Hilti diamond core drilling rigs

Diamond drilling is an important part of construction and geology. This process takes a long time and requires the proper technique. Over time, the number of manufacturers of diamond drilling rigs has grown, and one of them is Hilti.

First of all, it is important to understand the purpose of diamond drilling. This process is needed, first of all, in the construction industry, because in this way you can create holes for pipes, which finds its purpose in laying water supply, heating, ventilation, air conditioning. In addition, diamond drilling is used in geology when working with hard rocks and underground formations. The power of this technique allows it to have a universal purpose in several areas of human activity at once.

The main tool is diamond core bits, which interact with installations, which are the main energy and driving force for the entire mechanism.

For a complete acquaintance, it is worth making an overview of the Hilti diamond drilling rigs. Thus, it will be possible to draw a conclusion about how high-quality this equipment is.

• Hilti DD 200 G02 - a machine designed for drilling holes. The best material for this will be concrete, for which the design of this drilling rig is designed. With this equipment it is possible to create holes of medium and large diameters from 35 to 200 mm. Built-in LED pressure indicator, designed to help beginners in this business.

There is an optional quick-release shank designed for quick bit change without tools. The presence of this function makes the operation more convenient and simple. There is air cooling, a reducer with 3 adjustable speeds and different modes. Power consumption - 3200 W, maximum number of revolutions in 3rd gear is 1160 per minute. Weight - 14.6 kg, fully assembled, it will be equal to 36 kg. Noise level - 93 dB, vibration - about 2.5 m / cu. cm.

• Hilti DD 350-CA - a powerful and expensive unit designed for a wide range of works, from simple use to the most professional tasks requiring high quality and reliability from equipment. Among the advantages it is worth noting a wide "spread" of drilled holes - from 52 to 500 mm. In this case, the basic material with which it is recommended to work with this installation is concrete.

There are only ten of them, and the 4th of them has the ability to reach the maximum number of revolutions per minute - 619. Input voltage is 230 V, sound pressure level is 95 dB, vibration can reach 2.5 m / cu. cm. The weight of the unit alone is 14.4 kg, while assembled - about 35 kg. The presence of a high frequency motor and an automatic feed unit makes this model reliable, efficient and resistant to heavy loads.

As for other units from this manufacturer, these earth and concrete drills differ in their characteristics and price. As a rule, the main criterion is to increase the maximum diameter of the holes to be drilled in accordance with the cost. This increases the power consumption and the number of speeds along with their revolutions.

It is worth mentioning the details required for the operation of diamond drilling rigs. The sump ring is necessary to ensure a seal while drilling into the material. Having a certain scale and dimensions, this spare part does not allow excess water to pour out. There is also a water tank containing the main liquid. It connects to a wet drilling kit.

In addition, there are various mounts that allow you to fix the unit in the desired position. Naturally, the main component can be called a diamond core bit. Its assembly and disassembly, change, as well as sharpening depend on the specifically selected model.

Quite complicated tools, such as diamond drilling rigs, need to be properly operated. This is primarily manifested in the observance of safety regulations. Let's take a look at a few of the most important points.

• Since the units are equipped with electric motors, make sure that the power cable and all mechanisms are in good working order. Any electrical faults can cause the unit to stop working.
• Keep your workplace clean, and use the equipment where there is no large amount of dust, dirt and explosive substances nearby. Staff must wear special clothing.
• When installing the units, make sure that all fasteners are secure and that the design is fully observed. It is advisable not to use the tool in rainy weather - if it is extremely necessary, then take care of the protection of the equipment.
• When using different speeds and operating modes, pay your attention to the fact that there is no overvoltage of the electronics, otherwise the equipment will consume its resource much faster. This can affect the durability of the equipment.
• If you are faced with a malfunction of the unit, then carefully inspect it, check the integrity of the structure. In the event of a breakdown, contact the technical centers where they can help you.
