The Bordo 1-1/8" x 7 UNC Bottoming HSS Tap is a premium threading tool from Bordo’s High Speed Steel (HSS) hand and machine tap range, engineered to cut robust Unified National Coarse (UNC) internal threads. Featuring a bottoming lead, this tap is ideal for producing full-depth threads at the base of blind holes — making it a trusted choice for professional trades, fabrication work and workshop threading tasks.
Manufactured from durable high speed steel, the 1-1/8" tap delivers a 7 threads-per-inch UNC profile with a bottoming lead designed to minimise thread run-out, ensuring maximum usable thread depth when finishing blind holes. The UNC thread form is widely used in industrial, mechanical and fastening applications, particularly in lower tensile strength materials such as bronze, brass, aluminium and plastics. This bottoming tap performs reliably when used after a taper or intermediate tap, and is suitable for both hand and general machine tapping applications.
Bordo’s quality engineering and trusted manufacturing standards ensure dependable performance on every threading job. With Industrial Shed’s fast dispatch and trade support, you’ll have the right threading tools ready when you need them most.
