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.

Please call 800 435-2965 for current prices.
