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

Introducing the Diablo 1-1/8 in. x 5-1/8 in. L Steel Self-Feed Bit with Hex Shank — a purpose-built solution for fast, clean holes in wood. If you’re tackling cabinetry, framing, or DIY projects that demand larger-diameter holes, this bit is designed to deliver reliable performance from start to finish.

What makes this self-feed bit unique

  • Self-feed design pulls itself into the material, helping to reduce wandering and binding so you can drill more consistent holes with less effort.
  • Hex shank (7/16" diameter) provides a secure, slip-free grip in drill chucks and is well-suited for use with impact drivers, letting you tackle tougher materials with confidence.
  • Solid steel construction delivers durable, long-lasting performance for repeated projects and busy shop-time.
  • Precise dimensions — drill diameter of 1-1/8 inch, overall length of 5-1/8 inches, and shank diameter of 7/16 inch ensure you know exactly what you’re working with for planning and fitment.
  • Protective packaging — packaged in a sturdy tube to protect the bit during storage and transport.

Ideal uses and practical tips

Designed for wood, this Diablo self-feed bit excels when you need large, clean holes for wiring, dowels, pipe fittings, or venting. It’s particularly effective in softwoods, plywood, and many soft hardwoods where quick hole completion matters. To get the best results:

  • Secure your workpiece and use a steady feed rate to maximize the self-feeding action.
  • Let the bit do the work; apply even pressure and avoid forcing it into knots or nails to prevent dulling or binding.
  • Use in a drill or driver with adequate torque to maintain a smooth cutting action without stalling.
  • Deburr the hole edges after drilling for a clean finish, especially for visibility or assembly purposes.

Who benefits most

  • Professional carpenters and cabinet makers who need quick, consistent large-diameter holes.
  • DIY enthusiasts tackling projects like furniture assembly, shelving, or wire management in wooden structures.
  • Workshop setups where reliable, repeatable performance and clean cuts save time.
