The puncher has long ceased to be a tool that can be found exclusively in the workshop of a professional. Today, this equipment is actively used in everyday life. With it, you can carry out repairs and speed up construction. And it can cost quite inexpensively, but just do not count in this case on high performance and the possibility of continuous long-term operation without overheating of internal components and the case.
Before choosing this device, it is necessary to consider several factors, among them the impact energy, which is one of the main characteristics. Joules are used to measure it.
By acquiring a lightweight model, you become the owner of a tool with an impact force of no more than 2 J. Whereas punchers can hit more seriously with a force of up to 15 J. With an increase in the impact energy, you can get holes of a larger diameter.
It is also important to consider the frequency of impacts. The larger it is, the higher the punching speed will be. The performance of the unit will depend on this characteristic, as well as the impact energy. Well-known manufacturers that produce effective and durable devices have learned to successfully combine these parameters. However, before purchasing a particular model, you need to consider several options. A great example is the Hilti rock drill, which will be discussed below.
Overview, specs and pricing for the TE 70-ATC / AVR
This combination hammer drill is quite expensive. Its price is 85,000 rubles. The design provides for the presence of a cartridge type SDS Max. The reduced impact energy is 5.5 J. The energy of a single impact is 11.5 J. The device has an optimized mechanical clutch that provides maximum torque transmission. The latter can be actively monitored thanks to a unique technology that instantly stops the engine when the drill is jammed.
For a long service life and increased strength, the body parts are made of fiberglass reinforced. The Hilti TE 70 rotary hammer can be used to drill holes for heavy loads. The diameter can vary from 20 to 40 mm.
Using equipment, it is possible to drill with high torque in wood and steel workpieces. Using drills, the diameter of which is equal to the limit from 12 to 150 mm, you can drill:
- concrete;
- a natural stone;
- masonry.
In first gear, the rotation speed without load is 360 rpm. The device weighs 9.5 kg. Its dimensions are 540x125x324 mm. Among the additional options, it is worth highlighting the chiselling function and the presence of a service indicator. The network cable has a rather impressive length, which is 4000 mm.
In addition, with this Hilti rotary hammer, the price of which for many consumers may seem quite impressive, you can use the TE DRS-Y dust removal module, which is not included in the package.
Overview, characteristics and cost of the TE 7-C puncher
This model of equipment is cheaper - 24 500 rubles. The tool comes in a suitcase, has an assembly cartridge in the kit, as well as carbide drills. Without a load at the first speed, the number of revolutions per minute will be 900. The unit weighs 3.5 kg.
The maximum drilling diameter is 28 mm. The rated power is 720 watts. An additional option is reverse. The noise level during operation of the equipment reaches 110 dB. Hilti TE 7 rotary hammer can work in one of three modes. Among them:
- chiselling;
- drilling without impact;
- impact drilling.
Overview, specs and pricing for the TE 7-C
An alternative solution to the above equipment is the Hilti TE 7 C. puncher. Its cost is 15 900 rubles. The equipment combines thoughtful ergonomic design and high structural strength. The tool can be used for intensive and frequent work with impressive loads.
The unit can be operated for drilling and drilling holes in concrete and masonry. After working with the chisel, you can process the surface by wrapping a screw or creating a recess. An advantage is the D-shaped handle, which provides convenience and safety even during prolonged use.
Impact energy reaches 2.6 J. Equipment provides the ability to work in one of three modes:
- drilling;
- drilling;
- hammer drilling.
Hilti rotary hammer has a modern SDS-plus chuck, with which you can change the drill or drill, which helps to reduce vibration. For precise control of the drilling depth, the design provides for the presence of a depth gauge. The kit includes:
- depth gauge;
- hammer drill;
- removable adjustable side handle;
- case.
Mass and rotation speed
The device weighs 4.99 kg. The manufacturer gives a guarantee for manufacturing defects. She is not limited to time. The length of the network cable reaches 4 m. With the Hilti puncher in aluminum, you can make holes with diameters from 4 to 22 mm. In the case of wood, this parameter reaches 20 mm, while when working with steel - 13 mm. The power of the device is 720 watts.
At idle, the rotation speed reaches 740 rpm. The minimum diameter of drilling with a drill is equivalent to 8 mm, the maximum value reaches 16 mm. Using the crown, you can make a hole with a diameter of up to 68 mm.
Overview, specifications and cost of the battery model TE 6-A36-AVR
If you often work in areas where it is impossible to connect to the mains, then you should choose a Hilti cordless drill . An excellent example of such equipment is the TE 6-A36-AVR model, which can be purchased for 35,000 rubles. The kit comes with:
- suitcase;
- carbide drills;
- battery;
- Charger;
- cordless hammer drill.
Without a load at the first speed, rotation can reach 1040 rpm. The tool weighs 4 kg. It has the option of actively absorbing vibration. The capacity of the battery supplied with the equipment is 3 Ah. You can monitor the battery charge thanks to the indication.
Voltage and Dimensions
The nominal voltage is 36 V. The maximum drilling diameter is 20 mm, while the minimum value is equivalent to 5 mm. An additional option is a depth gauge. You can use the reverse switch.
The dimensions of the equipment are quite compact and equal to 344x94x215 mm. The design provides for a dust extraction system. You can work with the equipment in drilling without impact and drilling with impact modes. The noise level during operation of the equipment is 99 dB. Under load, the shock frequency is 5283 per minute.
Finally
Hilti rotary hammers are offered for sale in a wide range. They come in different capacities and impact frequencies. The first parameter is a pretty important feature. If the equipment is equipped with an SDS-Max cartridge, then its power can reach 1.2 kW.
