I don't know how to take the 6V cordless screwdriver apart because there are no screws holding the orange body together. If I take the metal "U" shaped pin out, I see a two-stage planetary gearbox. I tried to search the Internet but I can't find anything about the Black & Decker AS6NG 6V cordless screwdriver. I found out that there is Black & Decker AD600 screwdriver with more torque. Both screwdrivers spin at 130 RPM. My Ryobi P200 cordless drill runs up to 1300 RPM and has 400 in.-lb. of torque. Any suggestions?
