Bosch drills: model characteristics and subtleties of choice

Drill Bosch - equipment that combines high build quality, German reliability and durability. Devices of this brand are widely used in construction and repair work of any complexity. They are preferred by amateur and professional home craftsmen.

The family of Bosch drills is so extensive that everyone can choose a unit with the necessary technical characteristics and the required functionality.

Bosch was founded over 130 years ago in Stuttgart. It was discovered in 1886 by electrical engineer Robert Bosch. At first it was a small workshop that specialized in setting up electrical equipment. Over time, the company has gradually developed. In addition to setting up power tools, Robert Bosch began to repair ignition devices for motors. Later, Bosch began to independently manufacture power tools, refrigeration equipment, jigsaws and rotary hammers.

Today the company is considered the largest industrial concern located in Germany.

Its main areas of activity are to create:

• home appliances;
• communication devices;
• equipment for cars;
• production equipment.

Products are made not only in Germany. Today, its production facilities are also located in the Russian Federation, China, Spain and a number of other countries. Both household and professional equipment are produced under the Bosch brand.

Among all the equipment presented, you cannot find devices in the budget price segment. You will have to pay more for high-quality and reliable equipment than for similar products from other brands. The legendary drills from Bosch are no exception. Consider their pros and cons, types, and also learn tips for choosing and repairing.

Before buying any power tool, it is important to familiarize yourself with its advantages and disadvantages in order to be "fully armed".

All drilling equipment from the renowned brand is durable. Its long service life is achieved through the use of quality materials and components that meet the most stringent requirements. The durable body of the products guarantees the safety of internal components in the event of a drill falling or other mechanical impact.

Other advantages of the equipment include:

• light weight and compact dimensions, which ensure ease of use (when using such devices, the hands do not get tired for a long time);
• high productivity and accuracy of the tool, thanks to which large-scale work can be performed in a short time period;
• excellent ergonomics of control systems;
• optimal ratio of mass and power;
• a guarantee of at least 2 years.

Bosch drills are functional. Most models have additional options that simplify the work of the wizard. These include:

• automatic speed control;
• obtaining a constant speed (Constant-Electronic system);
• quick cartridge change (Auto-Lock system);
• motor protection against possible overloads;
• illumination of the working area (convenient when working in conditions of limited lighting or its complete absence).

Other advantages of Bosch drills include their prevalence - the tool can be purchased at almost any store specializing in the sale of equipment for construction and repair. In addition, devices are sold in many online stores.

These devices also have some drawbacks, as evidenced by the reviews of the owners. First of all, people attribute the price to the minuses. The cost of a power tool from a legendary manufacturer is 2 or even 3 times more than for other devices with similar technical characteristics. In addition, some users complain about the lack of a case (for some models) and arbitrary unclenching of self-clamping chucks when drilling dense products (hard wood or metal sheets).

The Bosch company is engaged in the production of drills for household and professional use. Visually, the first instrument is distinguished by its green body, the second - blue. Household models are designed for short-term work. It takes time for them to cool down the engine.

Professional tools are designed to carry out large-scale construction and repair activities. They are distinguished by their high power and performance.

Impact drills are intended for professional use. They are able to withstand high and prolonged loads. They can drill strong materials with impact mode, screw fasteners into wood, brick or concrete products.

When using a mixer with the help of such devices, it is convenient to mix various building solutions (no more than 10 liters at a time). All impact drills are designed with high torque.

Such devices work when connected to a 220 V network. They have a two-core wire protected by good insulation, which protects it from kinks and temperature effects.

The company produces most models of drills with a cable from 2 to 2.5 meters. Less often on sale you can find devices with a four-meter wire.

Drill equipped with a battery (lithium-ion or sodium-cadmium versions). Such devices are mobile. They can be operated anywhere, right down to the field. They don't need a network connection. Most models can operate in two-speed mode. One unique feature of Bosch cordless drills is the Hyper charge system, which allows you to fully charge the device in half an hour.

All devices are equipped with a keyless chuck, due to which the master can quickly change the drill with one hand.

Devices designed for drilling holes only. Most of the models have a reverse function and the ability to work in several speed modes, so that they can be used as a screwdriver.

Ball and roller bearings are used in the production of hammerless drills, which guarantees the durability of the devices.

This is a mini drill that is convenient to use in confined spaces or when you need to drill holes in hard-to-reach places. Differs in light weight, compact size. Such devices are equipped with an angular gearbox.

Due to the vast assortment, it is sometimes difficult for the consumer to decide on the choice of the desired model and purchase the best option for himself. Let's figure out what to look for when buying a drill.

When choosing equipment, it is worth deciding for which work the tool is being purchased.If you plan to use the drill infrequently or for a short time (the optimal time of continuous work is no more than 15 minutes), it is best to take a closer look at household models. Such devices are characterized by small weight and dimensions, weaker power and affordable cost.

For professional work, it is best to take a closer look at impact drills with a power of 1 kW or more.... With this tool, you can quickly drill a through hole.

The next parameter that you should pay attention to is the type of food. It can be from the mains or from the rechargeable battery. As a rule, stand-alone models are more expensive than electric ones. In addition, it is necessary to decide on the required set of additional functions.

The following options will facilitate the work of the wizard:

• reverse (reverse motion) - allows you to remove a jammed drill or use the tool as a screwdriver;
• clamps and stops - with their help it is easy to make a hole of the required depth;
• several operating modes;
• locking the lock button;
• the presence of a keyless chuck;
• backlight.

Compliance with the manufacturer's recommendations for the correct use of the drill is a guarantee of long and trouble-free operation of the equipment. Before using the tool for the first time, read the instructions.

• It is only necessary to carry out work when using correctly selected components. Otherwise, the risks of overloading the motor are high, which often leads to its premature failure.
• A household tool is allowed to operate no more than 4 hours a day, while the maximum continuous operation of the device should not exceed 20 minutes. Professional models are designed for longer use.
• The impact mode of the drill should be used less often than the main one. Otherwise keyless chucks will quickly become unusable and the chuck will need to be replaced.
• It is unacceptable to turn on the reverse mode when working with a blow.
• If you need to drill a dense material, you should first use a thin drill, and only then a thicker one.
• In order for the battery to serve for a long time, do not keep the tool on charging longer than the manufacturer recommends.
• Do not use a flexible shaft when using impact drills or high speed drills.
• When working, use sharp drills. They cut into the material faster and better, preventing motor overloads.

There are two types of drill breakage - electrical or mechanical. Signs of an electrical problem - no motor rotation, no speed control, or no reverse function. If the tool does not respond to switching on, the first step is to inspect the wire at the base and near the plug.

Damage to the cable often causes the device to malfunction. If the wire is intact, you should disassemble the device and check with an ohmmeter the performance of the start button, starting capacitor and motor windings.

Unlike electrical breakdowns, mechanical damage is much more common. Often, users are faced with the failure of the cartridge.With this malfunction, it is often impossible to remove the drill due to damage to the gear connection. In this case, you will need to replace the cartridge. The process is simple, even an inexperienced master can cope with the work. In most models, the part is attached to the shaft with a screw.

After the actions taken, the cartridge is removed, replaced with a new one and assembled in the reverse order.
