The percussion mechanism is coarser than that of an impact drill and smashes the material in a stroke-like movement. With a rotary hammer - as the name indicates - the drill bit rotates while a percussion mechanism provides a hammering effect. In addition to how they work, the two types of tools differ in what they are suitable for and how much physical effort you have to put in. The Bosch Electronic Speed Control, an additional variable speed control system, is available for work on specific materials. Some rotary hammer drills even have a 2-speed gearbox to provide optimum control over speed and torque. Also, you’ll want to consider whether to buy a corded hammer drill or not. These include whether the tool has the ability to reverse the rotation direction (for unscrewing screws, for instance), and whether it can utilise the Bosch Vario-Lock for more liberal chiselling applications (as the chisel must not rotate when in use). In addition to these fundamentals, there are other factors that can improve the effectiveness of rotary hammers. A Bosch SDS hammer drill not only guarantees optimum power transmission, it also enables drill accessories to be changed quickly and without additional tools . Tool holder: Most modern rotary hammers are equipped with the SDS chuck developed by Bosch.An impact strength of 0.6J, for example, can penetrate concrete, but would not be sufficient for chiselling or drilling larger holes. Individual impact strength: This parameter indicates the energy with which the hammer drill "strikes".Impact rate: This indicates the speed and rate of a hammer drill’s percussive hits, measured in beats per minute (bpm).Bosch, for example, has electric hammer machines with 12-volt and 18-volt battery systems . In this case, the power is measured in volts. However, many DIY enthusiasts also enjoy using cordless hammer drills for everyday tasks. The lower limit for an electric hammer drill should be around 500-600 watts. In any case, a higher max wattage means the drill can last longer without overheating. However, this is not necessarily true for the power of a hammer drill, because it also depends on how the tool was constructed, and the quality of the parts used. In basic terms, the greater the watts, the greater the power. The best hammer drill machine for your needs will depend on how well these factors interact with and complement each other. However, make sure you don’t just focus on one or two aspects. The following criteria paint a picture of what you should be looking at when choosing a rotary hammer. The best hammer drill is one where the individual components work together in the best way possible. Before you make a purchase, you should consider include the weight, speed, drill chuck, rotation stop, impact rate, and individual impact strength of the hammer drill. Hammer drills vary in performance, ease of use, and quality.
