Hammer drill - a device that combines the rotary motion of a drill with a reciprocating motion. In the article we will talk about the best rotary hammers with dust collectors.
Content
This is a powerful device that combines the functions of a drill, jackhammer, screwdriver.
It can be used for various jobs:
Manufacturers have created a wide range of fixtures for drywall, dismantling and installation of facade structures, as well as for home use. That is why the device for expanding the door and demolishing the walls will be inconvenient for attaching metal profiles (too heavy), and the “home” device will not withstand intensive work at the construction site.
A few tips will help you cope with the task and find the perfect solution for your needs.
A classic hammer drill can perform functions such as drilling (mixing mortar, driving screws), impact drilling (breaking through a concrete surface) and chiselling (disassembly).
SDS+ class devices have all of these modes and are versatile. SDS-max rotary hammers do not drill without impact and are therefore only suitable for special construction tasks.
SDS+ ("light hammer drills" for 10 mm reverse drills) are limited to a maximum impact energy of 5.5 J and are used for drilling holes up to 30 mm in diameter (for concrete). To increase the figure to 68-80 mm, it is necessary to use crowns on the stone. The SDS-max clamping system (“heavy equipment” designed for drills with a back diameter of 18 mm) is professional and is used in rotary hammers with an impact force of up to 33 J. The maximum diameter without a crown is 53 mm, with a crown up to 160 mm. Another option is the SDS-Quick (quick clamping device) system, which some Bosch rotary hammers are equipped with. Due to the characteristics of the head, it is not suitable for efficient chiselling and drilling.
Most models on the market are connected to the network. Cordless rotary hammers are also available for working at high heights and in special conditions.Since impact drilling and chiselling require a lot of energy, such devices are not very convenient to use, and their cost is quite high.
Household perforators have an impact energy of up to 2 J: it is enough to drill a wall, remove old plaster, break a brick. The higher the impact energy, the easier it is to drill concrete, break brick, granite.
Most models on the market operate in the 600-800 watt range. This is sufficient for domestic needs, but not for professional use. The higher the power, the more durable the device, but also the higher the level of energy consumption. Therefore, to dismantle bricks, concrete walls, you will need a puncher with a power of 1000 W or more.
Working at height in the absence of electricity requires battery technology. It is much more expensive and heavier (an additional load is created from the power supply). However, a puncher is just the device that is best powered from the network. Such devices are stronger, more durable and cheaper.
The faster the drill rotates, the more it heats up properly, there is a risk of breaking or tearing the active tip. It takes much less effort to hammer a foam block than when working with a brick or concrete wall.
Adjusting the number of revolutions allows you to adapt the hammer to a particular need.
Thus, all of the above functions are related to each other, the drill clamping system affects the number of operating modes and impact energy.
SDS+ devices are designed for chiselling, impact and conventional drilling, so they can be used at home and for some professional purposes. However, the impact energy and the maximum hole diameter are limited, which limits the scope of the method.
Devices with SDS-max connectors are suitable for dismantling walls, making deep channels in concrete, removing porcelain stoneware and self-leveling floors. However, their heavy weight makes them unsuitable for applications such as suspended ceiling mounting rails. The absence of the “drilling” function prevents crimping and cutting holes in ceramic tiles.
Universal perforators are designed for impact and conventional drilling, chiselling. They have an SDS + fastening system and are suitable for domestic and professional needs (including the installation of plasterboard structures, concrete and stone work, facade repair). SDS-max rotary hammers are not suitable for home use. These are powerful tools needed for impact drilling and chiselling. For SDS +, drills with a shank diameter of 10 mm are used, for SDS-max - 18 mm (the second option is much more expensive and less common on sale).
If the device is used for dismantling, assembling frame houses, destroying floors and walls, then the impact energy is 2.5 J or more, the power required is more than 900 watts. The parameters also determine the durability of the device, which depends on the type of engine. The more complex the tasks, the higher the specific characteristics should be.
Devices with an extended rear handle reduce the impact of vibrational forces on the hands of a person, respectively, and the damage resulting from the use of technology is reduced.
For domestic needs, as well as electrical work, demolition of walls, superstructure of doors, the device can have any weight: its service life will be short. But if we are talking about such tasks as installing stretch ceilings, devices for built-in appliances, it is better to buy lighter devices. In this case, it is more comfortable to work.
These include:
Theoretically, you can do without them if the device is used for domestic purposes. But for professional use, the options can be very useful, making work more convenient and efficient.
To work with a hammer drill, you will need drills, chisels, crowns and much more. If the manufacturer supplies them complete with equipment, then this is a clear plus, although they will not be enough for a long time.
You should not buy a puncher without a suitcase: since the device is quite heavy, it is difficult to carry and inconvenient to store.
An interesting constructive variety is a perforator with a dust collector with high power, force and speed of impacts, a significant diameter of the holes, they have a relatively small weight, an anti-vibration system, as well as a conveniently located and comfortable dust extraction system. In addition, with an SDS Plus chuck connection, these models provide easy replacement if you need to change the working nozzle. In addition, there is a reverse function, which allows the use of a hammer drill instead of a screwdriver, eliminating the need for additional costs.
Some models are equipped with a dust extraction system. Such punchers are necessary for professional work in the conditions of functioning objects (shops, hospitals, administrative buildings).
