ISO Rolling Taps for Chip-Free Thread Forming

Wilson’s quality ISO Rolling Taps is a type of tap that forms threads on its own after the metal material "flows" through extrusion. Because the entire process contains almost no iron filings, it is also called chipless tapping. This type of tap is highly suitable for processing metals that are relatively "soft" and prone to deformation, such as aluminum alloys, copper alloys and low-carbon steels. The processed thread surface is particularly smooth, with higher strength and less prone to loosening. Therefore, it is very popular in industries with high requirements for thread quality, such as automobiles, aircraft, and mobile phones.

ISO Rolling Taps is usually made of high-speed steel or carbide. Some are also coated, which is known as ISO Rolling Taps With Coating. This makes the taps more wear-resistant and has a longer service life. When using this type of tap, the size of the bottom hole is particularly crucial. It is usually smaller than the nominal diameter of the thread, and the bottom hole must be drilled perfectly round and accurately; otherwise, it is easy to damage the thread or break the tap in the hole.

Although the rolling tap has a fast processing speed, good thread quality and long service life, it has relatively high requirements for machine tools and operation. Once an error occurs during the processing, it is difficult to remedy. Therefore, it is more suitable for large-scale and high-demand production environments. Overall, it is like a "precision cold forging master" in thread processing, using extrusion to transform ordinary holes into solid and high-quality threads.
