LED light and LED battery indicatorThe charge level indicator is represented as an indicator LED. There are several types of battery protection: from recharging and overheating, from overload and short circuit. The battery shuts off automatically when the maximum charge level reached. Thus, the cordless drill has a lot of advantages. Firstly, the cordless tool is truly universal. Secondly, its compactness and mobility are convenient for dismantling and assembling structures in cramped places. The presence of an indicator on the battery will not catch you unawares and an excellent selection of bits and drills will replace the heap of a conventional instrument.HAMMER FUNCTIONAHammer drill, when equipped with a masonry bit are designed for drilling into stone, concrete, brick or mortar. When a hammer drill operates it rotates like a normal drill as well as has a forward, hammering, type action. In order to drill a hole not only in wood and metal but also in brick and concrete, in addition to rotational movements, progressive percussion is necessary. The impact is designed to crush the material, while drilling extracts the crumbs outward and helps the bit to bite into the material. That is, for effective drilling of solid materials, it is necessary that rotational and shock motions occur simultaneously.
