The Irwin 87910 Speedbor is a wood boring spade drill bit designed for precision drilling in tight spaces and confined locations. Its compact 4-inch overall length makes it ideal for drilling between wall studs, ceiling rafters, inside cabinets, and other areas where longer bits won't fit. The 5/8-inch diameter hole size suits standard wood dowels, conduit installations, and hardware mounting applications.

This spade bit features a flat flute design with a reinforced point and cutting edge that minimize wobble and deliver straight, clean holes. The grooved hex shank fits all standard quick change chucks and drill bit extensions. The double cutting spurs scribe the outside of the hole to reduce breakout, while the blue groove point and cutting edge enable faster chip removal.
