The Lighted Cordless Power Precision Screwdriver, No. 502, from General (502) helps anyone who works with small parts and micro assemblies in low-light situations. Its torque drive generates 100+ rpm while a high-powered LED aims a white light directly on the work area. The pen-sized tool comes complete with six precision 4mm bits: Slotted: 1/16" and 1/8", Phillips: #0 and #1, and Torx: T5 and T6. A quick-change chuck enables effortless swapping between bits and accommodates all available standard-sized 4mm bits. The ergonomic rubber grip and ABS housing boost the tool's functional design.
