The Bordo ⅝″ x 14 BSPF Bottoming HSS Tap is a professional threading tool designed to produce full-depth internal pipe threads to the British Standard Pipe Parallel (BSPF) specification. This bottoming tap is engineered for use in hand and general machine tapping, delivering complete thread engagement in blind hole applications where maximum thread depth and minimal run-out are critical.
Manufactured from durable High Speed Steel (HSS), this BSPF bottoming tap features a 14 threads per inch (TPI) pitch and a ⅝″ major diameter, conforming to BSPF (G Series) standards commonly used in mechanical and fluid system couplings. The bottoming flute design has a reduced two-thread lead, enabling the tap to cut threads all the way to the bottom of the hole after initial threading with a taper or intermediate tap. Its robust HSS build makes it suitable for a variety of medium tensile materials including steel, aluminium, brass and workshop plastics.
Bordo threading tools are recognised across Australia for their industrial reliability and quality manufacture. Industrial Shed makes these trusted trade-grade BSPF taps readily available so you can tackle precision pipe threading jobs with confidence.
