Wilson is JIS Rolling Taps’ Supplier. The products are chipless tapping tools manufactured in accordance with Japanese industrial Standards (JIS). Their core principle is to form threads through extrusion rather than cutting. As no chips are produced, it fundamentally solves the chip removal problem and effectively avoids the risk of tap breakage caused by chip blockage. Therefore, it is highly favored in precision manufacturing fields such as automotive parts and electronic equipment, where the quality and cleanliness of threads are extremely high.
In terms of specifications and precision,JIS Rolling Taps strictly follow the JIS standard series. They can be classified into JIS Rolling Taps With Coating and JIS Rolling Taps With No Coating according to the coating. Moreover, the size and precision requirements of its bottom hole are extremely strict. A dedicated extrusion bottom hole drill bit must be used to ensure that the metal can flow evenly and fully during the extrusion process, thereby forming a perfect thread.
Although JIS Rolling Taps have significant advantages in processing efficiency, thread quality and tool life, their application is also accompanied by a relatively high technical threshold. Therefore, it is more suitable for large-scale, automated and stable production environments, and is an indispensable key cutting tool for high-end manufacturing enterprises that pursue ultimate thread performance and economic benefits.
