Rating of the best diamond drills for 2024

The drill belongs to the category of tools that must be in the possession of every self-respecting owner of a country house or plot. 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, a diamond drill is simply indispensable. The quality index is influenced by the strength of inserts and diamond core bits.

Application area

The main area of ​​use is heavy work that involves punching holes in hard materials. There is no better tool for performing such functions. With the help of such a unit, according to buyers, it is possible to easily make even and smooth holes in the material of any strength level. Found their application for electrical, ventilation and plumbing works. It should be noted the quiet operation of the drill for diamond drilling, compared to a jackhammer. Also, there is no dust, excessive vibration and shock during operation.

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

Despite its undeniable advantages, this unit belongs to the category of professional tools that can be bought in 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 irreplaceable, therefore it is often offered for rent by large enterprises and manufacturers. In addition to its enormous power, it can be used for a long time, eliminating the need to take breaks.

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

For any type of drilling, including dry diamond drilling, special diamond bits are used, which allow making through or blind holes of any diameter. In addition to dry, operation with a liquid supply, which is used for cooling, is allowed. In this case, the device will be equipped with a system for supplying fluid to the area where the crown is located. A construction (industrial) vacuum cleaner is used to remove residual moisture. Wet type of work implies no 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 structures have a considerable depreciation resource.

What to look for when choosing

The main mistakes when choosing, buyers make because before going to the 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. Rotary hammers and drills of this type are considered the best aggregates for making holes in materials of any strength level.

What are the working surfaces:

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

In structure, diamond drills are similar to conventional ones, however, the main distinguishing feature is the presence of a diamond bit. Also, the devices differ in the principle of drilling. The drill, which is massively 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 firms managed to reduce the friction rate. A person will not need special protection for the respiratory tract, since there will be practically no dust (or no dust at all).

The increase in productivity is observed in the process of decreasing efforts. Thus, the indentations will have the correct round shape. No chips or breaks will be found at the corners.

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

Additional accessories

The crown is necessary for the normal operation of the equipment. It is a metal cylinder, the bottom of which is completely open. On its edge are the cutting elements with soldered (diamond). Crowns are 20-350 mm in diameter. On the reverse side there is a small tail, which is required to connect with a spindle or chuck. The established safety measures require fixing the electrical device on a stand or stand if the crown diameter is more than 6 cm. Otherwise, the consequences can be tragic if the crown is slightly jammed.

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

The cutting elements are made from a mixture of diamond chips and a number of connecting elements. The ligaments will wear off during use. The diamond particles protruding beyond the edge crumble and crumble. If the crown, or rather its working surface, is harder than the material being processed, the drilling time increases. If the indicator is the opposite (softer), then the crown will quickly fail. Today, the world's best manufacturers are trying to find the optimal combination between the composition of the bonding 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 presence of additional equipment. In most cases, drills are classified as universal, so they can be used in conjunction with equipment from different manufacturers. However, the presence of several adapters will not be superfluous. Most drills that are intended for home use are equipped with 8 cm drills. Otherwise, you will need to purchase an additional crown.

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

Brands often check and measure drills on their own products, without focusing on the products of other companies. Most experts recommend buying equipment and accessories 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 a waste is 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 is the variety of working surfaces, the diameter of the holes being made and the engine power. An important aspect is the presence of a cooling system if you plan to use the purchased tool continuously.

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 to start work in this area, then he simply cannot do without a high-quality unit.
