The hammer drill is one of the most essential tools for home renovation or construction. It can withstand loads, thereby facilitating the work associated with drilling, chipping or chiselling surfaces from various materials. Similar devices in a wide range are presented in hardware stores.But how to choose a good and convenient rotary hammer? To find a quality product, you need to understand how it works and how it works. RThe editors of the site "bestx.htgetrid.com/en/" prepared recommendations for you on the selection of these tools and made a rating of the best rotary hammers for 2019.
Attention! The ranking of the best rock drills for 2020 can be studied here.
What are they?
Here, the types of rock drills are described according to individual criteria. Recommendations for its use are also given.
By weight and application
By weight category and application, one can distinguish:
- Lightweight (household) - 2-4 kg: Devices that weigh less than 4 kg are considered simple. They are bought, as a rule, in order to make repairs at home or in the garage. These are ordinary household rotary hammers.
- Medium (for novice builders) - 5-8 kg: They differ in power and impact force - 5-7 J. Cuts even iron grating and concrete.
- Heavy (professional) - 8-10 kg .: Heavy specimen, which weighs more than eight kilograms and impact force - 8 J. Designed for long and continuous work. The tool is considered professional, which is why it is popular in construction crews. Buying a heavy hammer drill for household needs is a waste of money.
What is it used for?
The hammer drill is best suited for drilling concrete with a drill or bit. Of course, by choosing a model with the appropriate functions, you can deal with gating, destruction and other matters. And by putting on the adapter and turning off the blows, the device is able to drill through wood, metal or plastic.
But whatever the capabilities of the device, it is still better to choose a device with functions that are really necessary for the master. Because all the additional options (concrete destruction or vacuum cleaner) double the price and often reduce the efficiency of the main purpose.
How to choose?
Here are some tips on what to look for when buying a rock drill. In order to avoid mistakes when choosing, it is necessary to take into account a number of the following features.
What do you need to know about the design?
When choosing this tool, you need to consider several criteria:
Power
- Lightweight - 700 W;
- Medium - 900 W;
- Heavy - more than 1000 W.
Impact strength
- Simple - 2.5-4.5 J;
- Medium - 4.6-7.9 J;
- Heavy - more than 8 J.
The high impact force allows for breaking holes of huge diameters. But this is not surprising, because simple rotary hammers can do this.
Modes:
- No knocks - you need to purchase a special cartridge;
- Hammer drilling - drills holes;
- Chiseling - responsible for dismantling and drilling holes.
Cartridge type:
- SDS-Plus - popular, made for conventional and medium drills (5-30 mm);
- SDS-Max - for heavy devices (diameter 10-50 mm);
- SDS-Quick - Developed by Bosch, sold as one-off tools.
Cartridges
SDS + is used in household and compact products. The shank of such a tool has a diameter of 10 mm. A device with such a system can make a hole of 30 mm. This tool is the most popular because it is cheaper than other hammer drills with other types of fasteners.
The SDS-max concept includes professional devices. They make a vent up to 50 mm. Therefore, before work, it is worthwhile to securely fasten the drill. The shank has a diameter of 20 mm. Rotary hammers that weigh more than 8 kg are likely to have this mounting system.
SDS-Quick is used for instruments that operate on battery power. They are used to drill concrete, brick, thin metal and multilayer material. The shank design has a secure grip on the chuck and a long drill life. High quality brazing ensures high performance during hammer drilling.
There are also models of the SDS-Top system, which was made on the basis of SDS-Plus. But it differs with a shank with a 14 mm diameter. Perforators with this system are used to make small holes - 15-25 mm. These types have high reliability and durability.
The drill is fixed with oval grooves. Each system has two of them, but at the same time they differ in diameter: plus - 10 mm, top - 14 mm, max - 20 mm.
The torque is transmitted through long splines. Plus they are symmetrical, top - asymmetrical, max - three asymmetrical splines.
Which type is best for you?
Experts say that purchasing a professional hammer drill for household needs entails unnecessary expenses and a desire to show off. It is no different from the ordinary one. But if you work from 4 to 5 hours a day, then a household tool can only last a few years.
Additional functions
There are also a few things to consider:
Reverse switch:
- Lamellar: convenient to use, but does not tolerate dust;
- Push-button: manual, hard to tolerate dust;
- Brushed: user-tested. Does not lose the number of revolutions when rotating counterclockwise.
Convenience and safety:
- Anti-vibration system - does not allow hands to get tired during long work;
- Safety clutch - in case of a breakdown of the drill, the device is immediately switched off
No need to pay attention to the layout. It does not affect his capabilities in any way.
According to the shape and position of the engine
When buying this tool, you need to pay attention to the shape and design. If the device fits well in the hands, then the work will be convenient too.
There are two types of rock drills. The letter "L" differs from others in its compactness, since the engine is vertically located. These tools will not overheat because the motor is well cooled. Products of this type are durable and will last for a long time. But they weigh a lot.
Perforators of the straight type can be both narrow and long tools. They are significantly lighter than average devices. The design also allows holes to be drilled even in the most difficult to access areas. The motor is placed vertically.
Operating modes
Regarding the operating modes, they are divided into several groups:
- Single-mode fixtures. The simplest devices are suitable for working with wood and metal. The principle of operation is the same as that of the drill.
- For dual-mode, not only the rotation of the axis is important, but also its oscillation;
- A device with a three-mode function makes impacts without a spindle. It is a multifunctional tool. He is able to hammer and drill. But at a price it is more expensive than the above types.
For those who need to choose devices for drilling, chiselling or breaking, it is better to choose a three-mode device.
Power type
The device by the method of obtaining energy can:
- Powered by the network;
- Run on battery power.
The first ones require a wire - the average mains voltage should be 220 V. They are often used at home.
Rechargeable models can hold a charge for several hours.They are used at home and also among professionals when it is necessary to carry out construction or work in uncomfortable conditions where there is no electricity.
Equipment
Buying accessories in a complete set, you do not need to buy the necessary parts. In addition to the perforator, the case should contain:
- Adapter. This is a chuck that helps equip the hammer drill with conventional drills. If there is no adapter cartridge, then you will have to pay twice more.
- Additional brushes for the electric motor.
- A set of Boers. For normal use at home, it will be enough to purchase a basic kit. Professionals are expensive.
When it comes to choosing a manufacturer, BOSCH and MAKITA are considered the best. Those wishing to buy a professional device should pay attention to these companies.
Consumables
When buying a puncher, you need to bribe consumables for it:
- Shoulder blades;
- Files;
- Crowns;
- SDS drills (not for drills).
Consumables of different brands or models are most likely not suitable for each other.
When choosing a puncher, you should always look not at the price or popularity, but at the purpose of use. A properly selected rotary hammer, taking into account the expected frequency and conditions of use, the materials being processed, will give a good result.
