The construction and industrial equipment market is represented by a large selection of various equipment. Machine tool manufacturers regularly update catalogs with new, improved devices.

All machines responsible for the formation of holes are divided into models, where the feed:

• manual typewhen the unit is turned on through the efforts of the user - rotation of the steering wheel;
• automatedthat comes into action by launching certain systems.

The second option increases the drilling speed by 30%, which makes the equipment more popular.

Devices are divided into the following types.

1. Vertical... The spindle is located in the corresponding plane relative to the main structure.
2. Corner... A special type of portable machine tools with a horizontally placed motor. The motor is connected using a bevel gear and a vertical spindle.

The second option makes the device more compact, which gives access to drilling holes even in low rooms.

A standard classification in which all manufactured models are divided.

• Electrical or electromagnetic. The most popular type of drilling equipment, the use of which is possible almost everywhere where there is no particularly dangerous mode of operation.

• Pneumatic... To turn the device into operation, the energy of compressed air is used - the easiest way. The equipment is installed mainly where it is impossible to use electrical units. Also, the machines are in demand for work in places of increased danger, where it is necessary to comply with special requirements. This is explained by the type of structure assembled from alloys that prevent the formation of sparks when parts interact.

• Hydraulic... The principle of operation is based on the use of a hydraulic motor with a plate, which, thanks to the compressible oil, forms the required pressure. To assemble the structure, manufacturers use anti-corrosion alloys, which opens up access for installing machines in rooms with high humidity.

Despite the variety of models, all machines tend to heat up during operation without interruption. Therefore, modern devices are additionally equipped with a cooling system, which implies exposure of heated parts to a large amount of water stored in a special compartment.

The construction equipment market is represented by a large selection of magnetic drilling machines. Among the wide variety of manufacturers, it is worth highlighting several of the most demanded companies.

When purchasing equipment for forming holes and performing other technological tasks, it is worth considering the need to purchase additional elements. Some accessories extend the functionality of the devices. Among them:

• Coolant designed to extend blade life by reducing frictional force;
• capacities of various volumes;
• magnets for rotating the device;
• vacuum installations;
• cartridges;
• core drills.
• taps.

Additionally, experts advise taking into account the material from which the blades are made.

1. High speed steel. Suitable for purchase if you plan to create holes up to 35 mm in diameter or require processing of low strength material.
2. Solid carbide drills, cutters. Suitable for making holes larger than 35 mm. The blades are additionally used for processing materials with high strength characteristics.

Buying a magnetic drilling machine for processing pipes and other products requires a responsible approach and taking into account the following criteria.

1. Dimensions of the structure. Large models are installed in large-scale factories. In turn, small machines are useful for making holes in hard-to-reach areas.
2. Sole size... One of the important parameters that will determine which workpieces the installation can work with.
3. Installation type. Manufacturers produce devices with horizontal and vertical installation. Before choosing machines, it is worth clarifying how best to install the equipment.
4. Electric motor type. Power determines the drilling capabilities of the unit, so this point cannot be ignored.
5. Spindle type and cutter rotation speed. The higher the indicator, the better the quality of material processing. At the same time, experts recommend giving preference to models where the speed can be adjusted.
6. Drilling diameter. Magnetic machines have a maximum and minimum diameter of the hole being formed.
7. Maximum allowable head force. Considering this criterion will reduce the risk of unexpected device failure. The presence of a system that takes into account the pressure will allow the equipment to be shut down in a timely manner if it starts to work above the maximum loads.
