What is it like?
The device of a shock drill is to transfer two ratchets to a drill immediately and rotate, and strike. The only disadvantage in this principle is the small amplitude of the impact, because of which it is necessary to exert great efforts, that is, to pressure the drill. This gives a strong vibration to the operator, and he quickly tires. To make this work easier, it is recommended that you select a powerful tool. Power varies between 400-1200 watts. The rotation speed can reach 3500 rpm, and the higher this speed, the correspondingly, the operation is easier.
Note! For long drilling, models with a trigger lock are released, which frees you from constantly pressing the trigger.
Some drills have a reverse function. This option allows you to rotate the bit in both directions, which is very useful if you need to remove the jammed drill or screw. The drill electric shock can be issued with the adjustment of the speed of rotation. There are models in which this process is regulated mechanically, by force of pressing, but more expensive devices maintain the necessary speed, thanks to electronics. Also, many models are available with a choice of speeds, which reduces the load on the tool and makes the work more rational.
Drill shock, how to choose correctly?
The choice of the drill starts with the definition of the tasks that you put before the tool. You should make sure that this or that drill is suitable for the work for which it is bought. For example, you need to make a hole in concrete or stone, then you need a device with increased power. Such tools can provide the necessary power, only working from the network, so the battery tool is no longer suitable. If the work is supposed to have softer materials, then the power of the device can be less, and, as an option, you can consider the unit with a battery.
Note! A drill on the battery pack gives the operator mobility and freedom in work.
For the correct analysis of all parameters and choice: the drill, which is better, the following points should be considered:
- Each drill has its own load limit and a temporary work rate. If this load exceeds the capabilities of the tool, it will quickly become unusable;
- You should analyze the goals of acquiring a shock drill, after all, a simple tool may suffice for your tasks;
- Quality of drill bit. It should be even, strong and resistant to heavy loads.
Impact drill or puncher?
Even the best impact drill is not always suitable for some tasks, such as deep drilling in superhard rocks. For such purposes, a perforator should be used. In this regard, again, it is necessary to very clearly imagine why you need a tool. Consider the possibilities of an impact drill and a perforator.
We already spoke about the characteristics of the percussion apparatus, let's see what can be squeezed out of it. Technical data drills allow you to drill metal, wood, masonry, and the most powerful aggregates can cope with concrete and stone. With the function of reverse, you can twist and unscrew the screws and screws. Also, having special nozzles, you can use an impact drill, like a grinder and a grinder.
The weight of this tool reaches 3 kilograms at the highest power, which is clearly not enough to work with very strong materials. Now let's evaluate the possibilities of a puncher. Their power ranges from 800 to 1500 watts at a weight of 2-11 kilograms. It is much more massive, has a special cartridge and tooling.
It is great for making holes in reinforced concrete and stone, and, if necessary, can even act as a jackhammer. Due to its design features, the perforator travels much faster into the material. During operation, there is no need to pressure the device. In the case of a puncher, the expression "like a hot knife in oil" is perfect. Note! The puncher is not capable of performing some of the functions of a drill, it's worth taking into account.
