1/2-in Woodboring Auger Drill Bit

  • Solid center design provides extra rigidity while driving
  • Wide lands keep the bit straight as it bores through the hole
  • Flutes are ground behind the lands to funnel chips to the inside of the bit and away from the outside diameter, producing a faster, cleaner cut
  • Single-spur cutting edge scribes the circumference of the hole for a smoother finish
  • Coarse screw point provides fast drilling in hard and soft woods
  • Full-length heat-treated bit guards against bending in heavy-duty applications, and strengthens the twist where the greatest strain occurs
