Makita DHR400ZKU Twin 18v SDS MAX Rotary Demolition Hammer With AWS Body Only In Carry Case

Makita DHR400ZKU Twin 18v AWS Brushless Cordless 40mm SDS MAX Rotary Demolition Hammer Body Only in Carry Case

The DHR400ZKU LXT Brushless and Cordless SDS-MAX Rotary Demolition Hammer has a 2-mode operation with rotational hammering and hammering only. The speed of the machine is automatically reduced at zero load to further reduce vibrations and to facilitate the targeted positioning of the chisel. Features include a one touch sliding chuck for easy bit change, a torque limiter to protect the user from snagging, electronic speed control with constant speed to avoid stalling under load and soft start to make the user experience more comfortable. “Soft No Load” reduces vibration of the tool body when idling which results in decreased vibration to the operator’s hands and also minimises deflection when lining the bit/chisel.

This model is also a part of the Auto-Start Wireless System (AWS) range, which can connect to compatible dust extractors with Bluetooth using the supplied Bluetooth adaptor. The dust extractor automatically runs while the tool is switch is on, and turns off when tool is off. This maximises the battery life of both products.

FEATURES
