Hitachi G18DL 18-Volt 4-1/2-Inch Lithium Ion Disc Grinder
Hitachi really knows how to build convenience into their power tools. At only 4.2 pounds, this grinder is the lightest on our list and runs at 9,200 rpm, making it the second fastest model of these five picks. The side handle can be attached in either of two positions, a slide power switch with a lock button for safety and also includes over-torque protection circuitry with a safety reset. Even better, this grinder will not only take Li-Ion batteries, but all Hitachi rechargeable batteries including Li-Ion, NiCad and NiMH. The included charger will also charge all those battery types, not something commonly found with cordless tools. Finally, the carbon brushes on this unit are easily accessible for rapid repair.
