The Diablo DAG3080 13/16 Inch x 17-1/2 Inch Auger Bit is a long-format wood-boring bit made for fast, clean hole drilling in framing lumber, general wood stock, plywood, and wood with embedded nails. This is an auger bit designed for drilling clean, deep holes in wood and nail-embedded wood. Model number DAG3080. If you need to run pipe, wire, bolts, or anchors through studs, joists, blocking, or built-up wood members, this is the kind of bit that earns its keep.

What separates this bit from a basic wood-boring bit is the cutting geometry. Diablo uses a two-step cutting action to help the bit enter cleanly and keep the hole more controlled as it advances. On the job, that means less wandering at the start and a cleaner finished hole, especially when you're boring through framing members where a sloppy entry can throw off placement.

The Dura-Tip and dual cutting edge design are there for the real-world stuff, not showroom wood. Remodelers, framers, electricians, and plumbers all run into hidden fasteners sooner or later. This bit is built specifically for nail-embedded wood applications, so you are not babying it every time you hit old material. That makes it a practical choice for repair work, additions, and rough-in work where the lumber is not always pristine.

Deep flutes are a big deal on an auger bit this length. They pull chips out of the cut faster, which helps the bit stay moving in thicker stock and reduces the need to stop and clear packed debris. That matters when you are drilling repeated holes through studs or boring deeper passes where chip buildup can slow progress and heat up the bit.

The 7/16 inch hex quick-change shank is built for secure engagement in compatible cordless and corded drill drivers and impact-capable drilling setups. In practical terms, that gives you a more stable connection and quicker bit swaps when you are moving between drilling tasks. For anyone working overhead, on ladders, or moving room to room during rough-in, faster changes are not just convenient, they save real time.

At 13/16 inch diameter, this auger bit lands in a useful middle ground for trade work. It is large enough for many common pass-through applications without stepping up to a much heavier boring setup. The long body helps with access through thicker members and stacked material where a stubby bit comes up short.

This Diablo auger bit makes the most sense for pros and serious DIY users doing framing, electrical rough-in, plumbing rough-in, remodeling, deck work, and general construction. If your work involves drilling wood that may contain nails and you want a bit that cuts clean, clears fast, and holds up better than bargain bits, this is the right lane for it.
