Description

1/4″ x 19 BSPF Spiral Flute HSS-Co5 Tap – Goliath
HSS Bright Finish BSPF Spiral Flute Machine Tap.
HSS-Co Spiral Flute Taps.
Spiral Flute taps are designed primarily for machine tapping of blind holes.
They are used to the best advantage in materials that produce long continuous chips.
The right hand spiral forces the swarf out of the hole and prevents the chips from clogging at the bottom of the hole or in the flutes, which could cause tap breakage or spoiled threads.
British Standard Pipe – G Series (BSPF) is a pipe thread which is used mainly for mechanical coupling.
The angle of thread is mainly 55º however for the US method some threads have a 60º angle.
It is specified according to JIS and ISO R228.
Manufactured from HSS-Co5.
