Irwin R17A1-516 1-5/16" Auger Bit – 7/16" Hex Shank
Description:
The Irwin R17A1-516 Auger Bit is engineered for clean, efficient wood boring in demanding jobsite conditions. With a 1-5/16" diameter and 12" flute length, this bit is ideal for drilling deep holes in framing lumber, construction timbers, and other wood materials — including nail-embedded wood.
The single cutter and side lip design provides smooth cutting performance and allows the bit to cut through embedded nails without damaging the cutting edge. Full-length heat treatment strengthens the bit and reduces bending in heavy-duty applications. A hollow center flute clears chips quickly to improve drilling speed, while wide lands help guide the bit for straighter, more accurate holes.
The 7/16" hex shank ensures a secure, slip-resistant fit in standard power drills and impact tools.
