The Bordo 1/2" x 20 UNF Taper HSS Tap is a professional threading tool from Bordo’s High Speed Steel range, engineered to cut fine internal UNF (Unified National Fine) threads with precision, durability and reliability. Designed for both hand and general machine use, this taper tap provides smooth thread engagement and dependable performance for workshop and trade applications.
Manufactured from premium High Speed Steel (HSS) and featuring a taper lead (approximately 8 threads to full size), this tap makes starting threads easier — especially in difficult entry surfaces or where alignment is critical. The 1/2" major diameter with 20 threads per inch (TPI) conforms to the UNF standard, offering a fine-pitch thread form that provides greater tensile stress area and better resistance to stripping compared to coarse thread counterparts. Ideal for use in medium tensile materials including aluminium, brass, bronze, plastics and mild steels, this tap is suitable for general-purpose tapping, fabrication, maintenance and repair work in both workshop and on-site settings.
Bordo is a trusted industrial tooling brand in Australia, known for quality manufacturing and dependable cutting tools. Industrial Shed ensures you have fast access to this precision threading solution whenever you need it.
