W. L. Brubaker 1/2-20 NF Taper Hand Tap 4 Flute Made in USA.  Initially, 5 available at $5 each.  Increasing discounts will be applied for 2 or more.  

Listed as used, but they are basically new-old stock manufactured "who knows when", but they look great.  

About 3 3/8" long.  The taper is quite gradual with these, about 15 to 18 threads, so starting the thread cutting should be unusually easy.  Please examine the photos closely.

All are in excellent condition, bright and shiny.  All appear to have never been used.  None show any scratches or chips.  None show any damage to any of the cutting teeth.  Bright and shiny, however, there are a few spots of a wee touch of surface corrosion on some shafts due to age.  See the photos.  All 4 sides are shown.  The taps were rotated by 90 degrees for each photo.

They will be oiled and wrapped in wax paper prior to final packaging and shipping.  Shipped via USPS Ground Advantage.

Thanks for looking.
