Bordo – 1-1/8" x 7 BSW Taper HSS Tap | 3028-1.1/8T

The Bordo 1-1/8" x 7 BSW Taper HSS Tap is a professional-grade British Standard Whitworth (BSW) thread cutting tool engineered for precision internal thread starts in medium tensile materials. Designed for workshop, fabrication and general industry use, this taper tap provides controlled thread engagement and reliable performance when initiating BSW threads in both blind and through holes. ([bordo.com.au](https://www.bordo.com.au/products/bordo/taps-dies/hss-hand-and-br-machine-taps/hss-tap-br-bsw), )

Manufactured from high-speed steel (HSS) with the classic BSW thread form, this tap features a 55° thread angle with rounded roots and crests — the traditional Whitworth standard originally developed in 1841 and specified under BS84:1956. The taper lead (eight threads of gradual engagement) allows easier entry into the pre-drilled hole, reducing risk of breakage and improving cutting control. The 1-1/8" diameter with 7 threads per inch (TPI) makes it suitable for internal thread cutting in a variety of machinable materials, and ideal for both hand and general machine tapping operations.
