The historical development and functionality of rotary hammers

Already since 1857, the first rotary hammers were used in tunneling and mining. These pneumatic versions were compressed air operated. These helpful machines were used with electrical energy from the end of the twenties. Only since the end of the sixties hydraulic rotary hammers are used. The modern rotary hammers work either on the electro-mechanical or electro-pneumatic principle. In the mechanical percussion power is transmitted to the drilling tool by means of a transmission device. The transmission in the pneumatic impact mechanism, the rotational vibrations of the electric motor to stroke movements of the piston are changed, which moves with a so-called bat in an air chamber. The backward movements of the piston create a negative pressure, whereby the racket is pulled backwards. During the subsequent forward movement, an overpressure between piston and racket is caused. The racket is pushed forward at a considerable speed. The resulting kinetic energy is transferred via the firing pin to the tool shank. Pneumatic rotary hammers therefore have a much higher impact force than mechanical versions. In addition, a sealing ring protects against dust and dirt in the interior. However, the performance advantage is also noticeable in the price.

Quality criteria and various uses

With a Rotary mallet is drilled in extra hard material. In contrast to a less efficient percussion drill on which the user has to exert pressure is sufficient for Rotary mallet the attachment to the drilling site. Unlike the impact drillmoves at one Rotary mallet only the firing pin and thus the drillin the drilling direction, but not the drill spindle. For one Rotary mallet speak some advantages:

High efficiency

drilling precision

clean borehole

Diverse possibilities of use for construction workers and do-it-yourselfers (mortise and chisel hammers)

Comfortable, safe working

Among the leading brands in rotary hammers include Bosch, Hilti, Black & Decker and Makita. Many rotary hammer models are currently available in the market. With a Rotary mallet Can be drilled and chiselled except in concrete and granite also in steel and hardwood. When buying a hammer drill, the following criteria should always be observed:

mass

noise

Ergonomically shaped soft rubber grip for easy handling and vibration isolation

energy output

Maximum drilling depth (in millimeters) and impact force

Transmission quality (single or dual gearbox)

Disconnectable hammer mechanism

Possibility to adjust the speed

Fast, uncomplicated drill replacement

Price-performance ratio

Features, advantages and disadvantages of the models offered

Material improvements, technical advancements and modern processing techniques result in the production of numerous high-quality rotary hammers. In addition to the consideration of general quality criteria, test results can serve as a selection aid for a purchase decision for a hammer drill. It should be noted that these evaluations are often used only to small differences as a basis for the formation of orders. Nevertheless, the test results provide valuable guidance, especially for prospective buyers with little background knowledge. The model PBH 3000-2 FRE from the manufacturer Bosch, for example, has been judged very positively in terms of the essential criteria. Special mention is made here of the functional exchangeable chuck, the two-speed gearbox and the extensive drill set. As a minor drawback, the slightly weaker depth stop was listed. With its simple design, the lighter model Makita HR 2470 of the Japanese manufacturer received good ratings. However, it has been found disadvantageous that the length of the work machine can lead to problems when working in confined spaces. The hammer drill Black & Decker KD960 KC, which has also been tested with good results, can easily solve all the work of do-it-yourselfers. At a much lower impact strength than the Bosch model, however, there are limitations in performing more demanding tasks. The Hilti TE 2-M model also received good ratings, especially for handling construction site work. Especially the Hilti scored the drilling results. The lack of a speed selection was criticized.
