Diablo FB-013 1-3/4 Inch Forstner Bit High Speed Steel Precision Wood Drilling Flat Bottom Holes 3/8 Shank for Drill Press Hand Drills

Heavy-Duty Precision Boring: Diablo 1-3/4 Inch High-Speed Forstner Bit

Master large-diameter drilling tasks with the Diablo FB-013 1-3/4 in. Forstner Bit, the professional's choice for boring clean, flat-bottomed holes in any wood species. While standard spade bits and hole saws often leave rough edges or blow out the back of the material, this premium bit utilizes a precision-forged high-speed steel construction to deliver furniture-grade results. Whether you are installing large architectural hardware, creating mortises for joinery, or drilling through thick beams, the ultra-sharp center spur ensures the bit engages exactly where you mark it, eliminating the risk of "walking" across your workpiece.

Engineered for durability and versatility, the FB-013 features a sophisticated double-ground serrated edge geometry. This design acts like a series of chisels, slicing through wood fibers cleanly to minimize splintering and chipping, even on difficult overlapping or angled cuts. The forged steel body is heat-treated to withstand the high temperatures generated by drilling large 1-3/4" holes, ensuring a significantly longer service life than carbon steel competitors. With a 3/8-inch reduced shank, this bit provides a secure grip in standard drill chucks, making it compatible with both benchtop drill presses and handheld power drills.

Key Features

• Precision Centering: Sharp center spur acts as a pilot to locate the hole center accurately, ensuring no bit walking or skating.
• Serrated Cutting Edge: Double-ground serrated edges shear wood fibers for smooth, splinter-free sidewalls and bottoms.
• Forged Durability: Hardened high-speed steel construction resists heat and wear for a longer cutting life.
• Versatile Application: Capable of drilling straight, angled, and partial overlapping holes in hardwoods, softwoods, and plywood.
• Universal Fit: 3/8" round shank fits securely in standard hand drill chucks and drill presses.
• Clean Finish: Produces flat-bottom holes ideal for large dowels, hardware recessing, and decorative work.

Specifications

Pro-Tip: Drilling a 1-3/4" hole removes a significant amount of material and creates high torque. Safety is key: If using a handheld drill, use a low-speed / high-torque setting and ensure you have a firm two-handed grip. Ideally, clamp your workpiece securely to a table to prevent it from spinning should the bit bind.
