Rating of the best diamond drills for 2022

The drill belongs to the category of tools that every self-respecting owner of a country house or plot must have. It is used for drilling holes in surfaces of different density (metal, brick, concrete, wood). For housework, it is enough to purchase the simplest drill. When repairing, you may need a more functional model from the best manufacturers. In this case, you simply cannot do without a diamond drilling drill. The quality index is affected by the strength of inserts and diamond crowns.

Application area

The main area of ​​​​use is heavy work, which involves making holes in hard materials. There is no better tool to perform such functions. With the help of such a unit, according to buyers, you can easily make even and smooth holes in the material of any strength level. Found their application for electrical, ventilation and plumbing work. It should be noted the noiselessness of the operation of a drill for diamond drilling, compared with a jackhammer. Also in the process there is no dust, excessive vibration and shock.

It is used in cases where the processing of fragile materials is carried out, the risk of destruction of which is high. The margin of safety of such devices is colossal, which is extremely important when working with walls with transitions.

Despite the undeniable advantages, such a unit belongs to the category of professional tools that can be bought at any online store. For personal use, equipment is rarely purchased, unlike conventional drills, due to its impressive dimensions and high cost. However, during construction, the device is indispensable, so it is often offered for rent by large enterprises and manufacturers. In addition to the huge power, it can be used for a long time, eliminating the need to take breaks.

To make large holes, it is recommended to use professional models that can be fixed on special racks or stands. An example is the DeWalt D-215-85, which can make holes in concrete up to 25 cm in diameter.

For any type of drilling, including dry diamond, special diamond crowns are used, which allow making through or blind holes of any diameter. In addition to dry, operation is allowed with the supply of liquid, which is used for cooling. In this case, the device will be equipped with a system for supplying fluid to the area where the crown is located. To remove residual moisture, a construction (industrial) vacuum cleaner is used. Wet type of work implies the absence of dust in the room. The most powerful power tools are considered to be devices that are equipped with diamond crowns.

In addition to a significant margin of safety, the best designs have a considerable depreciation resource.

What to look for when choosing

Buyers make the main mistakes when choosing because before going to a hardware store they do not get acquainted in advance with the types and types of equipment they are interested in. Attention should also be paid to the advantages and disadvantages of popular models. Hammers and drills of this type are considered the best units for making holes in materials of any level of strength.

What are the work surfaces?

1. A natural stone.
2. Solid brick.
3. Reinforced concrete structures.

By structure, diamond drills are similar to conventional drills, however, the main distinguishing feature is the presence of a diamond nozzle. Also, the devices differ in the principle of drilling. The drill, which is widely used in construction, has the shape of a cup.Due to the design features and high reliability of the assembly, the unit practically does not emit extraneous noise during operation. Also, the best manufacturing companies managed to reduce the friction index. A person will not need special protection for the respiratory tract, since there will be practically no dust (or not at all).

The increase in productivity is observed in the process of decreasing effort. Thus, the recesses will have the correct round shape. There will be no chips or breaks at the corners.

The main disadvantages of the equipment	Description
Water	During operation, the floor will always be splashed with drops of water, as it is necessary for drilling.
Price	The cost of a professional unit is high, but as additional costs it is worth mentioning consumables and accessories that will also be needed.

Additional accessories

The crown is necessary for the normal operation of the equipment. It is a metal cylinder, the lower part of which is completely open. On its edge are located cutting elements with soldering (diamond). Crowns come in diameters of 20-350 mm. On the reverse side is a small tail, which is required for connection with a spindle or chuck. The established security measures require fixing the appliance on a stand or rack if the crown diameter is more than 6 cm. Otherwise, the consequences can be tragic if the crown slightly jams.

The complete set of expensive structures includes not only drills, but also auxiliary anchors, smooth feed mechanisms, and stands. However, there are tangible advantages to this method of attachment. So, the method guarantees the creation of holes strictly perpendicular to the surface, without any flaws.In order to get the most out of the purchased device, it is necessary to understand the principle of the functioning of the crown.

The cutting elements are made from a mixture of diamond grit and a number of bonding elements. In the process of use, the ligaments will be erased. The particles of diamonds that protrude beyond the edge crumble and crumble. If the crown, or rather its working surface, is harder than the material being processed, then the drilling time increases. If the indicator is reversed (softer), then the crown will quickly fail. To date, the world's best manufacturers are trying to find the optimal combination between the composition of the binding element and the shape of the crown.

What to look for when choosing

When buying a tool of this type, the first thing you should pay attention to is the equipment and, in particular, the availability of additional equipment. In most cases, drills are classified as universal, so they can be used in combination with equipment from different manufacturers.However, it will not be superfluous to have several adapters. Most drills that are designed for home use are equipped with 8 cm drills. Otherwise, you will need to purchase an additional hole saw.

The same situation applies to rotary hammers, the accessories for which may be incompatible if the sets were purchased from different manufacturers.

Often, brands carry out inspection and measurements of drills on their own products, without focusing on the products of other companies. Most experts recommend buying equipment and accessories for it from one manufacturer. Otherwise, the service life of the latter can be significantly reduced, as well as the quality of the work done. Such expenses are justified only if a person plans to devote himself to construction. In order to make a small hole in concrete or brick, such expenses are not advisable.

Conclusion

In order to minimize possible costs, before buying a diamond drill, you need to decide on the type and amount of work to be done. If we are talking about a one-time use, then it is much more profitable to rent the device for several days. The main difference about the best models lies in the types of working surfaces, the diameter of the holes being made and the engine power. An important aspect is the presence of a cooling system in case the continuous use of the purchased tool is planned.

For everyday tasks, you can purchase a cheap model that will pay off in the near future. If a person has decided to devote himself to construction or start working in this area, then you simply cannot do without a quality unit.
