Features: BSPF (G SERIES) - British Standard Pipe BSPF (G Series); This series 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. ; Specifications:Diameter1-1/4"Pitch11 tpiLeadingBottomingOverall Length119 mmTapping Drill39.5 mm
