The Diablo DAG1110 7/8 in. x 7-1/2 in. Auger Bit for Wood & Nail-Embedded Wood is built for boring fast, clean holes in framing lumber, rough wood, and wood that may contain nails. This is an auger bit designed for drilling clean, controlled holes in wood and nail-embedded wood. Model Number: DAG1110. If you need a bit that can handle real jobsite material instead of perfect shop stock, this is the right type of accessory.

What makes this bit useful on the job is the way its cutting geometry works together. Diablo uses a two-step cutting action to help start the hole cleanly, while the self-feeding Dura-Tip pulls the bit forward as you drill. That means less fighting the tool, more consistent feed, and smoother boring when you're running holes for rough carpentry, remodeling, or general construction work.

This bit is specifically aimed at wood drilling where hidden fasteners are part of the reality. The dual cutting edge design is meant to keep the cut moving smoothly in both standard wood and nail-embedded wood. That matters when you're boring through existing framing, older lumber, or jobsite material that is not always clean. Instead of treating nail contact like an immediate deal breaker, this auger bit is built for that kind of abuse.

Chip removal is another big part of how well an auger bit performs, and Diablo addresses that with deep flutes. In practical terms, deep flutes help move chips out of the hole faster, which keeps the bit cutting instead of packing up. That helps with hole quality, reduces drag, and can lead to more holes per battery charge when you're running cordless tools.

The 7/16 in. hex quick-change shank is a smart fit for real-world use. It is designed to increase stability and durability in cordless and corded impact wrenches and drill drivers, and it also speeds up bit swaps when you're moving between diameters or jumping from boring to fastening. If you work out of a pouch and do not want to waste time messing with a loose bit connection, that shank style is a real advantage.

In terms of size, this Diablo auger bit gives you a 7/8 in. hole diameter, a 7-1/2 in. overall length, and a 5-1/2 in. working length. That combination makes it a practical choice for common wood boring tasks where you need enough reach to get through framing members without stepping up to an extra-long ship auger.

Who should buy it? Contractors, remodelers, framers, electricians, plumbers, and serious DIY users who drill through structural wood and cannot always count on clean material. If your work involves boring holes for pipe, cable, conduit runs, or general framing access, and especially if nails are part of the job, the Diablo DAG1110 7/8 in. x 7-1/2 in. Auger Bit for Wood & Nail-Embedded Wood is a solid pick.
