The Bordo 1-1/8″ x 12 UNF Intermediate HSS Tap is a professional-grade internal threading tool from Bordo’s High Speed Steel range, engineered to produce accurate and durable fine-pitch UNF (Unified National Fine) threads in both hand and general machine applications. Designed for workshop, fabrication and trade environments, this intermediate tap delivers consistent performance for general-purpose threading tasks.
Manufactured from premium High Speed Steel (HSS) with an intermediate lead (four threads), this tap cuts true to the pre-drilled pilot hole while providing excellent thread finish. The 1-1/8″ major diameter with 12 threads per inch (TPI) conforms to the UNF standard, offering a finer pitch that increases tensile stress area and improves resistance to thread stripping compared to coarse-pitch threads. Ideal for use in medium tensile materials such as aluminium, brass, bronze, plastics and mild steels, this tap is suitable for trusted performance in both workshop and on-site applications.
Bordo is a trusted industrial tooling brand in Australia, known for high-quality taps and dies. Industrial Shed ensures you have fast access to this dependable threading tool when you need it on site or in the workshop.
