Boorhamer Hikoki DV20VB2 WUZ 790W

The Hikoki DV20VB2 WUZ 790W perforator is a corded rotary hammer built for drilling and light chiseling in concrete, masonry and other construction materials. It combines a 790-watt motor with variable speed control and a quick-change chuck to support a range of drill bits and accessories. The tool's durable housing and ergonomic handle are designed for extended use on job sites and in workshop tasks where consistent power and reliable bit retention are required.

Advantages

The perforator delivers steady power from a 790 W motor and offers variable speed for precision when starting holes or adjusting to different materials. Its quick-change chuck enables fast swapping of bits without additional tools, while the reinforced construction increases resistance to wear during demanding applications. The ergonomic grip reduces operator fatigue during prolonged use and improves handling for both drilling and light chiseling.

Key specifications

How to use

Select the appropriate drill or chisel bit and insert it into the quick-change chuck according to the manufacturer's instructions. Set the variable speed control to a low setting when starting a hole, then increase speed as the bit progresses and material allows. For chiseling, switch to the chisel mode and hold the tool with both hands, keeping a firm but comfortable grip. Maintain steady pressure without forcing the tool; let the hammer action perform the work. Disconnect from the power source before changing accessories or performing maintenance.

Recommendations

For best results, use bits rated for masonry or concrete and wear appropriate personal protective equipment such as eye protection, hearing protection and dust mask. Match bit diameter and type to the application, and use lower speeds for larger diameters or fragile materials. Regularly inspect the chuck and housing for wear and clean ventilation slots to prevent overheating.
