The Bordo 1/2" x 13 UNC Bottoming HSS Tap is a precision-engineered threading tool designed to produce accurate, full-depth internal threads — especially in blind hole applications where minimal thread run-out is essential. Built for general purpose threading tasks in medium tensile strength materials, this bottoming tap delivers consistent performance for workshop, maintenance and on-site trade use.
Manufactured from high speed steel (HSS), this Bottoming UNC tap features a bottoming lead with just two threads of lead-in, enabling it to cut deep threads right to the bottom of a blind hole with excellent control. The 1/2" diameter with 13 threads per inch (TPI) conforms to the Unified National Coarse (UNC) standard, a widely used thread form in manufacturing and assembly applications. Ideal for threading into aluminium, brass, bronze, plastics and similar materials, this tap is suitable for both hand and general machine tapping operations — making it a dependable choice for tradespeople, fabricators and maintenance professionals.
Bordo has a strong reputation for quality tooling backed by reliable manufacturing standards. Industrial Shed brings you fast access to these trusted trade-grade taps so you’re equipped with the right tool when you need it most.
