Even in the process of small construction or repair, it is often required to perform different work with a hammer drill. Thanks to him, it is possible to drill holes in reinforced concrete or natural stone, as well as make holes in them. Therefore, the peculiarity of working with this power tool needs to know in detail.
This professional tool allows you to quickly make holes in walls, blocks, wood and metal, as well as ditch grooves in the wall and floor. Also, with the help of special nozzles, you can hammer the anchor and tighten the screws.
Due to its wide functionality, the puncher is in demand in many construction and restoration works today. But you need to know how to work with a puncher. In this article we will tell you how to work correctly and, most importantly, safely with this tool.
Screwdriving
First, consider the work that can be done with this tool. Professional builders try to use all the features of a power tool to make the process more productive. This applies to the punch, so they are often screwed with screws and screws, in particular, for fastening critical structures.
Mortar Mixing
The puncher allows to mix high-quality solutions of small viscosity. For mixtures of high viscosity it is better to use a special nozzle. It is better to interfere at low speeds. The advantage of a power tool in this case is that the speed of rotation of the mixer can be increased or decreased at any time. This feature allows the punch to function as a construction mixer.
Wood drilling
If you do not know how to work with a wood puncher, then you just need to install wood drills in the power tool and turn on the drill mode. Depending on the thickness and density of the wood, a rotation speed is selected.
Tile drilling
A feature of working with ceramics is that this material is very fragile. Therefore, for such delicate work, you must turn off the shock mode. You need to start drilling with small revolutions. Then you should gradually increase the speed.
Metal drilling
Using a punch and a drill for metal, you can make holes in metals. In this case, helical drills with a cylindrical shank are used. These tools are made of high-strength alloys (most often based on cobalt).
How to work with a concrete puncher ?
With the help of this professional power tool and concrete drill with a special crown, you can make holes in concrete and reinforced concrete. But you need to make sure that the drill does not fall on the reinforcement, because it can deteriorate or it can bite.
Preparing the drill for work
It is necessary to prepare the tool before work if in the process of work it is planned to change drills, holes or nozzles. To do this, perform the following steps:
- remove and clean the cartridge;
- lubricate it from the inside;
- install a cartridge with a shifted lubricating ring;
- crank for a secure fit;
- lubricate the landing part of the drill or hole;
- insert a drill or hole into the chuck (check for fixation).
You also need to check the integrity of the power cable. Everything is done according to the safety operating instructions, which indicate how to operate the hammer drill in the desired mode. Before use, the power tool must be started in idle mode. This allows you to check the health of the device. Next, we will consider the use of a punch in different modes.
How to work with a rotary hammer in drilling mode?
It is recommended to start the drilling process at low speeds without a strong pressure on the power tool. After turning on the electric motor, you need to let it work in idle mode. This will allow you to immediately identify a malfunction before starting work if vibrations, any extraneous noise and smoke occur, which will protect you from injuries and the tool from breakage.
Work execution technologies directly depend on the type of material. Often there are difficulties with drilling metal. To do this, use drills designed for this work. In addition, you must first prepare the surface of the material. It is important to remove foreign objects and debris from it.
Drilling
How to work a puncher in drilling mode? In the process, you need to ensure that the hole does not warp and does not bite. Also, you do not need to press hard on the punch. It must be understood that this will not increase the power of the electric motor and will not accelerate the execution of work. So that the punch does not crank, you need to rest it in the body so that it does not crank after biting the drill. If the hole is stuck in the hole, then you need to turn on the reverse mode and unscrew the drill back. Of course, this mode is not provided in all drills. Therefore, you have to unscrew it manually by rotating the tool counterclockwise.
If the hole is clogged with dust and crumbs, you need to drive the drill into the hole several times (you can use a construction vacuum cleaner). In no case do not try to remove the crumbs with your hands, because mittens can be wound on a drill and you will get a serious injury.
Slotting mode
How to work with a puncher in the chiselling mode? Everything is simple here. To enable this mode, you need to turn the switch to the position with the image of the hammer.
For the jackhammer mode, you need to use nozzles in the form of peaks or blades. During operation, hold the tool with both hands because it vibrates a lot. The chiselling speed can be reduced or increased depending on the type of work performed. At the same time, constantly monitor the process with glasses, since during the chiselling of concrete or soil, small pieces of fragments fly off. If they get on the surface of the eye, this can lead to irreversible consequences.
Rotary Hammer Recommendations
There are several basic rules for working with a rotary hammer, which must be observed. There are only a few:
- In the process, do not press hard on the tool so that the drill does not overheat and be damaged. The speed of work from this will not increase, but the drill will be damaged, and you will have to buy a new one.
- Often they want to drill a deep hole in one go, but the drill is periodically clogged and needs to be cleaned. Therefore, the borehole should be pulled out of the hole periodically to clean the hole and the drill itself.
- Watch the operating time of the power tool, do not allow its damage and an overheat. When choosing a tool, pay attention to models with an aluminum case. Why should you choose them? It's simple: they cool better.
- It is desirable to work with a hammer drill in rubber gloves with anti-vibration inserts that are able to dampen vibration, even though special inserts are provided on the tool. Buy high-quality boreholes, because cheap boreholes break quickly, as a result, you will overpay more. Work with a hammer drill at height should be especially carefully, as as a result of jamming the drill may break off and the tool may fall down.
- Also, do not forget that the sounds of a working punch are very strong. Therefore, you need to work in the residential area at a strictly set time.
Is dust possible?
How to work a puncher without dust? The duration of its operation depends on professional care of the perforator. Particular care must be taken to lubricate the gearbox when working with concrete, because in this case the most dust is generated.
You can protect yourself from it with a vacuum cleaner. Some models have special fittings for attaching the hose. You also need to consider that in the process of working at low speeds, the tool quickly heats up, so watch for the duration of its work and rest.
After completing work and disconnecting the tool from the power supply, you need to clean it with a cloth from dust and dirt. The rag is allowed to moisten a little in a soap solution. Carefully monitor the condition of the ventilation openings. It is also important to periodically carry out tool maintenance.
Gear Lubrication
Before work, it is required to lubricate the drill shanks. This will avoid a heavy load on the tool barrel due to strong friction. If you do not stick to this, then very soon the tool will break, and you will have to repair it.
Conclusion
Follow all the recommendations, and the punch will serve you for many years, while working with it will be quite comfortable and safe. Just study the sections above how to work the puncher in various modes.
