What is the difference between a perforator and a drill in terms of functions and performance?

The drill is one of the most common universal construction tools. There is another device - a punch. What is the difference between this device and the drill? It is indispensable for construction and decoration of premises. And although the design of the devices is somewhat similar, the principles of their operation are completely different.

To ensure that the work is characterized by a high level of productivity and convenience, the differences between the instruments should be clearly represented.

This article will consider what the difference between a drill and a drill is. Each device will be described separately.

How is the electric drill built?

An electric drill is often used for repair work. To understand the specifics of this device, it is necessary to digress from the theoretical part and understand how it works in practice.

What are the functions of a drill from a puncher? Let's consider the main parts of the device and their purpose in the drilling process.

• The cartridge . Strongly holds the bit drills for grinding or twisting screws.
• Reducer . Reduces the speed of the armature of the electric motor. Their number is tens of thousands per minute. The reducer is the transmitter of energy from the cartridge to the drill. The same reducer in other models of drills performs the shock function. It was called the "ratchet" mechanism.
• The electric motor draws electricity from the network and converts it into rotational energy.
• The power button is needed to close and open the power circuit of the electric motor. The wheel on the button adjusts the engine speed. In different models of electric drills it is in different places.
• Button for switching normal mode to percussion mode.
• The case of the device.
• Induction rings or chokes. They are mounted to smooth the current frequency.
• The capacitor serves as a protector against interference in the electrical circuit, eliminates heat and sparks during the start of the electric motor operation on the brushes.
• Network cable.

The scope of the drill

Anyone who does not even know the intricacies of repair work knows that the drill function includes drilling holes of different diameters in almost any type of material. If the instrument has a percussion mechanism, then it can penetrate concrete walls. But this area of application of the device is not limited.

The household drill is equipped with different kinds of drills, used depending on what type of material you have to work with. Drills differ in appearance.

Purpose of drills

• To drill the surface of wood, special drills are used, but in most cases they use conventional models designed for metal. In some cases, pen devices are used.
• If you have to make holes in the metal, then you need drills with a high level of strength, which have a special design.
• When working with a tile or glass surface should be extremely accurate. Instead of a smooth hole, you can easily get a chip. To solve this problem, another type of drill - with the shape of a spear - was invented. It is designed for ceramics and glass.
• To drill large diameter holes, you need a crown type drill.
• The impact drill operates on the principle of a perforator. It can withstand a concrete and brick surface, although it will never reach the level of a perforator's productivity. The tool is designed for work of an average level of complexity. For this purpose, use winning drills.
• To use a drill to grind the surface, a special nozzle in the form of a circle is used.
• To clean the surface of metal on the drill is put on a brush of steel wire. If the wire is twisted, then the treatment will come out rough. For finer stripping, wire with a corrugated shape is required.
• To mix the mass, the drill can easily be converted into a mixer. A special nozzle is also provided for this purpose.

How is the puncher?

What is the design of such a tool as a puncher? What is the difference between this device and the drill? The electrical part of the tools is identical. The main difference between the design of the perforator is its impact mechanism. Let's look at this detail in more detail.

It should be noted that there are two types of shock mechanisms: electromagnetic and electro-pneumatic. The first type is not used often, as it has a high level of sensitivity to dust (the unit quickly deteriorates).

In turn, both species can have different structures.

There are designs based on:

• "Drunk bearing";
• Crank mechanism.

The first mechanism has a smaller impact amplitude and is used in the perforator models for light work. The second is designed for medium and heavy-duty units.

The latter kind, as a rule, is intended for three types of work:

• Drilling;
• Drilling with impact;
• Impact.

The principle of the perforator

Difference of the drill from the drill is as follows:

• Electric energy, converted by the engine into a rotational, passing through the reducer, is transferred to the "drunk" bearing or to the crank mechanism. They, in turn, contribute to the movement of the piston. The piston in the sealed tube, from the air flow and direct energy of impact, drives the ram. The moving ram transmits the impact energy to the block. This is how the nozzle hits the surface to be treated.

• The perforator differs from the drill by the presence of a special protective sleeve. It is mounted in the tool on the basis of its structural features, which consist in the impossibility of turning the drill in the chuck during jamming. The coupling can extinguish the rotation. This ensures the protection of the wizard and prevents the tool itself from failing.
• Also inside the puncher there is an anti-vibration system and some specific details.

Purpose of the perforator

The main purpose of the puncher is to break up various materials. As a rule, the tool is used by experienced specialists who have been working in the construction industry for many years.

The main functions of the puncher are:

• Drill holes in concrete, brick;
• Remove plaster;
• Knock down the tile;
• Chipping bricks;
• Conduct strobilenie walls of concrete.

This tool is extremely necessary when building a house and performing repairs. It is very user-friendly, works fast and does not have the payoff.

Nozzles for perforators

The main tool attachments are:

• Boer;
• chisel;
• Core bit;
• Peak.

The chisel is placed on the puncher during dismantling operations. The peak is used when strobing the walls before laying the wires or to make a hole in the wall. A core bit can make a through hole of large diameter.

The equipment has a tail part of two types:

• SDS Plus;
• SDS Max.

SDS Plus device

It contains four oval-shaped grooves for fastening. Two of them are located at the end and open, and two are hidden.

When the tail devices are inserted into the chuck, it moves straight through the open grooves as along the guides. Special locking balls act in the role of its retainers in the holes of the closed type.

Device SDS Max

Contains five notches providing fastening. The troughs are open type three, which provides a strong fixation of the drill. As a rule, such a system is used in professional level instruments.

The difference between a puncher and a drill from the master's point of view

In this article, the difference between tools such as drill and perforator was considered. What is the difference between a drill and a drill from the perspective of the user?

First of all, there is a difference in the main indicators. An electric drill is the amount of rotation or torsion. And at the perforator the power is detected in the impact energy. It is measured in joules. The rotational speed of the puncher is much lower than that of the drill with the same power rating of the engine. Therefore, to ask which of the devices is preferable, the drill or the punch, is wrong. These are initially different tools.

The difference between the two aggregates is also concluded in the accuracy of the material processing. If you understand the structure of the cartridge puncher, then its abbreviation - SDS +. The use of this cartridge model caused the puncher to cease to be universal. Why did it happen? If you consider its drill, it consists of a pair of straight and a pair of oval grooves. The first pair acts as a rigid guide. Oval grooves with a ball fix the drill. But they are not so rigid, and they have a certain slip. Due to this, the drill bit has an orbit of rotation. The longer the drill length, the greater the orbit. With this configuration, it is not necessary to speak about the accuracy of drilling. Therefore, the perforator is not intended for drilling wood or metal. For some time he will cope with this task, but do not use the tool for this purpose for a long time. The accuracy of the holes is unlikely to meet your expectations.

There is a configuration HR2450FT, giving the possibility of changing the cartridge of a perforator to a more suitable model, like a drill. The hole will be more qualitative, but the wear and tear of the main parts of the tool can not be avoided.

The main working mode of the drill is carpentry and plumbing work, which are distinguished by a high level of accuracy, in application with materials such as wood, tile, etc.

What is the difference between a perforator and a shock drill? The unit is designed for working with concrete and brick surfaces. Naturally, the duration and quality of work with different materials will vary significantly. The drill function of the drill is an auxiliary one and is designed for one-time use, while a perforator uses drilling as a one-time application. If you do not adhere to the rules of use, then both tools will quickly fail.

The continued use of a perforator as a jackhammer affects the device perniciously, like the impact mode of an electric drill. This is due to the heavy load on the shaft, the design of which is not designed for this function.

The result

In the article, a drill and a perforator were considered. What is different from drills percussion instrument, it is understandable. If you intend to do a cosmetic repair at home with a single drilling of concrete or brick, it is better to purchase a drill. If you are planning a major overhaul, which will require frequent knocking holes for the same electrical outlets, then without a perforator can not do. Ideally, the arsenal of the master must have both tools.
