The Bordo 1/2" x 14 BSPF Bottoming HSS Tap is a precision threading tool engineered to cut full-depth internal British Standard Pipe Fine (BSPF) threads into blind holes with excellent engagement and minimal run-out. Part of Bordo’s trusted High Speed Steel (HSS) BSPF (G Series) tap range, this bottoming tap is ideal for tradespeople, plumbers and fabricators requiring reliable pipe threads for mechanical couplings, fittings or fluid assemblies. BSPF threads are specified under ISO R228 and widely used in workshop and industrial pipework applications.
Constructed from premium HSS for strength and wear resistance, this bottoming tap features a lead-in of two threads, allowing you to thread right to the bottom of blind holes while maintaining strong thread quality and engagement. The 1/2" diameter and 14 threads per inch (TPI) BSPF thread form deliver dependable performance in medium tensile materials. Bottoming taps are typically used after a taper or intermediate BSPF tap to complete the thread to the full depth required in precision applications.
Bordo is recognised across Australia for supplying dependable industrial cutting tools built to professional standards. Industrial Shed ensures you have fast access to trusted trade-grade taps when you need them on site or in the workshop.
