Perforators with a vacuum cleaner: types, selection and manufacture

Modern construction tools have a ton of additional features. They allow them to stand out from their peers and attract buyers. In addition to the fact that modern rock drills combine the functions of both a jackhammer and a drill, they also allow you to quickly change the chuck attachments, select the operating mode, and control the quantitative indicators of rotations and impacts.

In addition to those listed, among the additional functions you can often find the presence of a built-in vacuum cleaner. This characteristic should be given more careful attention.

Many will not even think about what the function of a vacuum cleaner in a perforator is for.

It's no secret that dust appears during the operation of the hammer drill. Its quantity and composition depends on the material with which the work is carried out. Someone will consider the presence of dust not so much of an inconvenience, but it should not be underestimated either.

• In the dust there are also very small particles that settle on the skin and clothing of a person. If they are constantly inhaled, respiratory diseases, as well as allergic reactions, may appear. In addition to a vacuum cleaner, it is imperative to use a respirator and protective clothing.
• This affects the convenience of the person. Working in dust is not very pleasant, but it is simply impossible to hold a regular vacuum cleaner and work with a puncher at the same time. For people whose daily work is associated with this tool, the presence of a dust collector in it will greatly facilitate the work.
• Small dust particles have a negative effect on the operation of the construction tools themselves. For example, the boot on the cartridge may fail.
• After any work performed with a conventional hammer drill, a thorough cleaning is required.

All rock drills with different types of dust collection systems can be roughly divided into professional and amateur (for home use). Due to their high power and weight, professional ones are designed for certain types of work. Tools for regular use often combine several modes, they are less powerful, and they are lightweight. Naturally, the cost of the former is several times higher.

Only a person who uses a puncher regularly, on a professional basis, can afford to buy them. With the help of the latter, it is quite possible to make simple repairs with your own hands or periodically make several holes for household needs. Devices for collecting dust and small debris can be of different designs.

• Special dust extraction systemto which a construction vacuum cleaner can be connected. Their main advantage is their high power and the ability to absorb large amounts of debris. Portable construction vacuum cleaners do not greatly affect mobility and convenience. Larger industrial vacuum cleaner models often have power tool sockets, which is also convenient. In this case, each device works autonomously.
• Built-in vacuum cleaner, whose work is directly related to the hammer drill motor.It can be completely removable or only part of the container (bag) for collecting waste. Such a dust collector partially hides the power of the rock drill and affects its durability. This system is suitable for instruments with light to medium characteristics.
• Dust collectors... The essence of the action of which is that they do not allow small particles to scatter in different directions and retain them inside the chamber. Usually these are plastic nozzles in the form of a cone (also called dust caps) or a cylinder. They come in a solid or ribbed cuff that can compress slightly and provide a snug fit. Some of them still have an entrance to which you can connect the hose of a regular household or construction vacuum cleaner. The choice of such dust collectors depends on the type of cartridge, the model of the tool and the maximum possible parameters of the hole (depth and diameter).

To make the advantages and disadvantages of perforators with vacuum cleaners more clear, consider several popular models.

• Bosch GBH 2-23 REA proved itself exclusively from the good side. The design of the vacuum cleaner is easily removable. Inside you can see a filter and a container for collecting small construction waste, which is quite easy to clean. Without a filter, the tool works like a conventional hammer drill with two modes. It copes well with the declared functions, retains more than 90% of dust and is convenient for transportation.

• MAKITA HR2432 captivates with reliability and good performance. The dust collector can be detached - then you just get a good rotary hammer. The bag is very spacious, even with intensive work it can be emptied every two days. Unlike other analogs, the garbage does not spill out when the unit is turned over. Convenience is especially noted when working with the ceiling - dust does not fly into the eyes and cleaning is practically unnecessary.

The storage container is large enough to store the hammer drill when assembled.

These two models with dust extraction are not the only ones, there are not so many of them on the market, but there is a choice.

Still, the choice of tool depends on the planned work.... To hang several paintings, you can take the first model. For larger actions, the second is better.

The choice of a dust collector largely depends on its cost. It is not always possible to make an expensive purchase. And when buying, it is difficult to take into account all the nuances.

The easiest option with the horizontal position of the punch is to make a pocket in the place of the future hole. Plain paper and masking tape work well for it.

When the rock drill is in a vertical position, with debris flying from above, this method is not suitable. Here you can use any plastic dish, be it a glass or a cut bottle. In the bottom, you need to make a hole equal to the diameter of the drill. During work, if the length of the drill is insufficient, the cup is wrinkled, but retains the bulk of the debris inside.

The main thing is to calculate the diameter you need. This method is more reliable and will collect dust better than the previous ones.
