The Bordo 7/8" x 9 BSW HSS Tap Set is a comprehensive British Standard Whitworth (BSW) hand and machine tap set engineered for complete internal thread cutting performance in medium tensile materials. This full set contains the progressive sequence of BSW taps — taper, intermediate and bottoming — to take you from the initial thread start right through to full-depth threads with minimal run-out, making it perfect for fabrication, maintenance, engineering and industrial applications that require traditional Whitworth thread forms.
Manufactured from premium High Speed Steel (HSS), this tap set features the classic BSW thread form with a **55° thread angle and rounded roots and crests**, originally developed by Sir Joseph Whitworth and specified under British Standard **BS84:1956**. The taper tap guides the thread start with ease, the intermediate tap cuts threads true to the pilot hole, and the bottoming tap finishes full-depth threading — all suitable for both hand tapping and general machine use.
Bordo is recognised for precision engineered threading tools built to trade and industrial standards. Industrial Shed ensures fast access to this trusted BSW tap set when consistent, professional threading results are needed on site or in the workshop.
