The drill belongs to the category of the most common universal construction tools. There is another device - a hammer drill. How is this device different from a drill? It is indispensable in the construction and decoration of premises. And although the design of the devices is somewhat similar, the principles of their operation are completely different.
In order for the work to be distinguished by a high level of productivity and convenience, the differences between the tools should be clearly understood.
This article will examine what is the difference between a hammer drill and a drill. Each device will be described separately.
How is an electric drill arranged?
An electric drill is often used for repairs. To understand the specifics of this device, you need to digress from the theoretical part and understand how it works in practice.
What are the features of a drill from a hammer drill? Consider the main parts of the device and their purpose in the drilling process.
- Cartridge Holds drill bits tightly to grind or tighten screws.
- Gearbox . Lowers the speed of the electric motor armature. Their number is tens of thousands per minute. The gearbox is a transmitter of energy from the chuck to the drill. The same gearbox in other models of drills performs a shock function. It is called the ratchet mechanism.
- An electric motor takes electrical energy 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 controls the engine speed. In different models of electric drill it is located in different places.
- Button to switch between normal mode and shock mode.
- Device case.
- Induction rings or chokes. They are mounted to smooth the frequency indicator of the current.
- The capacitor serves as a protector against interference in the electrical circuit, eliminates heat and sparks during the start of the operation of the electric motor on the brushes.
- Network cable.
Scope of a drill
Anyone who does not even understand the intricacies of repair work knows that the function of a drill includes drilling holes of different diameters in almost any type of material. If the tool has a percussion mechanism, then it is able to break through concrete walls. But the scope of the device is not limited to this.
A household drill is equipped with different types of drills, used depending on what type of material you have to work with. Drills differ in appearance.
The purpose of the drill
- For drilling a wooden surface, 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 will need drills with a high level of strength, which have a special design.
- When working with tiles or glass surfaces should be extremely careful. Instead of a flat hole, a chip can easily turn out. To solve this problem, another type of drill was invented - with the shape of a spear. It is designed for ceramics and glass.
- To drill holes of large diameter, drill bits such as crowns will be required.
- Impact drill works on the principle of a hammer drill. It has the strength of a concrete and brick surface, although it will never reach the level of performance of a puncher anyway. The tool is designed for work of medium difficulty. For these purposes, use drill bits.
- In order to grind the surface with a drill, a special nozzle in the shape of a circle is used.
- To clean the metal surface, a steel wire brush is put on the drill. If the wire is twisted, then the processing will come out draft. For finer stripping, a corrugated wire is required.
- To mix the mass, the drill is easily converted to a mixer. A special nozzle is also provided for this purpose.
How is a hammer drill?
What is the design of a tool like a hammer drill? How is this device different from a drill? The electrical circuit of the tools is identical. The main difference in the design of the hammer is in its percussion 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, since it has a high level of sensitivity to dust (the unit quickly deteriorates).
In turn, both species may have different structures.
There are designs based on:
- "drunk bearing";
- crank mechanism.
The first mechanism has a lower impact amplitude and is used in models of a punch for light work. The second is designed for units of medium and heavy levels of performance.
The latter type, as a rule, is intended for three types of work:
- drilling;
- hammer drilling;
- hit.
The principle of operation of the punch
The differences between the punch and the drill are as follows:
- Electric energy converted by the engine into rotational energy passing through the gearbox is transmitted to the “drunk” bearing or to the crank mechanism. They, in turn, contribute to the movement of the piston. A piston located in a hermetically sealed tube, from the air flow and direct impact energy, drives the ram. A moving ram transmits impact energy to the block. This is how the nozzle strikes the surface to be treated.
- The hammer drill differs from the drill in the presence of a special protective coupling. It is mounted in the tool on the basis of its design features, which consist in the absence of the possibility of turning the drill in the chuck when jamming. The coupling can dampen the rotation. This protects the master and prevents the tool itself from crashing.
- Also inside the punch there is an anti-vibration system and some specific details.
Punch purpose
The main purpose of the punch is to break up various materials. The tool, as a rule, is used by experienced specialists who have been working in the construction industry for more than one year.
The main functions of the punch:
- drill holes in concrete, brick;
- remove plaster;
- knock down a tile;
- to crack bricks;
- carry out gating of concrete walls.
This tool is extremely necessary when building a house and conducting repairs. It is very convenient to use, it works quickly and does not have a return.
Hammer drill bits
The main tool tips are:
- Boer;
- chisel;
- core drill;
- peak.
The chisel is placed on a punch during dismantling. Pica is used when gating walls before laying wires or to make a hole in the wall. A core drill can make a through hole of large diameter.
The equipment has a tail of two types:
SDS Plus device
It contains four oval grooves for mounting. Two of them are located at the end and are open, and two are hidden.
When the tail devices are inserted into the cartridge, it moves straight along the open grooves as along the guides. Special locking balls act as its clamps in closed holes.
SDS Max device
Contains five recesses for mounting. There are three open grooves, which provides a strong fixation of the drill. As a rule, such a system is used in devices of a professional level.
The difference between a punch and a drill from the point of view of the master
This article examined the difference between tools such as a drill and a punch. What is the difference between a percussion instrument and a drill from the user's point of view?
First of all, there is a difference in the main indicators. In an electric drill, this is the amount of rotation or torsion. And at the punch, power is revealed in the energy of the impact. It is measured in joules. The level of rotation of the drill is much lower than that of a drill with the same engine power. Therefore, asking which device is preferable, a drill or punch, is wrong. These are originally different tools.
The difference between the two units is also in the accuracy of the processing of the material. If you understand the structure of the hammer drill, then its abbreviation is SDS +. The use of this model of the cartridge caused the puncher to cease to be universal. Why did it happen? If we consider its drill, then it consists of a pair of straight lines and a pair of oval grooves. The first pair acts as rigid guides. Oval grooves fix the drill with a ball. But they are not so tough, and they have a certain slip. Due to this, the tip of the drill has an orbit of rotation. The longer the drill, the larger the orbit. With this configuration, there is no need to talk about drilling accuracy. Therefore, the hammer drill 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 resulting holes is unlikely to meet your expectations.
There is a configuration HR2450FT, which makes it possible to change the cartridge of the punch to a more suitable model, like a drill. The hole will turn out to be of better quality, but the wear of the main parts of the tool cannot be avoided.
The main operating mode of the drill is carpentry and locksmithing, characterized by a high level of accuracy, in use with materials such as wood, tile, etc.
What is the difference between a hammer drill and a hammer drill? The unit is designed to work with concrete and brick surfaces. Naturally, the duration and quality of work with various materials will vary significantly. The drill function of the drill is auxiliary and is designed for one-time use, and for a perforator, one-time use is drilling. If you do not adhere to the rules of use, then both tools will quickly fail.
Prolonged use of a punch as a jackhammer has a detrimental effect on the device, as does the shock 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.
Total
The article examined a drill and a hammer drill. The difference between a percussion instrument and a drill is understandable. If you intend to make redecorating at home with a single drilling of concrete or brick, it is better to purchase a drill. If you are planning a major overhaul, in which you need frequent knocking out of holes for the same electrical outlets, then you can not do without a punch. Ideally, the master should have both tools in his arsenal.
