RAILROAD TIE BORE BIT

The Most Widely Used Railroad Bit Design

 
Ideal for drilling railroad cross ties, landscape timbers, marine piles, and thick salt treated posts. The unique point geometry and hollow flute design is self feeding without the aid of a lead screw.  The RAILROAD TIE BORE BIT makes an excellent exit hole while keeping "blowout" to a minimum. The RAILROAD TIE BORE BIT can be provided with various shank configurations, the most common is the 1/2" Round Shank with 0, 1 or 3 flats.  This allows the drill bit to be chucked into a " Jacobs Chuck or larger drill. Made from high quality American tools steel on precision CNC grinders. A "must have" for any job that requires a through hole in a thick timber of spikes or bolts.
  • Designed to Drill Spike Hole in Wood Railroad Cross Ties / Sleeper
  • The open flute design prevents chip packing and reduces wood burning.
  • Single & Double Flute available w/ custom flute length and tip angle. Tip Geometry Designed to be self feeding.
