Description:

The Irwin R17A1-12 Auger Bit is built for clean, fast wood boring in heavy-duty applications. With a 1-1/2" diameter and 12" flute length, this bit is ideal for drilling deep holes in framing lumber, utility poles, and other wood materials — even where nails may be present.

Its single cutter and side lip design delivers smooth cutting performance and is capable of cutting through embedded nails without damaging the bit. The full-length heat-treated construction reinforces the bit against bending in high-torque applications and strengthens the twist at critical stress points. A hollow center flute quickly removes chips for faster, more efficient drilling, while wide lands keep the bit tracking straight.

The 7/16" hex shank ensures a secure grip in power drills and impact tools.
