With a 28V motor and M28 Lithium-ion battery (sold separately), the 0725-20 delivers the speed (8,000 RPM) and power needed for fast grinding and cutting applications with longer run time. The overload protection and soft start features extend tool life for extreme durability, and at only 6.8 lbs., the 0725-20 provides a compact, lightweight solution without surrendering features or durability. A large spindle lock provides quick wheel replacement and a five-position tool-free guard aids in easy guard adjustment. A slide-on switch and an ergonomic side handle provide more control, and reducing user fatigue. A built-in fuel gauge indicates remaining run time to eliminate having to guess how much charge is left in the battery.
