The Bordo 6G x 40 UNF Bottoming HSS Tap is a precision threading tool from Bordo’s High Speed Steel range, engineered to produce fine Unified National Fine (UNF) threads right to the bottom of blind holes. Ideal for workshop, fabrication and trade environments, this bottoming tap delivers excellent thread quality and accuracy for internal thread cutting applications.
Manufactured from premium High Speed Steel (HSS), this tap features a bottoming lead with only two threads, ensuring minimal thread run-out and maximum thread engagement in blind hole applications. The 6G major diameter and 40 threads per inch (TPI) conform to the UNF (Unified National Fine) thread standard — a fine-pitch form that offers superior tensile stress area and better resistance to thread stripping compared to coarser thread forms. Designed for hand or general machine use, this tap is suitable for a wide range of medium tensile materials including aluminium, brass, bronze, plastics and mild steels.
Bordo is a trusted industrial tooling brand in Australia known for producing reliable and high-quality taps and threading tools, and Industrial Shed ensures fast access to this essential UNF bottoming tap when you need it on site or in the workshop.
