Goliath BSPF Bottoming HSS Bright Pipe Tap

HSS Bright Finish BSPF Hand and Machine Bottoming Tap.
Pipe taps 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.
British Standard Pipe - G Series (BSPF) is a pipe thread which is used mainly for mechanical coupling.
The angle of thread is mainly 55° however for the US method some threads have a 60° angle.
It is specified according to JIS and ISO R228.
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.
Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
