Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Irwin 13/16 in. D x 7.5 in. L Auger Bit Carbon Steel is built for serious woodworkers who require deep, clean holes with lasting durability. Crafted from carbon steel and heat treated for enhanced hardness, this auger bit is ready to handle demanding woodworking tasks.

  • Diameter: 13/16 in
  • Length: 7.5 in
  • Shank: 5/16 in hex shank
  • Material: Carbon steel
  • Usage: For wood
  • Heat treated: Yes
  • Packaging: Carded
  • Number in package: 1

The 7.5-inch length provides reach for deeper holes without frequent re-positioning, while the 13/16-inch diameter handles larger openings in wood projects. The hex shank improves grip and stability in compatible drills, helping prevent bit slip during heavy drilling. With heat-treated carbon steel, this auger bit stays sharp longer and stands up to repeated use in hardwoods and softwoods alike.

Who it's for

Ideal for professional carpenters, cabinet makers, and dedicated hobbyists who need reliable, large-diameter holes in wood—whether assembling furniture, installing dowels, or branching into deeper hole requirements. This single unit is a versatile addition to any drill kit, ready to tackle demanding projects straight from the box.

How it compares and practical notes

Compared to lighter-duty wood bits, this auger bit delivers cleaner exits and greater stability when drilling larger holes. The combination of carbon steel construction and heat treatment translates to longer service life under regular use, making it a practical upgrade for shops that value consistency and longevity in their tooling.

Tip: Use with a drill that accepts hex shanks for secure bit engagement, and apply steady pressure to maximize the bit’s performance and minimize tear-out in varying wood densities.
