The difference between an electric screwdriver and a rotary hammer

How an electric screwdriver differs from a torch?

In short, the main difference between an electric screwdriver and a drill and perforator. torque (which in an electric screwdriver is easily adjustable, but does not reach the speed of a drill and a rotary hammer, nor does it have impact force), as well as a quick brake (called the “coast brake”).

Electric screwdriver as a drill is used in repair work quite often, if only they are not associated with drilling holes in concrete and masonry materials If the drilling mode is not involved, the electric screwdriver as a drill will work.

Quality repairs without electricity

Trying to understand the difference between an electric drill and a cordless drill, then remember:

• Cordless drills have much more powerful high-voltage motors than their electric counterparts. So, if the owner needs to drive long screws or studs into a wooden board, the cordless tool is definitely needed
• Quality screwing of self-tapping screws and screws is only possible with an electric screwdriver. Here we are dealing with a lower speed, which is easy to control, especially important for craftsmen with minimal experience
• Regular power outages are among the top reasons to choose cordless units. They are convenient to use at the height of a three-storey house, in the attic and, of course, in rooms with old electrical wiring. In our villages, every fifth inhabitant faces this problem, and the natives of the village Tsminy in Volyn do not know what bright light is at all. Its functions here have been replaced by the usual kerosene lamps for ten years in a row. So answering the question of what is better a drill or an electric screwdriver with a quick-release drill chuck, without a doubt choose the latter option
• Convenience for construction and assembly procedures. Many electric drills weigh at least 4.5 kg, and long cords often interfere with work. If you consider this particular selection criterion, buy an electric screwdriver. In our store widely represented models of proven manufacturers, which can be purchased in installments
• For major renovations on a country house of 120 to 250 square meters, you definitely need a mains-powered machine. With it, you can work with fasteners of different lengths and diameters. In addition, to quickly screw in screws and work on hard surfaces. For minor repairs you will need an electric screwdriver

Power factor in drills and torches

The power of impact drills generally varies between 500 and 1050 W. The most widespread are versions with characteristics from 600 to 800 W, it is connected with their low cost. But for the more powerful models it is reasonable to prefer an inexpensive peorator: for a similar cost the efficiency of the impact force of the drill will be much lower.

The power range of horizontal rotary drills is 700 W to 1000 W, vertical up to 1500 W. The average value of the impact force is 3 J, and the top models of industrial class are even higher.

There is a misconception that the power is directly related to the performance of the torch. It is not uncommon for a model with a good power rating to be weaker during drilling than its less powerful counterpart. In addition to the number of watts, the quality of work is affected by the impact force, measured in joules (J). No less important is such a characteristic as the number of strokes per minute, it determines the drilling speed. All of these figures are always listed in the manual, and they are worth paying attention to.

When two tools with the same watts and joules are presented to the buyer, it is the frequency of blows per minute that determines the performance.

In a drill, on the other hand, power is the factor that determines performance. In addition, the higher the value, the more diameter it can drill, the longer it will be able to work without interruption.

Which is better? an electric screwdriver, a drill or a torch?

The question is which is better. An electric screwdriver, a drill or a torch. does not make sense 🙂 It depends on your needs. To install wooden windows, you just need an electric screwdriver. To hide the wiring in a concrete wall, you need a peorator.

Personally, I have a more or less decent electric screwdriver, which lasts for 3-4 hours, and a simple impact drill. they are enough for me for most work in my apartment and in my straw-frame house.

The main features of the screwdrivers are

an electric screwdriver is good because it does not weigh much, comes with batteries (usually two), and easily screws almost anything that needs to be screwed. The companies that make screwdrivers are huge, so there’s a wealth of choices.

There is also a distinction between household and professional screwdrivers. the latter have more powerful motors and batteries, they have a more powerful torque.

These are all the main differences. All three tools are designed to make holes. simply

All the other nuances that you see in catalogs and technical descriptions, of course, affect the price of the product and the additional convenience, but are not fundamental to the choice.

Drill and electric screwdriver: purpose, design and operating principles

Electric screwdriver description

electric screwdriver. a pistol-shaped power tool for tightening / loosening screws, self-tapping screws, screws and other threaded metal parts with slotted and hexagonal heads. For use at home and in industry for assembly / disassembly of furniture, fences, roofs. With special accessories for sanding surfaces and drilling holes. Electrical or battery-powered. some versions (pneumatic) operate on compressed air. The apparatus as a whole consists of the housing, the mounting unit, the mechanical and electrical parts and the adjustment and protection systems. Main structural elements:

• Plastic or metal housing with rubberized grip;
• The motor is an electric (pneumatic) motor that performs the rotation;
• planetary reduction gear: creates transmission from the motor to the spindle with a chuck;
• Adjustment coupling adjacent to the gearbox;
• The chuck for clamping the nozzles;
• electronic CU with a start button and reverse switch;
• Battery: present only in models with the same name.

The bit with a 6-facet shank is inserted and fixed in the chuck in advance; the torque is adjusted by a clutch (there are from 8 to 25 positions); the mains-operated electric screwdriver, unlike the cordless one, is plugged into a socket. Pressing the start button starts the motor, which through the planetary reduction gear starts to rotate the spindle with the chuck and bit. the stronger the force, the higher the speed. After screwing in the screwdriver, the rotational resistance increases, causing the ratchet to slip and the transmission to stop. When unscrewing hardware, reverse rotation is activated. the tool begins to work counterclockwise.

Drill Description

Drill. a manual electric machine in the form of a gun. Designed for making holes in wood, metal (steel), plastic, brick and (concrete). Used in construction and repair. at industrial and domestic level as a preliminary assembly work. Modern devices, except for direct functions, also “perform” work of grinder, angle grinder, mixer, mains or cordless electric screwdriver. Unit design:

• Plastic (or aluminum) body with rubberized handle and auxiliary handle;
• collector motor with stator, rotor, armature and brushes;
• Quick-action chuck that locks the nozzle (drill bit);
• Start button: Snaps into place when working for long periods of time;
• Speed regulator: adjusts speed depending on material to be machined;
• cord with plug for power supply;
• metal stop rod: controls the drilling depth;
• LED spotlight.

Start drilling by setting the depth stop and adjusting the speed: the harder the workpiece, the lower the speed. Grip the handle and press the “start” button: the direction of the tool must be in the axis of the hole in perspective. The spindle transmits the rotation to the gearbox, which drives the drill into a beam, angle, reinforced concrete foundation. the work is performed with technical care, because, for example, a Bosch or Interskol drill can reach speeds of approx. 1,300 rpm. plus/minus depending on the model.

How an electric screwdriver is different from a drill?

Now that you know the difference between a hammer drill and a rotary drill, it will be easier to make a choice. Choose this kind of tool after you have a clear idea of what you will need it for in detail. If you have to work with masonry and concrete, look in the store where a rotary drill is on the shelf. But if you want to drill into walls very seldom, it is not worth spending money on a high-powered drill. You can even get by with an impact drill. You only need one if you intend to do this kind of work often and for a long time.

A drill is designed for drilling holes in wood, ceramic tile, brick, metal, and other materials that are not too hard. You can also use the drill as a screwdriver. Concrete and stone are hard to hit with a drill. Because of low amplitude of impact the speed of drilling with a drill leaves much to be desired. Drills wear out quickly, especially on hard materials.

Different basic characteristics. In an electric drill, it is the amount of torque or torque. And in a peorator, what do you think? Here is what Wikipedia says: “The power of a peorator is determined by the impact energy (in joules).”. As you can see, they were originally designed quite differently. The torque on the spindle of a rotary table is much lower than that of a drill, with identical motor power. So asking which is better than a drill or a torch is like asking which is better than a fork or a spoon? They’re different.Mode of operation. This point is derived from the above point. The drill’s main mode of operation is high-precision carpentry and metalworking in such materials as metal, wood, tile, etc. д. Peorator is a machine designed to work with concrete and brick. Accordingly the time and the quality of the work with so different materials will be absolutely different. Т. е. the rebound function in a drill is auxiliary for one-time work, in a peorator the one-time work is drilling and rebounding (remember the three modes of the peorator). If these requirements of the manual are not met. rapid wear, costly repairs and reading the manual “when everything is already broken”.The difference between the drill and the peorator also lies in the accuracy of material processing. Let’s look at the chuck of the torch, its abbreviation is SDS. In fact, the use of this type of chuck has led to the end of the versatility of the peorator. Why? Consider the drill for the one. We have 2 straight and 2 oval grooves. The former “play” the role of hard guides. Oval grooves, there is a ball in the chuck to secure the drill, but it is not as rigid, with a certain sliding stroke. Because of that the end of the drill bit has an orbit of rotation, and the longer the drill bit, the greater the size of that orbit. In this state of affairs, what accuracy of drilling can be talked about? That’s why you can’t drill into wood or metal with the torch. previous point). And accuracy of drilled hole is unlikely to satisfy you.

Can you use an impact drill or overdrive as an electric screwdriver?

Impact screwdrivers can screw large-diameter fasteners into dense grades of wood. Therefore, some craftsmen are tempted to use an impact drill or peorator to drive large “drifts” into wooden boards and beams when building a house or repairing a roof. We will try to dissuade you from such experiments. The reason is that the inertia of the chuck (see “Inertia of the chuck”) is very low. answer to the previous question) plus the impact energy is a sure way to “miss. At best, you’ll just ruin the fastener and the material in which you try to screw it in with an impact drill. In the worst case, you could be injured by improper use of the tool, which is forbidden by the instruction manual.

And it is even worse with a peorator. Firstly, it has a different chuck (for SDS or SDS Max drills and bits) and the bit will not stay in it. Secondly, the impact force is so powerful that the screwdriver will break rather than turn. Therefore, this option should not even be seriously considered.
