Real power

The power given out by the perforator directly to the drill or other working equipment. This figure is inevitably lower than the power consumption (see below) due to energy losses in the tool mechanisms.

In general, higher net power means more efficiency and productivity; the reverse side of these advantages is an increase in price, energy consumption, dimensions and weight (however, the latter is not always a drawback for rotary hammers). In addition, note that tools with similar useful power values may differ in the ratio of chiseling speed and impact power: remember, a higher frequency means less energy for each individual impact, and vice versa. So the big numbers in this paragraph can mean both high efficiency when working with hard, stubborn materials, and good performance on relatively simple tasks; these features need to be specified separately.

Also, by the ratio of useful and consumed power, one can evaluate the efficiency of the tool in terms of energy consumption: the lower the power consumption (with the same useful power), the more efficient this model is. The downside of energy efficiency is often increased cost, but it can be recouped fairly quickly in energy savings, especially if you work long hours and often.

Power consumption

Rated power consumed by the rotary hammer during operation. Usually, the maximum power consumption in normal operation is taken as the nominal power.

In general, the higher this indicator, the heavier and more performant the rotary hammer is, the more advanced its performance usually turns out to be. On the other hand, the electricity consumption of such tools is high. In addition, note that with the same power consumption, the actual set of individual characteristics for different tools may be different. For example, frequency and impact energy are inversely related, and for the same power input, higher frequency usually means less individual impact energy. So, according to this parameter, it is worth evaluating only the overall level of the instrument; for accurate selection for specific tasks, you need to pay attention to more specific characteristics.

Also note that power consumption data can be useful for some tasks related to catering — for example, if a construction site is powered by an autonomous generator and you need to estimate the load on this energy source.

Impact energy

The energy transmitted by the perforator to the material being processed upon impact; the higher this indicator, the stronger and more powerful each individual blow.

First of all, we recall that the energy of impacts is directly related to their frequency: an increase in frequency leads to a decrease in energy. Therefore, for models where the number of strokes can be adjusted, this paragraph usually gives the maximum energy achieved at the minimum speed of operation.

In general, higher impact energy improves efficiency when working with hard, stubborn materials, but requires more motor power (especially if it has to be combined with a high frequency). Therefore, it is worth choosing according to this parameter, taking into account specific tasks. So, for occasional use in everyday life, an energy of 2 J or less is enough, for home repair work of medium intensity, at least 3 J is desirable; a power of 4 J or more is already considered high; and in some industrial-grade perforators, this figure can reach 30 J.

Rotation speed

The speed of rotation of the working equipment provided by the rotary hammer. Usually, this indicates the speed at idle, without load; rated load speeds can be further specified in the characteristics (see below), but this is rare, and this parameter is still considered the main characteristic. It is also worth mentioning that in the presence of a speed controller (see "Functions"), the maximum speed value is given here.

When working in the main mode — drilling with impact — the rotation of the equipment is used mainly to remove waste from the hole, and the revolutions here are of no fundamental importance (they can be very low). Therefore, it is worth paying attention to this indicator mainly in cases where the rotary hammer is planned to be often used for conventional drilling, without impact. And here it is worth proceeding from the fact that high speeds increase productivity and contribute to accuracy when working with some materials, but reduce torque (compared to tools with the same engine power). So for heavy work with hard, stubborn materials, relatively "slow" tools are usually better suited.

Note also that drilling is not the main task of rotary hammers; therefore, their rotation speeds are noticeably lower than those of the same drills. On the other hand, in this case, low speeds are often compensated by powerful engines and high torque, which makes it possible to effectively drill holes...of a fairly large diameter, including using crowns.

Max. torque

The maximum torque developed by the rotary hammer.

Without going into too much detail, torque can be described as the working force of a tool. For drilling with impact, this indicator is not of fundamental importance — we recall that the rotation of the nozzle in this mode performs an auxiliary function, and the key parameters are the frequency and energy of impacts. But with traditional drilling, without impact, the torque directly determines the effectiveness of the tool. The higher it is, the more powerful the impact on the material being processed, and the larger the drilling diameter this model can provide. However tools with similar drilling diameter limits may differ in torque; in such cases, you should assume that more operating force requires a more powerful motor and affects the cost, but it contributes to reliability and provides additional guarantee in case of some abnormal situations.

Reducer

The reducer is a mechanism that transmits rotation from the tool engine to the chuck with equipment. This reduces the speed of rotation, but increases the torque.

The simplest modern gearboxes are single-speed, with a constant gear ratio. They are standard equipment for modern rotary hammers, are used in the vast majority of models and have no special features worth mentioning. Therefore, in our catalog, the type of gearbox is specified only if it is a more advanced two-speed gearbox, with two gear ratio options (and, accordingly, two speed modes of rotation of the cartridge). Such mechanisms are more complicated and more expensive than single-speed ones, however, they provide additional features for customizing the punch to the specifics of the situation. So, at low speed, maximum torque is achieved, which allows you to effectively cope with hard materials; and if the material is relatively soft and the resistance is low, you can switch the gearbox to higher speeds, achieving greater performance.

At the same time, it is worth noting that the advantages of two-speed gearboxes are relevant mainly for drilling without impact, which in general is not the main task of rotary hammers. Therefore, there are few tools with this feature.

Wood drilling max. ⌀

The maximum diameter of a tool that can be used with a rotary hammer when drilling in wood (and, accordingly, the maximum diameter of the resulting hole). With a large drilling diameter, the loads on the device increase, and some models may simply not be designed for them (despite the technical possibility of installing tools of the appropriate diameter), as a result, it is not worth exceeding the maximum specified diameter, because. this may damage the instrument.

Concrete drilling max. ⌀

The maximum tool diameter that can be used with a rotary hammer when drilling in concrete. See "Maximum drilling diameter in wood" for details.

Max. hole saw ⌀

The maximum tool diameter that can be used with a rotary hammer when drilling with a hollow core. Crowns are used to create holes of large diameter (from 40 mm) in hard materials such as reinforced concrete and stone. See "Maximum drilling diameter in wood" for details on the maximum diameter.
