Goliath BSW Spiral Point (Gun) HSS-Co5 Bright Tap

  • HSS-Co (Cobalt) Bright Finish BSW 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 Whitworth angle of thread is 55 degrees as opposed to 60 degrees in Metric and Unified threads.
  • This thread form was developed by Sir Joseph Whitworth in 1841.
  • The thread form has rounded roots and crests and is specified in BS84:1956.
  • 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.
