often used.

Clicking on the machinery is sometimes used to help the operator in hand on his hand straight holes to the surface. When working with metal, an oil -based grease is usually used on the tap and death. This generally helps reduce friction and stress on the instrument.
