Ranking of the best reliable rock drills in 2020

A reliable punch is a useful power tool and an indispensable assistant for apartment renovation, when installing a kitchen set or TV hanging system.

Professional builders consider the rock drill to be a key tool in their work. At the same time, the mechanism should have extended functionality, increased reliability and power. Which company models are better suited to the requirements of a home craftsman or builder? How do you choose the options and important metrics you want?

So that the unit does not disappoint when buying, and cope with the available size of work, several important selection criteria should be considered. First, determine the nature and scale of the cases, then look for a model that is suitable for the price and characteristics.

Types of punchers

1. Networked is the most common type.
2. Rechargeable - The battery is located directly on the instrument. Convenient for operation without mains power, but the battery requires a full periodic charge after prolonged use.
3. Pneumatic - used in humid or unsafe gas environments.
4. Gasoline - suitable for long road works.

What does the tool do?

The difference between a drill and a hammer drill is that its main function is chiselling. The electrical appliance produces a strong accentuated blow, therefore it is indispensable in a number of construction tasks, and in home use:

• dismantling of building structures made of brick, concrete, stone;
• cleaning walls and floors from old ceramic or plaster coatings;
• drilling complex holes for fasteners in different materials: concrete, wood, metal;
• drilling sockets for electrical fittings, or through channels for pipes, cabling;
• can be completed with a "Bulgarian" grinding wheel and quickly cuts shafts - channels for placing electrical wiring or wiring;
• mixer for the preparation of mortars - supplemented with a special spatula;
• drills holes like a conventional drill, with the appropriate equipment.

How is the hammer impact force generated?

The operation of the mechanism is based on impact and torque. Depending on the mode, the efforts can be combined or produced separately. The electric motor generates torque to the pneumatic structure. It can be vertical or horizontal, and differing in the principle of transmission of motion to the working piston of the cylinder.

The vertical engine position is considered more reliable due to the improved cooling system and creates an increased shock impulse. Professional devices are equipped with them.

The impact force is transmitted to the shank of the installed tooling, and the drill in a special chuck moves in the longitudinal-axial direction.

The chuck has side slots and grooves for a certain range of movement of the drill. Such a Special Direct Sistem, or SDS, has three options:

• SDS-plus - presented in the amateur or semi-professional instrument class. The shank has a diameter of 10 mm and has 2 splines and 2 grooves.
• SDS-top - the chuck type is used on powerful professional tools up to 8 kg, shank diameter - 14 mm, with 2 slots and grooves of a different geometry.
• SDS-max - found in the most powerful electrical appliances over 8 kg, withstands significant loads, and transmits amplified pulses. Diameter - 18 mm, designed for heavy drilling or dismantling operations.

When choosing a tool, it should be borne in mind that a standard cartridge is designed for one of these systems, therefore, the equipment must be of a certain type.

What to look for when choosing

Impact frequency and energy

These indicators directly affect the performance of the unit. If the impact force is insufficient, the tool turns into a conventional drill. Strength is expressed in joules. The weakest perforators have 1-1.5 J, powerful construction drills have a force of 10 or more joules.

The impact frequency per unit of time contributes to the achievement of the result within a certain period of time. The higher the score, the higher the productivity.

Punch operating modes

1. Hammer drilling is a basic function in all tools. It is carried out with crowns and drills with victorious tips.
2. Conventional drilling - no impact. Requires special tooling and replaceable chuck or adapter chuck. Such models are more expensive, but inferior in performance to a conventional drill.
3. Chiseling is a demanded function, but for small amounts of work. Heavy concrete and large volumes will damage your hobbyist power tool. Chisels are used that split and chip away strong materials.

Depending on the number of modes in the instrument, they are: one-mode, two-mode, three-mode.

Power consumption of the tool

It is not a defining parameter, since the difference in power consumption for SDS-plus (400-800 W) and SDS-max (1000-1200 W) rotary hammers is small. Only the heavy models for drilling large diameters use 2000 W of power due to the enormous frictional force during operation.

The number of speeds of the punch

Simple models have one speed, more expensive and intended for large-scale industrial operation - 2-5. This is a handy option when a low level is required for accurate and accurate drilling and fast chiselling for difficult surfaces.

Built-in protection systems

1. Overheating protection is important to avoid melting insulation and bearing deformation. When the temperature inside the case rises, the power is automatically cut off.
2. A safety clutch ensures safety.When the drill is jammed, it helps to avoid injury to the hands of a person, or overheating of the electric motor.
3. Anti-vibration protection in the form of special pads and damping springs on the handle dampen shocks.

Important additional options when choosing an electrical appliance

• "Vario-Lock" - a locking system for fastening drills, bits, peak in a certain position, which prevents the rig from turning during the chiseling process.
• Ergonomics - horizontal models are longer, easier to work with in narrow spaces, but the center of gravity is shifted to the handle. Vertical tools are more compact and balanced, last longer without interruption, but they are more expensive. The presence of anti-slip pads, an additional handle, and a long power cord greatly facilitate the use of the mechanism. It is important to consider individual convenience when choosing a model.
• Reverse - the function of switching to the opposite movement of the drill, for example, when it gets stuck in a wall.
• Start stopper button - convenient for long, monotonous work.
• Drilling depth stop - a special fixed rod helps to estimate the length of the hole made;
• The dust extraction system in the form of a corrugated hood collects debris inside, as a result of which small particles do not injure the eyes and respiratory tract. Vacuum models are useful for drilling holes in the ceiling.
• Case and accessories - manufacturers often supplement a handy case with a minimum set of accessories, a cartridge, and lubricants.

Buy power tools from the best manufacturers in specialized large stores. In retail departments, you can carefully examine the model you like, try it on your hand, feel how comfortable it will be to work with it for a long time.

In the online store, you can find a product cheaper, compare with other options for the price. It is important to understand that it is better to consider products of popular brands, with a guarantee and an extensive service network, for ease of maintenance and repair. And the average price can differ greatly, depending on the class of the mechanism and its functionality.

There are foreign and Russian manufacturers on the market that have established themselves as excellent quality and inexpensive perforators in comparison with foreign counterparts.

Our overview of mechanisms in different price categories will help you navigate when buying the right and optimal model of power tools.

As a conclusion

To increase the service life, follow these simple rules:

1. Use only a serviceable device. Stop the chiselling process if strange noises and interruptions appear. Otherwise, complete deformation of the mechanism may occur or injury may occur.
2. Lubricate the bit shanks before installing into the chuck.
3. Hold the tool at right angles to the work surface.
4. Protective work clothing.
5. It is impossible to take up the equipment after drilling, as it heats up to 90-100 ° C.
6. Use only sharpened, serviceable, undeformed attachments to avoid injury and tool breakage.
7. Store the unit in a case to protect it from dust and moisture.

Periodic diagnostics of moving parts and timely repair will allow the device to function throughout the entire service life, and even longer, and also reduce the risk of possible injury.
