Panasonic Cordless Power Tools are made based on these guidelines: cordless capability, power, lightweight, and ergonomic design. These tools can be used almost anywhere due to the cordless design. The Ni-MH battery charging system allows for long battery life and quicker re-charging time. Also, the cordless tools provide more than enough punch using high-power magnet motors, heat resistant brushes and built-in cooling fans. Ergonomic design means the tools are compact, well-balanced and easy to operate without fatigue. This 3.6V screwdriver easily converts from straight to pistol form for precise drilling. The change from forward to reverse is within reach of your thumb. To prevent over-tightening, it has auto shut-off and a two-speed gearbox. Spend more time working with the 3.6 battery. It can be fully charged in 15 minutes . minimize
