About this item:
- 3/8" x 19 BSPF Spiral Point (GUN) HSS-Co5 Tap - Goliath
- HSS Bright Finish BSPF Spiral Point Machine Tap.
- HSS-Co Spiral Point (Gun Nose) Taps.
- Spiral point taps, also known as 'Gun nose taps', have straight flutes supplemented by angular cutting faces at the lead.
- The design of the cutting portion propels the swarf ahead of the tap leaving the flutes clear for the flow of coolant to the cutting teeth.
- Primarily designed for use in through holes, these taps can be used in blind holes provided that there is ample clearance beyond the threaded section to accommodate the swarf.
- The advantages of a gun nose tap are the shearing action of the angular cutting faces, which produces a fine finish on the threads and shallower flutes.
- This allows a stronger cross section throughout the tap.
- 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.
- Manufactured from HSS-Co5, this modern design tap uses straight flutes supplemented by angular cutting faces at the point to produce a fine finish on the threads.
- Shallower flutes achieve a stronger cross section allowing the tap to withstand greater cutting forces.
