Diablo FB-012 1-5/8 Inch Forstner Bit High Speed Steel Precision Wood Drilling Flat Bottom Holes 3/8 Shank for Drill Press Hand Drills

Superior Boring Performance: Diablo 1-5/8 Inch High-Speed Forstner Bit

Achieve professional-grade precision in your woodworking with the Diablo FB-012 1-5/8 in. Forstner Bit. Designed to outperform standard spade bits and hole saws, this premium tool is engineered for drilling smooth, flat-bottomed holes with exceptional cleanliness. Whether you are boring large diameter holes for joinery, creating recesses for hardware, or drilling through-holes for plumbing and electrical rough-ins, the razor-sharp center spur ensures the bit stays perfectly centered without "walking" or damaging the workpiece surface.

Constructed from forged, hardened high-speed steel, the FB-012 delivers a cutting life that far exceeds that of conventional bits. Its advanced geometry features double-ground serrated edges that slice through wood fibers rather than tearing them, resulting in splinter-free holes even in difficult grains or veneers. The steep, angled cutters efficiently lift chips out of the hole to prevent overheating, while the 3/8-inch shank provides a secure, non-slip grip in both drill presses and handheld power drills.

Key Features

• Pinpoint Accuracy: Ultra-sharp center spur acts as a pilot to locate the hole center accurately and prevent walking.
• Splinter-Free Finish: Double-ground serrated cutting edges shear wood fibers for smooth, polished hole walls.
• Forged Durability: Hardened high-speed steel body ensures extended bit life and superior wear resistance.
• Versatile Application: Drills straight, angled, and overlapping holes in hardwoods, softwoods, and plywood.
• Efficient Chip Removal: Optimized geometry creates chisel-like curls for fast evacuation and cooler operation.
• Universal Fit: 3/8" round shank is compatible with most standard drill chucks and drill presses.

Specifications

Pro-Tip: As the diameter of a Forstner bit increases, the speed of the drill should decrease. For a 1-5/8" bit, run your drill at a lower RPM to prevent the bit from overheating and scorching the wood. If drilling deep holes, lift the bit out occasionally to clear the chips.
