This is a tool for use in model assembly.
Here's a handy-dandy cordless electric screwdriver from Tamiya! Featuring a 21-step auto-stop torque clutch and two speeds, this set includes a rechargeable lithium ion battery and 100V AC charger. Also included is a nice soft case and 5 different bit attachments. Can be used in "pistol grip" form or "straight" form.
This item is designed to operate on Japan's 100V electrical system, so be sure your country's system is compatible before use. You may need to purchase a power convertor to use the 100V AC battery charger.
