Bordo 1/2″ x 26 Brass Intermediate HSS Tap

Description

1/2″ x 26 Brass Intermediate HSS Tap
HSS BSB Intermediate Hand and Machine Tap.
British Standard Brass (BSB or simply “Brass”).
Brass tubing has a uniform wall thickness, irrespective of the tube diameter, therefore any thread cut on, or in, it needs to have the same depth, so 26 TPI is standard on all BSB diameters. BSB is often confused with BS Cycle thread, the difference being that brass thread has an angle of 55º whereas Cycle is 60º.
Intermediate Taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
