Magnetic drill: what is it, how to choose and use?

There are many different tools. But it is very difficult to choose the most suitable among them. It is necessary to pay attention to one of the latest achievements - the magnetic drill.

Such a device helps:

• drill various holes;
• cut threads;
• perform manipulations with twist and core drills;
• make countersink and sweep in different conditions.

Structurally, the device is made so that it can work on any kind of metal surface.

The magnetic drill is used:

• at industrial enterprises;
• in the process of repairing construction and other special machines;
• in the construction industry;
• when installing various metal structures.

The electromagnetic drill adheres as tightly as possible to all processed surfaces. The force of pressing the soles to the surface ranges from 5 to 7 tons. This allows you to work quietly even under the ceiling. At the same time, unlike the widespread drilling machines used in industry, the mass of an electromagnetic drill is small. It can be easily moved, working on the facade, on the eaves of a building or other sheer surface.

The soft start function provides a quality, smooth start-up. Drills with a magnetic base have different operating speeds, adapting to the hardness of the material being processed and the specifics of the task. The smallest possible hole diameter is 0.1 cm.

The role of magnetic drills is great at facilities related to the production, storage, processing and transportation of hydrocarbons, as well as in the chemical industry. There, a high level of security is of particular importance. Since most of these drills are pneumatic, the risk of electric sparks is reduced to zero. A drill with magnets on the sole is capable of:

• prepare a flawless hole in a short time where it is difficult to reach with a hand or power tool;
• complete most of the tasks in the shortest possible time;
• achieve impressive performance;
• save electrical energy.

Since we are talking about a device that does serious work, designers care about reducing friction and increasing cooling of the working surfaces. For this purpose, a continuous supply of coolant and lubricant is provided. Since the reduction in friction allows the load on the motor to be reduced, the uptime increases. In addition, the cooling is 100% automatic and no special action is required.

It is appropriate to start a review of models of magnetic drills with a Russian development - "Vector MC-36"... This drill is lightweight and affordable. Thanks to design innovations, it was possible to solve the problem of fixing on uneven metal. The engineers were also able to ensure stable operation in rooms with low ceilings. The machine is completely protected from overload during operation.

The characteristic features of "Vector" are: low weight, ease of control, ease of moving to a new location; but there is only one fixed speed available. If you need the highest possible speed, use drill Extratool DX-35... This machine is capable of working with both classic twist drills and core drills. It is highly efficient and allows operators to set the desired pressure level. As in the previous apparatus, the supply of coolant to the working area is ensured; but for many people the price of the system will seem excessively high.

Simple and stable operating device - BDS MaBasic 200.

The characteristic advantages of this design are:

• easy mastering of the principles of work;
• optimal motor power;
• high speed of turns;
• the ability to perform work in hard-to-reach areas;
• the possibility of using twist or circular drills.

The chuck is completely standard, which ensures a stable fixation of the cutting attachments. If necessary, it is very easy to change cartridges for the correct size. The attractive power of the electromagnet is large enough to place the machine in an arbitrary location. Judging by the reviews, the device fully justifies its price. However, there are two weaknesses: the rigidly set speed and the lack of power during the cold season.

Element 30 Rotabroach - a mobile and relatively light device with a high power motor. Thanks to the improvement of the gearbox, the system is made more reliable, it can work longer. The power supply comes from a network with a standard voltage of 220 V. Along with high-quality assembly and decent overload protection, there is also a drawback - a small drilling diameter. But to buy the lightest magnetic drill, you must opt ​​for the Eco 30.

In addition to the reduced size, the ability to work in narrow aisles is ensured by the special design of the gearbox. The manufacturer guarantees that the magnetic attraction will be 1.2 tons. Despite the compactness, Eco 30 equipped with a very powerful motor, which is able to supply increased force to the twist drill. As a result, it can punch a larger hole. Judging by the reviews, the drill is equipped with a sturdy comfortable handle; which is important, consumers cannot name any significant negative properties.

From the very beginning, even before going to the store for a tool or before starting work, you should clearly understand: such equipment is intended only for manipulating metal. When choosing devices according to the degree of magnetic force, it must be borne in mind that the clamping force increases only with an increase in the size of the electromagnets. That is, a more powerful drill is always heavier and larger. In order not to buy an unjustifiably powerful and expensive structure, you should focus on the thickness of the metal that you have to drill.

Very unpleasant consequences arise if the drill gets jammed.

To avoid this:

• clean the place where the drill will be placed;
• carefully outline where they will drill;
• check the reliability of fastening the device;
• make sure there is a coolant supply in the tank before starting the drill.

When removing the apparatus from the base, first turn off the power supply to the pillow, supporting the drill so that it does not fall. When drilling non-magnetic metal, special vacuum base plates are used. As with any other drilling machines, it is required to check the serviceability of the case and the insulation of the wires before starting work.
