1-1/8" X 7.5" Wedltec Ship Auger Bit 1779347-SBD

Irwin's 7.5" WeldTec Ship Auger Bit is engineered for superior durability and performance, particularly when boring holes in wood where nails may be encountered. Its key advantage is the Patent Pending Welded Cutting Edge, which is made of a harder material welded to the base, resulting in 2X Nail Cutting Life compared to standard IRWIN ship augers and allowing it to cut through nails without damage. The bit features a High-Speed Steel construction and a Fully Forged Body (for diameters 3/4" and larger), providing a full-length heat-treated body that guards against bending in heavy-duty applications. Chip clearing is efficient due to the Wide Flutes and hollow center, making it ideal for tough materials like green wood and creosoted poles. It has a 7/16" Quick Change Impact Shank with a diameter of 0.437 inches and a total drilling depth/length of 7.5 inches. The bit is backed by a Lifetime Warranty against Manufacturer's Defects.
