Precision Woodworking Excellence: Diablo 1-1/8 Inch High-Speed Forstner Bit

Experience the next level of drilling precision with the Diablo FB-008 1-1/8 in. Forstner Bit. Designed for professional carpenters and serious woodworkers, this high-performance bit creates perfectly smooth, flat-bottom holes that standard spade bits and hole saws cannot achieve. At the heart of its design is an ultra-sharp center spur that accurately locates the center of your hole, ensuring the bit starts exactly where you intend without "walking" or skating across the material surface. This makes it the ideal choice for intricate joinery, hardware installation, and doweling where accuracy is paramount.

Built to last, the FB-008 is manufactured from premium forged, hardened high-speed steel, providing a cutting edge that withstands heat and wear significantly longer than conventional bits. It features a unique double-ground serrated edge that slices through wood fibers cleanly, minimizing splintering and chipping even in delicate veneers or hardwoods. Whether you are drilling straight, angled, or challenging overlapping holes, the 3/8-inch shank ensures a secure fit in drill presses and hand drills, delivering consistent, high-quality results every time.

Key Features

  • Pinpoint Centering: Sharp center spur acts as a pilot to locate the hole precisely and prevent bit walking.
  • Clean Cutting Action: Double-ground serrated edges shear wood fibers for smooth, splinter-free holes.
  • Forged Durability: Hardened high-speed steel body ensures extended bit life and superior edge retention.
  • Versatile Capability: Effortlessly drills straight, angled, and overlapping holes in all wood types.
  • Universal Compatibility: 3/8" round shank fits securely in standard drill chucks and drill presses.
  • Smooth Finish: Produces flat-bottom holes ideal for mortising, pocket holes, and hardware recesses.

Pro-Tip: The 1-1/8" size is commonly used for latch bores on interior door knobs. When drilling through a door, drill from one side until the center spur just pokes through the other side, then stop. Finish the hole by drilling from the opposite side using that small pilot hole; this technique prevents "blowout" and ensures a clean edge on both sides of the door.
