The Diablo 2-1/8" Forstner Bit for Wood is a precision-engineered boring bit designed for woodworkers who need clean, flat-bottomed holes in hardwoods, softwoods, veneered plywood, and MDF. Built with high-speed steel and forged for lasting strength, this large-diameter bit handles straight holes, angled cuts, and overlapping bores with minimal splintering - making it a go-to choice for cabinetry, furniture building, and general woodworking. Whether you are working at a drill press or using a hand held drill, this 2-1/8" wood boring bit delivers smooth, professional results on every pass.

Key Features

• Drills straight, angled, and overlapping holes in all kinds of wood with minimal splintering - gives woodworkers versatility without sacrificing hole quality or surface finish
• Quality forged construction of high-speed steel for strength and extended life - means the bit holds its edge through demanding use and resists wear over repeated boring sessions
• Ultra-sharp center spur accurately locates the center of the hole and resists "walking" on material being drilled - results in precise hole placement every time without slipping or wandering on the workpiece
• Steep-angled, double-ground, razor-sharp serrated edges slice throughout the full rotation of the bit - reduces splintering and chipping at the hole rim for a cleaner finished edge
• Drilled holes are smooth and flat, and create chisel-like curls for fast, clean chip removal - keeps the work area cleaner and reduces the risk of clogging during deep boring passes

Why This Product

• At 2-1/8" in diameter, this Diablo Forstner bit handles large-diameter flat-bottom holes that standard twist or spade bits cannot produce cleanly - ideal for door hardware, shelf pin boring, and cabinet work requiring wide, smooth bores
• The serrated cutting edges and sharp spur work together to keep hole edges clean in sensitive materials like veneered plywood and MDF, where tear-out is a common problem with lesser bits
• Compatible with both drill press and hand held drill use, this bit adapts to your workspace without requiring specialized equipment - practical for job site and shop use alike
• The 3/8" shank fits a wide range of standard drill chucks, and the 3-1/2" overall length provides the reach needed for pocket holes and overlapping applications without excessive overhang

What shank size does the FB-016 Forstner bit use, and will it fit my drill chuck?

The FB-016 uses a 3/8" shank, which is a common size compatible with most standard drill chucks found on both drill press machines and hand held drills.

Can this bit drill overlapping or angled holes, or is it limited to straight boring?
