Diablo 1-3/8 in x 5-1/8 in Steel Self-Feed Bit with Hex Shank is engineered to make large-diameter holes with confidence, delivering clean, precise cuts in a single pass. Built from durable steel, this self-feed bit is designed for dependable performance on demanding projects where speed and accuracy matter.
Key features that set this bit apart:
-
Hex shank for secure, slip-free operation: The 7/16 in hex shank provides a rock-solid grip in drill chucks and impact drivers, enabling quicker changes and reducing wobble during heavy drilling.
-
Self-feed design for faster hole entry: Engineered to bite efficiently and maintain steady progress, helping you drill large holes with less manual effort and fewer passes.
-
Precisely sized for versatile applications: 1-3/8 in drill diameter creates sizable openings for electrical, plumbing, or woodworking tasks, while the 5-1/8 in overall length gives you reach in deeper workpieces.
-
Rugged steel construction: Built to withstand repeated drilling in wood and similar materials, offering long-lasting performance and reliable hole quality.
-
Protective packaging: Shipped in a tube to protect the bit during storage and transport, ensuring it remains ready for the next project.
Why choose this Diablo self-feed bit over other options? The combination of a robust steel body, a hex shank for quick, secure engagement, and a dedicated self-feed geometry translates to faster results with less effort. It’s especially well-suited for carpentry, cabinet making, and rough-in tasks where large holes speed up cable runs, conduit passes, or hardware installation.
Practical use scenarios:
- Routing large holes in wooden frameworks for wiring, plumbing, or ventilation runs.
- Creating door hardware openings or clearance holes for fixtures where clean, round cuts are essential.
- Workbench and shop projects that require precise, through-hole drilling without bogging down the drill.
Tips for best results:
- Use a steady, controlled feed and moderate RPM to prevent bit binding and overheating.
- Keep the workpiece perpendicular to the drill axis to ensure a clean, true hole.
- Let the bit do the work—avoid applying excessive pressure that can dull the cutting edge or stall the drill.
Ideal for professionals and DIY enthusiasts alike, this Diablo self-feed bit is a reliable addition to any drill kit when you need large, clean holes fast. Add it to your cart for immediate use in woodworking, rough-in projects, and other applications that require precise, sizable openings.
