What is a hammer drill
Before installing a drill in a perforator, first of all, it’s worth understanding. Today it is difficult to finish repairs or construction without resorting to using a perforator. When drilling is needed, this tool is simply indispensable. The punch is used during work with concrete and brick, it is also often used for work on metal or wood as a regular drill.
Many functions make this tool universal. rotation with impact, impact without rotation, rotation without impact, drilling in concrete, function of a jackhammer, drilling in wood and metal and many others. You need to know that there are many types of hammer drill. The principle of using the tool is the same, but if you need to drill a wide and deep hole, it is better to use a larger and more powerful device.
To work with this tool, you need various snap-ins. drills, concrete drills for perforator, chisels, blades and crowns. Drills and crowns are used when drilling holes, drills are designed for concrete and stone, bits are used for mortising work, and blades are needed to knock down plaster or old tile. All the nozzles on the punch have the shape of a shank, due to which fast and reliable fixation in the cartridge is carried out.
Special angle nozzles, a dust extraction system, mixers for mixing mortars or paints, chisels and various types of nozzles (sharpening drills, a water pump, a nozzle for cutting metal in sheets) can also be used with a hammer drill. Before starting any work with a rotary hammer, make sure that it is properly equipped and suitable for future work. A tool too small may not be able to handle the heavy load.
When working with a hammer drill, be sure to remember the protective equipment. These include glasses, earplugs, and gloves. You should also work in special clothing, excluding anything that might accidentally wrap around a drill or drill. When working with the device, do not put pressure on it; this may end badly.
Try not to idle the tool for too long, this is only allowed before checking it. When working with porous material, use hammerless drilling so that it does not crumble. If you have to work with solid material, it is better to use a cutting fluid emulsion. If the work involves the use of a long drill, to save money, you can start working with a shorter metal drill for a perforator, but of the same diameter.
Grease the drill shanks every 180-200 holes. Pay attention to the heating of the instrument, with strong heating it is better to take a break. Alternate periods of work and rest of the tool. As a rule, a break is done every thirty minutes. Its duration. about ten minutes.
How to insert a drill into a hammer drill: step by step instructions
If, when working with a puncher, all the rules are taken into account and attention is paid to the subtleties, the work will be done competently and easily. Always follow construction technologies and do not forget to periodically check the tool for malfunctions.
Before you start replacing the drill or working with the tool, you must make sure that it is working. To do this, insert the plug into the outlet, and put the hammer into the drilling mode without a fight (left extreme position). After that, the start button is pressed. If you hear an even sound, devoid of glitches and jerks, you can get to work.
Before starting work, do not forget to check the walls or other surfaces for water or electrical wiring. The handle must be securely fastened and not loose during operation. A timely check or inspection will help to avoid injuries and breakdowns of the device.
Please note: never touch the rotating parts of the tool, otherwise it can lead to a sad outcome. For the same reason, it is only necessary to install the drill chuck and drill for the bosh punch with the plug unplugged from the socket.
You need to purchase a special chuck that fits your rotary hammer model. If you can’t choose or don’t know which cartridge is needed, it’s best to take a tool with you and try compatibility on the spot.

Today, rotary hammers are equipped with two types of cartridges. keyless and key. The key option is traditional, the drill on a tree for a puncher in it is clamped using a special key. In this case, the mount is reliable, but less convenient than that of the quick-release chuck. The keyless chuck easily clamps the drill without the aid of any tools. Just choose the most suitable option and follow the further instructions.
Choosing a drill for a hammer drill
Today, drills are made from carbon, high speed and alloy steels. If you have to work with durable materials, the drill can be equipped with heavy-duty hard soldering. Drills are feather, centering, with straight flutes and spiral (for deep drilling).
You can also purchase a drill designed for wood, metal, stone, concrete, glass, ceramic, diamond or a universal option. Before you fix the drill in the punch, you need to decide on the type, if you want the work to be done correctly. The color of the drill indicates the form of the final result.
If the drill is painted black, it means that it was treated with superheated steam, but this does not affect the quality, despite the popular opinion that black drills are stronger. If the drill has a brown or slightly golden hue, most likely it was subjected to tempering to relieve internal stresses. Drills that are processed with titanium nitrile have a bright golden color, such options are the most expensive and durable.
As a rule, good companies indicate on the drill box its characteristics, such as the grade of steel and the material with which it is possible to work. If the drill heats up significantly during operation, it means that it has become dull or has been sharpened incorrectly.
How to get a drill from a punch
If an old drill bit is inserted in the punch, it must be carefully replaced. Before pulling out any nozzle, be sure to pay attention to the type of its cartridge. Remember, the keyless and keyless chuck. The key is more reliable, especially when working in shock mode. This cartridge is made of metal, therefore it is less exposed to mechanical damage.
Before you pull out the drill from the punch with a double-coupled quick-clamping chuck, it is imperative to switch the device to reverse mode. After that, it is necessary to fix the lower sleeve with one hand and with the other. unscrew the top. In a one-jaw cartridge, the nozzle can be replaced with only one hand, since it is placed on rotary hammers with automatic locking of the shaft.
If the drill is stuck
There are times when the working tool is stuck in the cartridge and does not want to be pulled out. Here you need to know the following. To gently pull out the nozzle, it is necessary to clamp its free part in a vice and hammer the cams of the chuck through a wooden extension with a hammer until the drill tail comes out of the quick-clamp chuck. If the drill bit is stuck firmly in the punch, and this does not help, you can remove the cartridge and place it in gasoline, and drop a little automobile oil into the key cartridge.
Also, there are often situations when the drill gets stuck in the wall during concrete construction work. This occurs during clamping between concrete and reinforcement. You must stop pulling the trigger and loosening the hammer, as it may break. To get started, pull the drill out of the chuck, replace it, and begin to carefully knock out the concrete around the stuck drill. Avoid getting stuck in a drill. After this procedure, a stuck drill can be removed without difficulty.
For proper operation of the tool, it is necessary to lubricate the punch with special grease. It is better to purchase a proprietary product that is resistant to water and prevents moisture from entering metal surfaces, which prevents corrosion from appearing.
To do this, open the tube with grease and squeeze a little into the hole into which the nozzles are inserted. Next, the tool is placed on the floor or on another hard, solid surface with the handle, after which the back of the punch head is pulled down, the chuck is inserted, and the lower part of the head returns to its previous position.
After the above steps, you can insert the Makita drill bit into the chuck. Then, by rotating the upper part of the cartridge clockwise, it is necessary to clamp the drill. After this, be sure to check whether it is firmly fixed.
If you understand that the drill is loose, try tightening the chuck harder. After the final fastening and compliance with all actions, you can turn on the hammer in the network. Press the start button several times so that the grease can disperse well into parts.
Beginning of work
Before starting work, you need to make sure what mode the tool is in. For one minute, he should be idling. Be sure to check the operation of the gearbox so that it does not emit vibrations, excess noise or sounds. Nor should smoke or odor resemble burning insulation.
For drilling, it is necessary to install the drill in the place where the hole will be made and only then press the power button. When working with a punch, do not put too much pressure on the surface. Modern rotary hammers have the property of on / off. This property of the tool is able to provide the main work with a decrease in speed. Thanks to this mode, the hole will be made in a precisely defined place and the drill will not go to the side.
When drilling metal or wood, do not turn on the shock mechanism, this can lead to damage to the device. There are rotary hammers in which an automatic shutdown mechanism is installed when the wrong option is selected. During construction work, drilling can be used for drilling concrete. To free a hole from dust, it is necessary to periodically remove a part of the drill and return it to its place.
Rotary Hammer Operation
How long the hammer will serve will depend on compliance with all the rules of its operation. When working with a material such as concrete, you should not save money on lubricating the tool. If the tool fails, it must be taken to a service center. Even if it is not damaged, from time to time it is worth taking it for inspection by masters.
Please note that some malfunctions provoke injuries, this is especially true for powerful punchers with a strong blow. If the drill in the punch is jammed strongly, or you are not completely sure of your abilities, it is also better to seek the help of qualified specialists!
To clean the tool from building dust, you can use a vacuum cleaner. When using a punch, it is worth remembering the rest mode, the device tends to heat up even at low speeds. Follow the instructions that came with the device.
Given all the above, it can be concluded that the self-insertion of the drill into the hammer is a very simple procedure. Also remember that under the law, a hammer can only be used after seven in the morning and until eleven in the evening. Try to carry out repair processes on weekdays from nine in the morning and finish them until seven in the evening.
