Bordo – 7/8″ x 9 UNC Bottoming HSS Tap | 3032-7/8B
The Bordo 7/8″ x 9 UNC Bottoming HSS Tap is a precision threading tool engineered to create full-depth internal threads to the Unified National Coarse (UNC) standard. Designed for both hand and general machine use, this bottoming tap ensures reliable, accurate threads — especially in blind hole applications where maximum thread engagement is required.
Manufactured from high speed steel (HSS), this thread-cutting tap features a bottoming flute design with a reduced lead of two threads, providing minimal thread run-out and complete thread formation right to the bottom of blind holes. With a 7/8″ major diameter and 9 threads per inch (TPI), it’s ideal for standard coarse-thread fasteners used across metal fabrication, maintenance, engineering and industrial applications. The robust HSS construction delivers durability and wear resistance for dependable performance in materials such as aluminium, brass, bronze and plastics.
Bordo is recognised across Australia for quality tooling and consistent manufacturing standards. Industrial Shed gives you fast access to these trusted trade-grade threading taps for efficient and accurate workshop and on-site work.
