Power tools are electrically or battery-powered implements that perform cutting, drilling, shaping, fastening, and finishing operations. On homesteads, power tools reduce labor time for construction, fabrication, and maintenance tasks. The choice between corded and cordless tools depends on the mobility requirements and the intensity of use.
Drills are the most commonly used power tool. Cordless drills with 12 to 20 volt batteries handle most homestead tasks. Impact drivers provide higher torque for driving screws and lag bolts into dense materials. Circular saws make straight cuts in dimensional lumber, plywood, and sheet goods. Reciprocating saws (Sawzalls) are used for demolition, pruning, and cutting plumbing.
Angle grinders are used for cutting metal, grinding welds, sharpening tools, and surface preparation. Common disc sizes are 115 and 125 millimeters. Belt sanders and orbital sanders are used for wood finishing.
A table saw is the centerpiece of a woodworking shop for ripping and crosscutting lumber. Miter saws produce accurate crosscuts and angled cuts. Band saws cut curves and resaw lumber. Joiners and planers dress rough lumber to finished dimensions.
Power tools require eye and hearing protection. Loose clothing and long hair must be secured. Each tool should be inspected before use for damaged cords, missing guards, and proper operation.
