The Makita DHR400 is a cordless rotary demolition hammer with a 36v brushless DC motor with low maintenance and extended runtime and is powered by twin 18v LXT batteries. This is a 2 function machine with rotary hammer mode for masonry drilling up to 40mm and hammer only mode for chiselling.
AVT (anti vibration technology) reduces hand arm vibration allowing for sustained use and AWS (auto-start wireless system) which automatically connects to compatible dust extractors with Bluetooth. This unit has an impressive hammer action of 8.0J and drilling capacities of 40mm solid bit and 105mm core bit.
Other features include constant speed control to keep the motor speed constant under load, torque limiter to protect the user against "snagging" plus soft start, variable speed and electric brake.
