A hammerless drill is equipped with a mechanism of the same name and is designed to work on soft materials, such as wood, plastic, soft metals. Existing models may differ in parameters and features, such as the power of the equipment (which can be from 240 to 1500 watts), the maximum diameter of the resulting holes and the maximum possible torque.

The torque in such a device will depend on the electric motor, through which the rotor drives the gearbox with the spindle, increasing or decreasing the speed. This tool may have a motor cooling option. The drills themselves are fixed in a chuck fixed on the spindle. The start of the drill is made by pressing the switch, with the help of which the speed of the output revolutions is simultaneously regulated. The chuck in which drills (or other work items are fixed) can be tightened through a key or be quick-clamping. Non-impact drilling tools are used for high-precision drilling, and in order to maintain the efficiency of the electric motor, they are not recommended for processing ultra-dense materials. It is this quality that impact models are superior to non-impact ones, overcoming the density of entry into the surface with the application of a sharp impact force.
Impact and non-impact samples differ from each other in the following parameters:
The more powerful this element, the longer and more intense the device is able to work and the greater the density of the obstacle it can overcome. The device with a powerful motor can safely process heavy structures and work for a long time without the need for technical breaks. The speed of rotation and the price of the product also depend on the power of the engine.In principle, even for domestic work, it is better to choose models with a powerful motor, because the range of tasks can be difficult to predict. However, a powerful tool can be quite heavy. For example, when assembling furniture or when performing repairs at home using a drill, you can feel the load on your hands from a heavy tool very quickly. Thus, the model should be selected based on the ratio of weight and power. For shockless equipment, the power can be from 250 to 1500 watts. Household battery options have power from 550 to 850 watts. In cases where the tool is selected for domestic rather than industrial needs, it is quite possible to get by with a compact and not very powerful product. They can work up to four hours a day, but technical breaks will be needed after every 20 minutes of continuous work.
The more revolutions the drill makes per second, the more intensive the drilling process is. If you need to make many small holes in the process of working with different simple materials, then high speed will be preferable. The rotational speed in hammerless drills is from 2500 to 3000 rpm. Of course, the higher the speed, the better, but there are situations in which it is necessary to reduce the speed, which can be done by using a speed controller.
In order to extend the life of the electric motor, do not violate the operating conditions recommended by the equipment manufacturer. The instructions, as a rule, indicate the maximum dimensions of the drills used and their purpose for surfaces of various densities.An unsuitable drill diameter and high material density will increase the load on the electric motor and may damage it. Torque parameters are also important, on which the screwing of screws into materials of various densities depends. At the same time, it is worth mentioning that if a drill is purchased for mixing building mixtures, then models with a higher torque should be used.
In fact, they can be intended for professional, systematic and domestic use, taking into account the frequency of equipment loading.
This type is not necessarily used only in industrial production and purposes - it is quite possible for home use in the production of large-scale work, and not just isolated cases of furniture assembly. It is quite possible to use in the process of building summer cottages or constructing outbuildings, major long-term repairs, during which the processing of concrete surfaces will be required. Professional drills have great power and can withstand intense and prolonged loads. Such models can work for 10 hours without risking damage to the main operational units or the electric motor.
Such equipment is not able to withstand very intensive work or work with ultra-dense materials. However, it has its own advantages, such as: ergonomics, due to their small mass, they are quite simple and easy to hold in your hand, and they are much cheaper than a professional tool. Different types of such tools include battery models and models that work from the network. Each such option is intended for its own work tasks.At the same time, the strength and durability of the equipment will directly depend on the quality of the assembly, including the professionalism and skill of the operator.
Most hammerless drills are powered by the mains and connected to an outlet. They need a stable supply of electricity, because if power fluctuations occur, the equipment may fail. During the acquisition of such a drill, it is better to take care of buying a stabilizer ahead of time. The advantage of these samples is the absence of the need to charge / replace batteries, and the disadvantage is the impossibility of using the device in places where there is no electricity supply.
The drill, which uses batteries, is quite mobile, it is convenient to work with it on the street and in places where there is no power supply. A charger is usually supplied with the device. It is better to have two batteries in the set at once, so that when one is charging, the second one could be used. Despite some limited power, cordless drills are capable of delivering high speeds. For the greatest comfort of work, they are equipped with a reverse rotation mechanism (reversible function), which makes it easy to screw in / unscrew various fasteners.
Hammerless drills can be equipped with three types of batteries:
In addition to their direct purpose - drilling, unstressed samples have various additional functions. As a rule, they greatly affect the price limits of devices, so before buying, you need to decide on their need. Additional options include:
IMPORTANT! Always remember that non-impact drills are not intended for processing reinforced concrete and do not have a chiseling function! Their working mechanism is not designed for such operations!
For successful work with an unstressed tool, you should follow a few simple rules:
