About power tools

Power tools encompass a broad range of portable, motorized devices designed for material removal, fastening, and cutting operations. This category includes drills and drivers for rotary action and torque application, grinders for abrasive material removal and surface finishing, saws for precise material separation, and rotary tools for intricate work. Key variants include cordless drills with varying voltage ratings (e.g., 12V, 18V, 20V MAX) and chuck sizes (e.g., 3/8", 1/2"), impact drivers characterized by their IPM (impacts per minute) and torque output, and angle grinders specified by disc diameter (e.g., 4.5", 5", 7") and motor power. Saws are differentiated by blade type (e.g., circular, reciprocating, jig) and cutting depth. Rotary tools are often characterized by RPM range and collet size. Performance is primarily defined by motor power (watts or horsepower), no-load speed (RPM), torque (Nm or in-lbs), and battery capacity (Ah) for cordless units. Materials and finishes typically involve high-strength plastics for housings, hardened steel for gears and chucks, and various abrasive compounds for cutting and grinding accessories.

How to choose

When selecting power tools, first determine the primary application: drilling/driving, cutting, grinding, or fine detail work. For drilling and driving, consider the required torque and speed; cordless options prioritize portability, while corded units offer sustained power. Next, assess material compatibility and required cutting/grinding depth or diameter. Saws are specialized by material and cut type. For grinders, disc diameter dictates capacity. Finally, evaluate power source requirements: battery voltage and capacity for cordless tools, or wattage for corded models. Consider ergonomics and weight for prolonged use, and ensure compatibility with existing accessory ecosystems if applicable.
