When choosing a hammer drill, it is very important not to confuse this tool with a percussion drill. Some believe that the latter (if it has a percussion mechanism) works the same way as a perforator. However, this is not quite true. Impacts during the operation of these instruments have different strengths and origins.
The drill works as a punch, and in the process, the gears of the wheels, which are called ratchets, are used. The punch is designed for drilling different materials. With it, you can transfer the force to the edge of the peaks, drills or blades, providing maximum impact.
However, before buying it is important to pay attention not only to this. It is also necessary to consider the frequency of impacts. Power is one of the main characteristics. Hammers are more powerful than electric drills. This is because drilling is harder than drilling. Experts advise making a purchase with an eye on the spindle speed. It can reach 1,500 rpm. But it is important to determine the manufacturer. For example, Whirlwind rotary hammers are very popular among consumers for the reason that they have a good combination of cost and quality.
