Bore clean, fast holes through framing lumber with this Irwin WeldTec ship auger bit. A harder cutting edge is welded to the base material, giving about twice the nail-cutting life of a standard Irwin ship auger, so the bit keeps cutting when it runs into embedded nails or other foreign material in remodel and reclaimed framing. The screw tip pulls the bit through the work for fast, clean boring.

• Welded WeldTec cutting edge - about 2x the nail-cutting life of a standard Irwin ship auger
• Cuts through nails and other foreign material in framing
• Screw tip pulls the bit through for fast, clean holes
• Single twist flute, wide for fast chip removal
• Full-length heat treatment
• 1" cutting diameter
• 17" overall length with 12" flute
• 7/16" quick-change hex impact shank

Tip: Ship augers are built for boring through studs and joists to run wire or pipe - on deep holes, back the bit out periodically to clear chips and keep the flute from packing.
