87916 Speedbor Spade Drill Bit, 1 In. X 4 In., Hex Shank

The Irwin 87916 Speedbor Spade Drill Bit is a compact wood boring tool designed to reach tight spaces where standard-length bits won't fit. Its 4-inch overall length makes it ideal for drilling between studs, rafters, and deep inside cabinets or wall cavities. The shortened profile reduces swing-out and gives you better control in confined areas, making it perfect for electrical wiring installations, plumbing runs, hardware mounting, and other applications where space is limited.

This spade bit delivers clean, straight holes in both hardwoods and softwoods while minimizing splintering and damage to surrounding materials. The grooved hex shank prevents slipping in your drill chuck or quick-change extension, ensuring reliable performance throughout the job. Whether you're a carpenter, electrician, or DIY homeowner, this bit reduces frustration by eliminating the need for awkward extensions or risky maneuvering in tight quarters.
