⚙ Best Diamond Drills for 2020

Almost no construction activity is complete without a diamond drill. It is a professional tool that easily creates a hole of any diameter in mineral materials. The peculiarity of the product is that it is not required to carry out additional processing with auxiliary means before work, thereby reducing time costs. However, choosing a good model is not easy, you should know the main technical characteristics and capabilities of the device. The editors of the site "bestx.htgetrid.com/en/" have prepared for you a rating of the best drills for diamond drilling for 2020.

Scope of application

The device has a powerful electric motor, unlike standard versions. This solution makes it possible to create holes in solid material in a short space of time. At the same time, the user's efforts are spent many times more, this is also important to consider.

The product is often used when drilling load-bearing walls for the purpose of laying electrical wiring. But the product is also used for:

• Correct organization of water supply or heating system in apartment buildings;
• Arrangements of ventilation systems;
• Niche creation;
• Installation of air conditioners;
• Conducting a gas pipeline or sewer system.

The drill for diamond drilling has good accuracy, which is why it is used when creating doorways of a standard shape. For almost all technical characteristics, this option is the most preferable for use in professional construction. The device is many times better than standard analogs and perforators.

To work with this equipment, diamond bits are used. Most of the work is done without the use of racks. The user holds the device in his hands and performs drilling. If you need to make a hole with a diameter of more than 100 mm, it is best to fix the drill to a construction stand.

Main technical parameters

Regardless of the manufacturer and the drilling method, each drilling device has the following parameters:

• Power. The optimal power value is 1500 W. The performance of the tool depends on this indicator. It should also be borne in mind that the manufacturer often indicates the maximum figure. However, professionals recommend not to operate the product at high speeds, as the device may fail. If a person is not limited in a budget, it is better to look for products with a power rating of 2000-3000 W so that you can use the device without any problems.
• Weight. This parameter only affects the usability. The lower the weight, the more time a person can hold the device in their hands, respectively, this makes it possible to perform more work. If possible, it is better to buy a balanced version or a light one. Heavy products will not reach their full potential.
• Drilling diameter. The parameter indicates the maximum and minimum values ​​of the holes to be created. This is important to consider as it affects the correct selection of the diamond core bit.Often the maximum diameter is 750 mm, while the minimum is only 6 mm.
• Features of the cartridge. There are no difficulties here, since there are only two varieties, the first is tightened with a specialized wrench, and the second does not require accessories for clamping the drill. The latter option is in high demand as it allows replacement at high speed.
• Additional features. Each product has ancillary functions, such as a two-speed mode of operation, which allows for fast hole creation of any diameter. In addition to it, drills are produced with short circuit protection, heating control, speed limitation, anti-vibration system, etc. The number of functions affects the final cost of the product. If a person does not need some options, then it is better to refuse them so as not to overpay.

Drilling varieties

Often when carrying out repair work in residential premises, the technology of "wet drilling" is used. This requires a continuous supply of fluid. To do this, a special tank is used, which is connected to the device; it is not necessary to look for deep containers, since only 10 liters are required for work. This solution is necessary, since water cools the tool, which eliminates the chance of overheating. In addition, with wet drilling, dirt becomes less, which makes it possible not to carry out redecoration after creating the holes. But there are more wet areas, which is a disadvantage.

For dry drilling, you need to buy dust extractors, which are installed in the working part. It is also necessary that the drill is equipped with a heating control system so that the device does not break at the wrong time. Dry drilling is often necessary to create holes in masonry.

For convenience, it is allowed to use a product with the ability to reverse and adjust the speed modes. The auxiliary functions will allow you to carry out work many times faster and better.

The choice of diameter is not so important, but it is better that the product works with different drills, this increases the versatility. Therefore, it will become easier for the builder to drill walls, including load-bearing ones.

We must not forget about goals. If a person purchases a tool for home use, then it is better to use cheap devices, the main thing is to buy from well-known manufacturers. For the professional sphere, devices of a high price segment are suitable and several additional functions that will make the work easier. In addition, the drill must withstand high loads and be equipped with overheating control.

Professionals recommend buying a product that has good ergonomics.With such a device, it will become much easier to perform even complex work, so you do not need to ignore this criterion.

Can be attached to building posts. To create even and beautiful holes, it is necessary to fix the tool on a special stand. Most products support this feature, but there are exceptions. It is important to clarify this parameter in advance so that in the future there will be no problems using the device.

However, if a user buys a product from an unknown company, it is necessary to read reviews on the Internet to learn more about the advantages and disadvantages of the device.
