Tools & Gear Taps & Dies HSS Hand and Machine Taps

Pipe Taps Pipe Taps are supplied with PARALLEL threads or TAPER threads. They are much shorter than a similar size of regular hand tap - but the design features are the same. Goliath HSS taps provide a high hardness to toughness ratio - compressive and tensile strength - good abrasion resistance and resistance to micro-chipping - ensuring a long tool life. Parallel Pipe Taps are used for parallel threading by hand or machine. NPS (PARALLEL)NATIONAL PIPE STRAIGHT - Made to American Standards) Used for free-fitting mechanical joints where thread sealing is not required. BOTTOMING TAPS have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole. Manufactured from HSS this parallel pipe tap is used for parallel threading in medium tensile materials and is for hand or general machine use.
