The Bordo 3/4" x 14 BSPT Bottoming HSS Tap is a robust pipe-threading tool from Bordo’s High Speed Steel (HSS) BSPT (British Standard Pipe Taper / RC Series) range, engineered to cut accurate internal tapered threads with full thread depth. Ideal for plumbing, fluid systems and mechanical coupling applications where a strong, sealed connection is essential, this bottoming tap completes threads right to the base of blind holes for maximum engagement.
Manufactured from premium high speed steel, this 3/4" diameter tap features a 14 threads-per-inch (TPI) BSPT thread form based on the Whitworth V-thread profile (55° angle) and a “1 in 16” taper — meaning the diameter increases as the taper lengthens to help form a thread seal when tightened. Bottoming taps have a short lead (two threads) to minimise thread run-out, making this tool the final tap in a multi-step threading sequence after taper and intermediate taps. Designed for hand or general machine use, it performs reliably in medium tensile materials such as brass, aluminium and mild steel.
Bordo quality engineering provides dependable results in pipe threading and mechanical assembly tasks. With Industrial Shed’s fast dispatch and trade support, you’ll have the right threading tool ready when you need it.
