The Bordo 1-3/4" x 5 BSW HSS Tap Set is a premium British Standard Whitworth (BSW) hand and machine tap set engineered for complete thread cutting performance in medium tensile materials. Designed for workshop, fabrication and industrial applications requiring traditional Whitworth threading, this comprehensive set includes the full sequence of taper, intermediate and bottoming taps to take you from initial thread start to full-depth thread engagement with minimal run-out.
Manufactured from premium High Speed Steel (HSS), this tap set uses the classic BSW thread form with a **55° thread angle and rounded roots and crests**, developed by Sir Joseph Whitworth and specified under BS84:1956. The set includes a taper tap to ease entry, an intermediate tap for sizing true to the pilot hole, and a bottoming tap to finish threads to full depth — suitable for both hand tapping and general machine use.
Bordo is a trusted name in precision engineered tooling built to industrial standards. Industrial Shed ensures you have fast access to this dependable BSW HSS tap set when you need reliable threading performance on site or in the workshop.
