Panasonic ideas for life. For two decades, Panasonic has been building cordless tools and components. The company's Predator cordless drills and Hyperformance tool series spread quickly from industrial users to serious hobbyists. The advanced technology and competitive prices of these award-winning tools make them a top pick of the professional and homeowner alike. A leader in NiMH (nickel metal hydrite) battery technology, Panasonic batteries are interchangeable within the same voltage. They're also environmentally friendly and give more run time than ni-cad batteries. Panasonic cordless tools feature a high-inversion charging system, planetary gearing, and speed control via a unique feedback switch.
