The Bordo 1/4" x 19 BSPF Bottoming HSS Tap is a specialised threading tool from Bordo’s High Speed Steel (HSS) pipe thread tap range, engineered to cut precise British Standard Pipe Parallel Fine (BSPF / G-Series) internal threads to full depth. With a bottoming lead designed for minimal thread run-out, this tap is ideal for completing pipe threads at the base of blind holes in workshop, plumbing, fabrication and trade applications.
Manufactured from robust high speed steel, this 1/4" BSPF bottoming tap features a 19 threads-per-inch (TPI) fine pipe thread profile — conforming to the BSPF (parallel) standard commonly used for mechanical pipe couplings and fittings where strong, accurate thread engagement is essential. The bottoming lead (two threaded lead) ensures you achieve maximum usable thread depth when following up a taper or intermediate tap. Designed for hand or general machine use in medium tensile materials, this tap delivers clean, accurate threads time after time.
Bordo is a trusted name in precision cutting and threading tools, and this BSPF bottoming tap brings reliable performance to your tooling kit. With Industrial Shed’s fast dispatch and trade support, you’ll have the right tool ready when you need it.
