HiKOKI Rotary Hammer Drill 40mm AC Brushless SDS MAX V/Spd UVP -DH40MEY2(G1Z)

Highest Demolition Performance and Fastest Drilling Speed in its class.  Industry first AC Brushless Motor. Unique Maintenance-free Brushless motor provides significantly longer life.  No carbon brush replacement required.  None of the traditional problems from conventional brushed commutator motors.Stable Performance under voltage drop situations. Unlike conventional electric Rotary hammers, drilling performance isn't affected as much by voltage drop from long extension leads on site.Example: 100mm extension load, 2.0mm² conductor. Performance of conventional models drop by approximately 14%, new Brushless models decrease by just 3%.Stable Performance when used with Generators. Brushless design operates consistently and without the traditional problems cause by generator use. Requires suitably sized Generator output.
