The Hikoki DV18DCJRZ 18V Brushless Combi Drill is a versatile, all-round power tool that includes Reactive Force Control. Reactive Force Control RFC is a safety feature that When the gyroscope sensor built in the controller detects a predetermined angle, the motor stops automatically to prevent excessive jerking of the tool. The powerful brushless motor provides more energy and power generating a maximum 2000rpm no load speed, impressive max 140m torque and up to 30000bpm impact rate. Featuring 2 speedvariable speed including reverse, 13mm single sleeve keyless chuck for easy one-handed bit installationremoval, max drilling capacity up to 80mm into wood, 16mm into steel and 22mm into masonry making it ideal for use in a variety of materials as well as a wide range of applications. The LED job light for use in low visibility applications together with a variable speed trigger for greater control. The side handle can be mounted in 11 different positions to improve workability and due to the highly durable design that is resistant to heat generation, it is difficult to stop even during continuous work. At the heart of this tool is the brushless motor that allows you to use the drill efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
