Engineered for high-productivity blind hole thread production, this collection of Guhring UNF 35-Degree spiral flute gold ring taps delivers superior chip evacuation when tapping high-tensile alloys and hardened steels. Manufactured from premium powder metallurgy high-speed steel (HSSE-PM) and finished with a wear-resistant titanium aluminum nitride (TiAlN) coating, these industrial machine taps are purpose-built to withstand the extreme thermal loads encountered when threading tough materials. For local engineering shops fabricating heavy machinery or structural infrastructure across Australia, these high-performance gold ring taps resolve common mechanical troubleshooting headaches—such as premature cutting edge chipping, bird-nesting swarf jams, and thread stripping—when working with tough structural steels, including Australian AS/NZS 1594 hot-rolled steel and AS/NZS 3678 grade 250 or grade 350 plate.
