Drill without exaggeration can be called an indispensable tool for both a professional master and an amateur owner. To hang a picture, collect and disassemble furniture, attach a cornice or a shelf, all these operations to perform without a drill are almost impossible.
Having a high-quality tool at hand, it is easy:
- Perform holes in concrete, brick walls, in wooden surfaces;
- Twist and twist the screws;
- drill the right-sized holes in metal products;
- Perform minor furniture repairs.
The modern market of tools designed for construction and repair is saturated with a variety of models – it is not surprising that it is difficult for the commoner to understand the intricacies of choosing a suitable model.
The question is, which drill to choose? What to pay attention to when buying, so as not to regret the money spent?
Drill, screwdriver, or punch?
These tools are similar in appearance, but they are designed to solve fundamentally different problems and often cannot be interchangeable. The main difference is in their main function:
- The shurovert is designed to twist and twist self-cutters, screws, screws, make holes;
- The drill gives rotational motion drills to make holes in metal, wood, plastic;
- In the punch, the working part performs not only rotational but also shock-progressive movements.
Let’s dwell in more detail on the varieties of drills. There are impactless and percussion models. The first is small in size and is used to perform precise work, for example, for drilling neat holes.
Shock instruments are larger in size and more powerful – they can be considered a hybrid of hitless models and perforators. The main difference is the presence of a drilling mode with a blow. Thanks to this, such drills can cope with more complex tasks, for example, drilling holes in dense concrete, brick wall, stone.
There is a reasonable question, how does the shock drill differ from the puncher. Technically, both tools can handle most of the tasks. However, there is a difference – it lies in the functionality of the tools. The drill is hit mechanically, the puncher – with the help of pneumatics. Besides, the punch is always larger, heavier, and more powerful.
It should be understood that the main function of the drill is the drilling of holes, and the punch is designed to destroy the structures, so neat types of work with high accuracy “can not.”
What are the varieties of drills for the purpose?
Besides shock and hit-without-impact drills, manufacturers produce the following performances:
- Drill-screw is light, practical, easy to use, has a reverse function;
- The battery drill is convenient because it is not tied to the socket;
- the angular drill is a highly specialized tool, usually not used in everyday life;
- The drill mixer is a powerful impactless model that can mix building mixtures of varying viscosity.
What is the difference between professional models and everyday models?
Many tool manufacturers divide the units produced into professional and household units.
In terms of functionality, they are the same; the difference is like use. Professional models are designed for frequent or continuous use; they have an ergonomic design and a narrower specialization. You can work with this tool all day long without worrying about its resource.
Another important parameter is performance. In professional units, it is higher. Among the professional drills, there are models with a reinforced hull designed for intensive operation.
To perform various tasks to repair the house, in the garage, in the country is quite possible to do household varieties. If you choose the right model on the price-quality ratio, then such a drill will justify its purchase cost.
Household drills in power and other parameters may not yield to professional counterparts. But it can not be operated in a constant mode – every 15-20 minutes, the tool should be allowed to cool down. That is, in other words, how many drills worked, the same amount of time it needs for it to “rest.”
If you follow the mode of operation of the device, not allowing overheating of the engine, the household drill will last a long time. More than 3-4 hours a day to use such a tool is not recommended. Otherwise, it will fail.
Some manufacturers offer intermediate group drills to consumers – these are the so-called Hobby-class (or semi-professional) models. Such drills exceed the price and technical characteristics of household varieties but are inferior to professional ones. They should pay attention to the owners of small workshops – here, the need to use a drill arises with a certain regularity, while the unit has time to cool down in between work.
Hobby-class tools differ:
- Good build quality
- Advanced functionality;
- good power parameters.
The power of semi-professional models can reach 1200 w; they can work up to 6 hours per day.
What is the difference between different models?
Both professional and household drills are produced in different versions: with one and two speeds.
If you need a tool for periodic use (to perform a few holes, mix a small amount of putty, or twist a few screws), a single-speed drill will cope with such tasks.
Drills with two speeds have advanced functionality; they easily carry serious loads. With them, you can do complex repairs. Two-speed models have a reinforced body and, as a rule, higher power. Some tools are electronically controlled, which makes it possible to use the device more accurately.
What specifications to pay attention to?
After studying the basic technical parameters, you will know how to choose a drill for domestic use without overpaying for unnecessary functions.
One of the main characteristics that determine the functionality of drills is power. The higher the figure, the wider the range of operations that a particular model can handle.
However, not always enough one power – you need to look at the device’s functionality as a whole. Typically, 750-900 w is enough for home use. The weight of such drills ranges from 2 kg to 6.5 kg—models with the higher power, heavier and larger, which increases the load on the hands.
Varieties with a capacity of 300-500 W cope with small volumes of work, can work for a short time. They can be used to drill small holes in soft materials. You need to consider the following point: if the model is chosen incorrectly, the hands will also get tired (not from the weight, but you will need to make additional efforts when working the tool).
Professional drillers have more power than 900 W (can reach 1.5 kW and above). Accordingly, the weight and dimensions of the instrument increase.
Next, you need to pay attention to the gearbox – a mechanism that transmits power by rotation. The type of gearbox determines the reliability of the drill and its practicality. There are one- and two-speed devices.
Additional links increase torque, a metric by which the tool can perform complex work and large volumes without serious loads. When choosing a household model, you need to pay attention to the material of the gearbox. It is desirable that it was made of metal or plastic with good heat conduction characteristics.
The next important parameter is the regulation of turnovers. The maximum number of hit-by-impact models is 2600-3000 rpm.
As a rule, shock drills have a higher number of turns than non-impact varieties. If you plan to use a drill with different nozzles (grinding, polishing), then the number of turns, in this case, will play a crucial.
Another important characteristic is the type of cartridge and the maximum drilling diameter. The last parameter should be taken into account not to burn the tool on the first day of operation. It is important to adhere to the parameters specified in the instrument passport.
Most often, in drills cam or fast-clamping mechanism of fixing the drill. In a traditional jagged cartridge, the drill is mounted with a special multi-faceted key. In a fast-pinching installation, the drill is manually rotated by the cartridge. In terms of fixing cam, cartridges are more reliable, but fast-clamping allows you to change the nozzles quickly.
In turn, fast-clamp cartridges are divided into one- and two-gig. A single-shell cartridge is the most convenient.
When choosing a drill, you need to consider the power of the shock function (for shock models). This figure is determined in joules. To make holes in a concrete or brick base enough shock force in 2 Joule. If you need a tool to break the walls under electrical wiring, you will need a power tool with more impact force. In professional models, this figure can exceed the value of 5 Joules.
The drill can be equipped with additional features. They make the job more comfortable. These include:
- reverse – the ability to change the direction of rotation (will be by the way when using a drill as a screwdriver);
- An additional handle – allows you to fix the tool more reliably.
- Deep-com- – allows you to adjust the depth of drilling accurately;
- Switch button blocker – prevents accidental pressing.
What’s better: a wired or rechargeable drill?
It is difficult to say that it is better. If you are wondering how to choose a drill for the house, first of all, decide what you need such a tool for.
Wired drills, working from the network 220 B, are reliable and stable – this is their plus. However, if the drill is needed in a room without wiring, you will need a model on the battery. The absence of the need to carry a carry significantly reduces the time it takes to complete the work.
If you want a wireless model, it’s worth a closer look at the sleeper with a replacement battery. While one, the other will be on recharging, which will eliminate downtime in work.
A wired medium-capacity model is quite suitable for relatively rare household work. If you plan to repair an apartment or a private house on your own, it makes sense to choose a rechargeable model with good performance. Budget instruments have lower not only technical parameters but also a resource.
In conclusion, I would like to note that it is essential to pay attention to the manufacturer. Some companies specialize in producing professional tools (for example, Dewalt); others – make the only household. Some brands produce different types of drills. Companies often label their tools in color:
- Bosh – in household varieties, the body is green, and professional – blue;
- Makita – models designed for domestic use, red, professional – blue.
- Black and Dec have a well-established household tool – they are produced in bright orange.
