Diablo FB-006 7/8 Inch Forstner Bit High Speed Steel Precision Wood Drilling Flat Bottom Holes 3/8 Shank for Drill Press Hand Drills

Unmatched Precision for Custom Joinery: Diablo 7/8 Inch High-Speed Forstner Bit

Elevate the quality of your woodworking projects with the Diablo FB-006 7/8 in. Forstner Bit, a premium tool engineered to drill smooth, flat-bottom holes with exacting precision. Whether you are installing hardware, creating mortises, or drilling for dowels, this bit outperforms standard twist and spade bits by producing exceptionally clean holes without tearing the wood grain. The design features a razor-sharp center spur that precisely locates the center of the hole, preventing the bit from "walking" or skating across the material surface upon contact.

Built for durability and professional use, the FB-006 is constructed from forged, hardened high-speed steel, ensuring a longer cutting life and superior edge retention. Its double-ground, steep angled cutting edges act like a chisel to slice through wood fibers cleanly, while the optimized geometry ejects chips efficiently to reduce heat buildup. Capable of drilling straight, angled, and even overlapping holes without splintering, this 7/8-inch bit is compatible with any drill press or hand drill featuring a 3/8-inch chuck or larger.

Specifications

Pro-Tip: When drilling overlapping holes (such as when clearing out material for a mortise lock), always drill the outer holes first and the center connecting holes last. The center spur needs solid wood to engage; if you drill the center first, the bit will have nothing to grab onto for the subsequent overlapping cuts.
