ISO Rolling Taps With No Coating

ISO Rolling Taps With No Coating is manufactured by Wilson. Like coated rolling taps, uncoated rolling taps also rely on their own multi edge structure to apply continuous and uniform squeezing force to the metal on the hole wall during the process of screwing into the workpiece. Under this external force, the metal material undergoes plastic flow and redistribution, gradually forming a precise thread shape. The entire processing process does not involve metal cutting, but rather completes the formation of threads through plastic deformation of the metal.

This tap is suitable for materials with good plasticity and low hardness, such as pure aluminum, pure copper, and low carbon steel. When processing such materials, efficient processing can be achieved by utilizing the plastic properties of metals, which has won a good reputation among non-ferrous metal processing enterprises.

Suitable materials for processing

It likes "soft" materials:

This uncoated rolling tap is best suited for materials that are "plastic" (in other words, soft and easily deformed) and "not hard". For example, non-ferrous metals such as pure aluminum and copper, as well as less hard iron materials such as low-carbon steel. When dealing with these materials, the tap can effectively exert its "rolling" ability - just like using a rolling pin to press out the dough, squeezing out the threads quickly and effectively.

Suitable processing scenarios

This type of uncoated tap is generally used in situations where extreme thread accuracy is not required, or in small-scale production. For example:

Make some ordinary parts, the requirements for threads are not so high.

The batch size is not large, just make dozens or hundreds of them, there is no need to use expensive tools.

Or when conducting research and development, or trying out new products. At that time, the quantity was small, and the main consideration was the cost. It was quite suitable to use this uncoated tap to test a sample.

Accuracy and Quality

Although it can also meet international standards (ISO standards), compared to coated ones, it is a bit "unsustainable". Because without that layer of armor, its wear resistance and friction resistance are average. As you use it, the tap itself will also wear out. When the wear is severe, the precision and surface smoothness of the threads it processes will decrease.
