Why do we need a drill for concrete - types and scope

Building

Anyone who has ever tried to make a hole in the concrete on his own, knows that it needs to be drilled, not drilled. You can, of course, try to use a hammer drill with a drill in concrete, but this is only for very shallow and small hole diameters. In our article we will talk about various nozzles (a drill for concrete 20 mm, 30 mm, 50 mm and others), and how to handle them.

A variety of attachments - the first thing that may scare an inexperienced builder

Choosing the right drill

The very first thing I would like to start with is that to work with concrete one should use a puncher with drills - nozzles of the desired diameter, if you want to achieve the desired result, of course.

But that's not all, you can take a punch of any power and still not reach the goal. Only a well-chosen drill will be the key to the best results and accurate execution of the tasks.

Difference of the drill from a drill

At first glance, an unknowing person can hardly distinguish a drill for concrete from a drill with a pointy tip used on the base of a impact drill.

No, the differences are quite substantial:

The drill bit of complex shape according to the SDS standard, whereas the drill has a smooth.
Furrows on the drill, twisted in the form of a spiral, sharp-cutting, and in the drill, these same parts are designed to remove dust and crumbs of concrete formed during the drilling process.

Unlike their counterparts, nozzles on the perforator do not sharpen, cool or temper. They are usually disposable, are not subject to correction and repair. In this regard, they are usually sold in a package of ten pieces.

Attention! The operation manual of three-mode perforators allows to use them in a set with a drill in a drill mode, using a special adapter (included in the set). Borax can also be installed on a drill, but do not expect effective work from this union. Moreover, the nozzle can jam in the chuck, and instead of drilling you will repair the drill.

Here is a drill bit for a drill that can be used for shallow holes.

Kinds of nozzles on the puncher

It is definitely possible to decide which concrete boers for concrete are best suited for a particular case.

Replaceable nozzles on the perforator for drilling concrete and reinforced concrete have several modifications:

For drilling holes of small and medium size, resembling a drill in appearance. For example, the drill rod for holes with a diameter of up to 10 mm is made in the form of a screw with a tip and a cutting edge made of a carbide metal. The reliability of the tool, which is experiencing large shock loads, increases due to some rounding of the shape of the tip of the drill.

This builder has a set of different attachments.

Special nozzles crowns for the device of openings of big diameter at installation:

Switches.
Outlets.
Branching boxes.

When working, the destroyed base material remains inside the crown for drilling concrete.

Such nozzles for drilling tools are in turn subdivided into:

Diamond (with the corresponding name sprayed on the cutting edge) are used for hammerless drilling with simultaneous cooling with water.
Gear crowns for the so-called "dry" drilling, in which the edge is equipped with carbide teeth. These nozzles are designed to work perforator in shock mode.

Crown for drilling holes for communication

Industrial drilling

Drilling in the factory or at large construction sites, provided that it is necessary to perform multiple drilling with accurate marking according to GOST, is performed automatically with special equipment.

The drill machine for concrete, depending on the setting, is capable of drilling concrete in different directions:

Horizontal.
Upright.

Machine drilling is performed with diamond-coated nozzles and a jagged edge of different caliber:

For deep or through holes of small diameter.
Nozzles that cope simultaneously with the deep drilling of large holes (50x1000 mm and more).

Drilling and drilling machines with nozzles of different types are simply irreplaceable:

When performing the replacement of utilities in old buildings in the places of their passage through structures in places not provided for earlier (walls and ceilings).
When performing inputs of engineering networks into buildings through the foundation.
The device of inputs and passages of underground routes through reinforced concrete and concrete wells.

Note! Punchers perfectly cope with other types of work. Using a special nozzle, you can quickly and effortlessly dismantle an old tiling cladding or excessive concrete flows.

It is much more comfortable to hold the punch with a special additional handle.

The nuances of the process of drilling reinforced concrete

And still allow ourselves to give some practical advice for beginners and not only:

Always in the process of drilling, use the speed mode recommended by the manufacturer.
The period of continuous operation of the tool should not be long. In order to avoid overheating, the drill for reinforced concrete must be removed from the hole every 10 seconds and allowed to cool.
To combat the rapid heating of the nozzle you need to reduce its friction on concrete. To do this, before starting work, installing a drill for reinforced concrete on a perforator, put a little technical oil on the shank.
Try to constantly maintain the axis of drilling. Even with a slight bias, the drill (especially long) can break.
Do not use commercially available adapters that ostensibly allow you to use attachments for powerful tools on analogs in the class below. Producers, thus, try to unify their products, not one professional will not go for it.
If you have to do your own hands with a concrete structure that has a frequent reinforcement cage, immediately prepare diamond drills for concrete. They are just adapted to work in such conditions.

When working with a thin drill, be careful, any curvature can lead to deformation of the nozzle

Note! Instructions for each individual instrument gives clear recommendations for its operation. Careful examination of it will be the guarantor of a long service punch and always consistently accurate execution of the holes of the specified parameters.

In the end, it remains to add-acquire priority tools and attachments to them manufacturers with only good reputation, which have proven themselves in the international market. The price of such equipment is somewhat higher, but it will pay off with a long service life and quality of work.

Conclusion

We hope that the above information was useful to you, if only because you could learn more about the various options for punching nozzles (for example, that there is a drill for concrete 8x600 mm).

Remember that no matter what work you do, you should not neglect the safety of your family and friends. In the presented videos in this article you will find additional information on this topic.
