The General Tools 500 is a pen-size, cordless power precision screwdriver running on 3V DC from two AAA alkaline batteries (included). A geared micro-torque motor turns the bit at roughly 100 RPM, with a forward/reverse switch and a quick-change chuck that lets the user swap bits without tools. The handle is ergonomic with a cushioned rubber grip and supports multiple grip positions, and the whole tool weighs only 68 g (2.4 oz) with batteries installed.
Electronics technicians, computer and printer repair shops, office equipment and small appliance repairers, and hobbyists rely on the 500 wherever the job involves many tiny screws in tight spaces. Manufacturer applications include electronics repair, model building, and watch and jewelry repair. Driving small fasteners by hand is slow and tiring over a full repair session, and a powered driver reduces that hand strain. The torque is intentionally low, with a listed maximum of about 2.43 in-lb, so the tool is built for delicate fasteners rather than heavy tightening.
Common configuration: 3V DC supply from 2 x AAA alkaline batteries, 103 RPM no-load speed (±10%, marketed as 100+ RPM), about 2.43 in-lb maximum torque (±10%), 7-3/4" overall length, and a quick-change chuck that accepts micro (4 mm) bits. The kit includes six standard 4 mm precision bits: Phillips #0 and #1, slotted 1/16" and 1/8", and Torx T5 and T6. One distributor lists a hard rubber bit organizer in the package. The manufacturer cites 10+ hours of power from a set of batteries (some distributors list 8+ hours), and the tool carries a 1-year warranty. A replacement bit set is sold as the #500B.
