Diamond drilling tools are professional equipment for working with reinforced concrete, concrete, brick and other hard materials. With such installations, you can drill both 10 mm (for example, for wiring under a socket), and a 1 meter hole (for example, for installing ventilation).

Main characteristics of the tool

Diamond core drilling equipment is ideal for making holes with maximum precision. This is one of the most important characteristics of the installation. The use of diamond equipment significantly reduces the amount of effort and time required to work. The prices for the instrument are also pleasing - anyone can buy it.

When drilling reinforced concrete structures using diamond equipment, the risk of cracks or chips in the drilling site is reduced to zero . Diamond drilling equipment allows drilling in monolithic reinforced concrete structures of different diameters.

The hole size also varies and is made according to the customer's requirements, and deformation of the concrete floor or wall can be avoided by holding the tool correctly.

The design of the diamond equipment is as follows

• The performance of the tool depends on the power of the engine.
• A diamond bit that is soldered onto the edge of the segment. The size of the crown depends on many factors, it is necessary to pay attention to it when choosing an instrument.
• Bed - a tool is attached to it, this part is used for accuracy and ease of work. It must be purchased separately as it is not included in the hand tool set.
• The handle that is needed to give direction to the instrument.
• The shank connects the spindle and the diamond bit.

The variety of work performed and the size of the hole to be made depend on the power of the engine. One of the important facts is that the equipment has several drilling speeds. Thanks to this, you can ideally select the drilling speed in accordance with the hardness of the material with which the work will be carried out. This tool facilitates the work, since during operation it can be tilted as it is convenient for a person.

There are three types of motors for diamond core drilling equipment:

• petrol;
• electric (110 V, 220 V, 380 V);
• hydraulic.

The operation of the diamond drilling rig is vibration-free, thus it is impossible to loosen the entire structure at the work site, which makes it possible to use the tool in various types of construction. Previously, during the construction of houses, ventilation windows were not always installed in the basements . This led to the formation of condensation due to temperature changes outside. This humid environment is great for mold and mildew growth. In order to prevent the growth of bacteria, it is necessary to make holes for ventilation of the basement. Diamond drilling equipment will cope with this task with ease and accuracy of 100%.

The power consumption of diamond drilling tools, depending on the power of the unit, ranges from 50 W to 7000 W . Drill speed - from 150 rpm to 4600 rpm. The material with which the work will be done determines the diameter and length of the diamond bit. The minimum diameter of the crown is 5 mm, the maximum diameter is 350 mm. Length from 25 mm to 1000 mm.

The parameters of the bits in this range make it possible to carry out drilling work both in heavily reinforced concrete and in asphalt.

Equipment types

There are several types of diamond drilling tools. The first is designed for the production of holes up to 120 mm and does not need a bed, since the equipment is made for manual work. The second type is designed for holes over 120 mm . A bed is attached to such tools, because without fixing the work becomes more difficult or impossible. The second type of equipment is wider in use due to the wide range of work that can be carried out with this tool, it allows you to work with a micro-shock.

Perforator

One type of drilling tool is a diamond core drill. If it is necessary to drill a small hole, then the hammer drill is indispensable, but as the size of the hole grows, the tool loses its irreplaceable properties . In this case, it is worth resorting to using other diamond drilling tools. The quality of the hammer drill depends not so much on the power as on the quality of the diamond core bits.

When working with high-quality diamond core bits, all quality standards of modern construction are observed . If the crown does not fit into the concrete, it must be replaced. It is undesirable to put pressure on the tool during operation, the hammer drill motor may overheat due to the increasing load. Frequent overheating of the tool will reduce tool life. If you hold it firmly in your hands, then this will be enough to drill a hole with a quality crown.

Hammer drill

The robust design of the drill guarantees a long service life regardless of the load. Impact drill sets include not only traditional drills, but also diamond core drills. They have the following advantages over conventional crowns:

• high strength - makes it possible to work with combined materials (reinforced concrete, reinforced concrete);
• ease of use;
• high level of accuracy.

The size of drill bits for diamond drilling in a hammer drill does not exceed 150 mm. The drill is equipped with a powerful motor and a good gearbox, which allows it to reproduce high torque at low revs, while having a strong impact mechanism. The number of revolutions and the number of strokes depends on the set speed. The working attachments are fixed with a strong key chuck.

Drilling with diamond bits is carried out both dry and wet.

Drilling rig

Drilling rigs differ from drills and rock drills in power, hole size and drilling equipment. There are different types of drilling rigs . When choosing a diamond drilling rig, one should be guided by the severity of the work performed, the hardness and thickness of the material being processed. The higher these parameters, the more powerful the setting we choose. Drilling rigs differ in installed stands of different types. The versatility of the bed makes work easier, especially if the bed has a smooth running gear. In this case, drilling is easy and smooth. Convenient folding of the bed makes it easy to transport the unit.

Drilling rigs are diamond drilling equipment installed on a separate self-propelled platform . Units with a hydraulic system operate in a rotary motion. Modern diamond boring machines are equipped with special programs to alert the user of the tool. When the motor is overloaded, the LED light comes on and notifies that it is worth stopping work. Most machines are equipped with SmartStart and SoftStart programs for smooth start / stop and hard rock drilling. SoftStart is a current limiting program whereby the tool only reaches full speed 2 seconds after being turned on.

Other

It is necessary to use different auxiliary devices for drilling rigs. Most diamond drilling equipment is supplemented with water cooling to keep the system from overheating . The pump must provide a continuous flow of water and pressure to the equipment, depending on the parameters of the technical equipment. One type is a piston pump. Such pumps pump liquid of any consistency, even with a high content of solid or viscous rock in the water. The pumps use a piston and three-piston system, which provide a certain pulsation when the flushing fluid is supplied. This allows the hole to be drilled as accurately as possible.

At the moment, both in Russia and abroad, they are switching to piston pumps . In connection with the transition to diamond wet drilling, which requires a small flow of fluid and high pressure, reciprocating and three-piston pumps are indispensable. It should be noted that in recent years, international requirements for the safety and reliability of mud pumps have increased. A water injection pump is used no less. The inside and outside of the tank is treated with polyester to prevent rust.

This pump is designed for autonomous water supply during drilling. It is enough just a few times to press the pump pump to continuously supply water and create the required pressure.

You will also need a catchment ring. Each diamond bit diameter requires a specific catchment ring diameter. It is indispensable for wet drilling. If dry drilling is used, a dust extractor with a vacuum cleaner will be a necessary additional tool. You cannot do without a stand for attaching diamond equipment. It is used to mount the motor and feed the diamond core bits. The stand is mainly used for making large holes. When selecting a rack, the characteristics of the engine must be taken into account:

• crown diameter;
• the ability to work at an angle;
• engine compatibility;
• drilling depth;
• type of base attachment.

There are several types of rack mounting

• Anchoring . The base is bolted.
• Vacuum mount . Possibility to attach a light stand to a flat surface.
• Spacer bar - the mount is held between two obstacles: the ceiling and the floor.
• Universal mount . Suitable for all kinds of diamond drilling equipment.

Usage Tips

Diamond drilling equipment is quite simple to operate, but it is still necessary to familiarize yourself with the rules of use and safety in the booklet that is attached to the tool. Experts give several tips that are not indicated in the instructions for use:

• before using the tool for the first time, let the motor run idle for a few minutes, this will make it possible to lubricate all the mechanisms of the motor;
• when drilling walls, ceilings and floors, make sure that there is no electrical wiring, gas or water pipe in this place;
• during operation, the diamond bit heats up a lot; during long and large-scale work, water cooling is necessary;
• when the crown is jammed in concrete, unscrew the equipment from the crown and use a reverse roll, you must not loosen the crown in different directions, this will lead to deformation and the impossibility of further use;
• work smoothly with the installation and do not overload the motor, this can lead to the destruction of the electronics, the cost of such repairs is quite high;
• pay attention to the condition of the carbon brushes that are near the engine - when they are erased, the work power drops, and further operation is impossible;
• flush all equipment well after finishing work.

It should be noted that, if the equipment is used incorrectly and safety procedures are not followed, there is a possibility of harm to yourself or others. During work, you should resort to several rules of safe work with the tool.

• Move to a safe distance for those who are not involved in the work process.
• Wear an approved safety helmet.
• Proven headphones will be required.
• Use approved goggles and a mask.
• Use a respirator.

According to statistics, more than 95% of accidents while working with such equipment occurred due to a negligent attitude towards their own safety. Be careful!
