Engineered specifically for high-efficiency through hole thread production in ductile materials, this collection of Guhring UNF spiral point gun taps with a distinct yellow ring identifier features a premium uncoated bright finish. This polished bright finish reduces friction and prevents cold welding or built-up edge (BUE) when machining low-to-medium tensile steels. The specialized geometric design features a spiral point that drives chips forward out of the pre-drilled hole, completely mitigating the risk of swarf re-cutting. Manufactured from heavy-duty high-speed cobalt steel (HSSE), these machine production taps are optimized for reliable performance in general engineering applications.
