The Bordo 1-1/4″ x 12 UNF Bottoming HSS Tap is a professional-grade fine thread cutting tool from Bordo’s High Speed Steel range, engineered to produce Unified National Fine (UNF) threads right to the bottom of blind holes with minimal thread run-out. Built for workshop and trade environments, this bottoming tap delivers precise internal threads and dependable performance for both hand and general machine applications.
Manufactured from premium High Speed Steel (HSS), this bottoming tap features a bottoming lead (two threads) to achieve full thread depth in blind hole applications. The 1-1/4″ major diameter with 12 threads per inch (TPI) conforms to the UNF standard, providing a fine-pitch thread form that offers increased tensile stress area and improved resistance to thread stripping compared to coarse thread forms — ideal for medium tensile materials such as aluminium, brass, bronze, plastics and mild steels.
Bordo is a trusted industrial tooling name in Australia, known for high-quality taps and dies designed for reliable performance on site and in the workshop. Industrial Shed ensures fast access to this essential bottoming tap whenever you need it.
