Drill Bits

Dock framing calls for holes that ordinary drill bits are not built to make: long bolt holes through wet treated timber, deep bores through pilings, clean pilots for lag screws in dense lumber. A bit that works fine in framing lumber binds and burns in green treated timber.

Dock Builders Supply stocks drill bits specified for this work, including ship auger bits for deep bores, spade bits for fast rough holes, and twist bits for pilots and hardware.

Size your pilots correctly for your lag bolts to get full holding power without splitting the timber. See also driver bits and all tools and equipment. Call us if you need help sizing a bit for a specific fastener.
