The Bordo 7/8" x 9 BSW Intermediate HSS Tap is a professional-grade British Standard Whitworth (BSW) thread cutting tool engineered for accurate internal thread cutting in medium tensile materials. Ideal for workshop, fabrication and general industrial applications, this intermediate tap produces strong and true internal BSW threads from pre-drilled pilot holes with dependable performance.
Manufactured from high-speed steel (HSS) with the traditional BSW thread form — featuring a 55° thread angle and rounded roots and crests developed by Sir Joseph Whitworth — this tap is designed to handle general purpose threading tasks with smooth engagement and reliable results. Intermediate taps have a four-thread lead, enabling them to cut accurate and well-formed threads in metals and other machinable materials. With a 7/8" diameter and 9 threads per inch (TPI), the 3028-7/8I is suitable for both hand and general machine use.
Bordo is recognised across Australia for producing high-quality industrial tooling backed by robust manufacturing standards. Industrial Shed ensures you have fast access to trusted trade-grade threading tools when you need them on site or in the workshop.
