Ship Auger Bits

Ship auger bits are the tool for boring all the way through a piling or a stack of heavy timbers in one pass. The screw point pulls the bit through, the deep single flute clears chips out of a long bore instead of packing them, and the result is a clean straight hole that your bolt actually slides through.

Dock Builders Supply stocks ship augers in a range of diameters and lengths sized to dock framing bolts and piling dimensions.

Match the bit diameter to your hex bolt or carriage bolt size. For shorter, rougher holes, see spade bits. Browse all drill bits and tools and equipment, or call us for help sizing.
