1/2 Inch Dual Purpose Boring Bar Assembly



  • ½ inch Boring Bar
  • Set Screws
  • Allen Key
  • ½ to ¾ inch bushing
  • 3/16 inch HSS cutter




This boring bar was designed the same as the ¾ inch boring bar, which has a dual purpose.  On one end the 3/16 inch cutter is straight out the end.  The cutter is held with a set screw dedicated straight out.  On the other end of the boring bar the cutter is on a 45 degree angle and secured with a set screw.  This versatility allows reach into any shape vessel.  Two bars for the price of one, also compatible with the Hunter-Jamieson nanograin carbide cutter.

This allows the entry into very small mouth openings.  An example would be to reach and hollow Christmas ornaments and small lidded boxes.  It is ideal for any small vessel hollowing up to 6 inches tall.
