Good uses for small cordless drills include making small or big holes, driving screws and bolts, and creating hidden, angled joints with a jig attachment. A sanding drum attachment is useful for sanding contours or curved surfaces, and a brush bit attachment helps remove rust from iron or steel tools.
A small cordless drill can twist wires or steel cables into a neat bundle by attaching the ends of the wires into the drill chuck and carefully spinning them together. Additionally, the low setting on a drill can act as a tool to straighten bent wires through slow rotation. Specialty mixing bits can turn the drill into a paint mixer or a mixer for concrete, grout or mortar.
