Irwin 11/16 In. I-100 Auger
The I-100 auger bits feature a solid center design which provides extra rigidity while boring. The wide lands keep the bit straight as it bores through the hole.
Single-spur cutting edge scribes the circumference of the hole for a smoother finish
Coarse screw point provides fast boring in hard and soft woods
All bits have a 4-1/2 In. twist length and a 7-1/2 In. overall length
Full-length heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs
