The Hikoki UV3628DAJYZ 36V MultiVolt Brushless Concrete Vibrator is a high frequency device that has been designed for decoration jobs. Now, before you go getting any ideasin particular, this is designed to help remove any trapped air bubbles when laying concrete. Yes, really. Having air bubbles in concrete foundations can increase the risk of foundation failure. The concrete vibrator lets you remove air bubbles before it sets thereby increasing the integrity of the concrete. The UV3628DA delivers two power vibrating modes with a top frequency of 15,200 movements per minute. Thanks to the 825mm flexible shaft, the vibrating poker can easily stretch across foundations and cover a larger area. This is further supported by the 28mm poker head. A switch-on lock ensures continuous operation without actuating the switch for fatigue-free work, while both battery and tool are protected against concrete ingress thereby increasing the life of the tool as well as reducing the effort to clean it. At the heart of this concrete vibrator is the brushless motor that allows you to use the tool 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.
