Besly Standard X-Press Taps

Besly X-Press Taps cold form threads in ductile materials such as brass, copper, aluminum and leaded steels. Since X-Press taps have no cutting edges, thread size can be maintained closely. Unusually smooth threads can be formed the full depth of the hole. Size from #8 machine screw and larger have two lubrication grooves to carry lubricant to the forming threads. These grooves help prevent seizing or galling in stringy materials, and provide better performance in deep or cored holes.
