A set of construction equipment is indispensable without a tool that allows you to tighten a screw, hang a shelf, assemble furniture or carry out minor home repairs. An automatic screwdriver greatly simplifies and speeds up these tasks.
There is a huge selection of drills and screwdrivers on the market: mobile, networked, of different power, weight and size. Impact drills are considered the most versatile option. How they work and how they differ from impactless models will be discussed further.
What is it and what is it for?
The impact screwdriver has already gained recognition in the professional community, but it is not yet so widely known in the mass market. In appearance, this tool is similar to a conventional electric drill, the difference lies in the principle of operation. Hammerless drills operate using a gearbox, while screwdrivers of this type are equipped with an impact mechanism that increases torque.
The shock mode does not have a constant tempo, but is triggered when colliding with an obstacle. This gives the device a noticeable advantage when working with hard and particularly hard materials, such as concrete.
The purchase of such a tool is relevant for both home use and professional construction. Craftsmen note that the impact principle of operation does not interfere with tightening fasteners and does not damage the elements.
Which screwdriver is better: impact or non-impact?
To this day, the question remains relevant: which screwdriver, impact or non-impact, should you choose? This article discusses all the features, pros and cons of each of the listed types.
Rating of the best impact and non-impact screwdrivers
Differences between an impact screwdriver and a non-impact screwdriver, advantages and disadvantages
An impact screwdriver has advantageous advantages over its non-impact counterpart:
- Such a screwdriver makes not only circular, but also reciprocating movements, thanks to which it can drill in brickwork, concrete and hard wood.
- Increased load resistance thanks to the robust spindle.
- The tool is capable of pulling out even screws with worn edges or a damaged cross.
Kinds
Before classifying impact screwdrivers, you need to understand the division of tools into drills and screwdrivers. The former are equipped with drills for making holes, while the latter can additionally screw in fasteners. If a tool allows the use of different types of attachments, it receives a compound name, for example, “drill-driver.”
According to the method of power supply, electric and pneumatic tools are distinguished. But the latter are extremely rare and are used only in specialized enterprises (tire fitting, service stations). Therefore, we can assume that all screwdrivers are electric.
According to the type of connection, electric screwdrivers are divided into mains and cordless. The former are lightweight and convenient for use at home. Battery-powered models are indispensable when working on sites without the ability to connect to an electrical outlet.
Areas of application
The fundamental difference between impact models and standard ones is their compatibility with other devices. You can use a hole saw in parallel, and also replace the functions of a conventional drill to drill holes using special attachments.
An impact screwdriver is needed for minor repairs, fastening parts, and for drilling particularly durable surfaces. Many professional workers appreciate the lightness and compactness of impact models. At high rotation speeds of the drill, there is no damage to either the screws themselves or the fasteners. Manufacturers and stores offer a wide range of models, which allows you to choose a tool at a low price, which will help out both with minor household repairs and with active use in the workshop.
Distinctive features
When choosing between an impact and hammerless drill, it is important to understand the pros and cons of each option:
- Scope of application. Hammerless models are suitable for drilling metal, wood or plastic. When working with more durable materials (brick, concrete, stone), preference is given to impact tools.
- Operating mode. A non-impact screwdriver works only in two modes: drilling and tightening. The percussion model provides the ability to enable a third mode - percussion. It allows you to cope with particularly difficult areas.
- Accuracy of the result. According to this criterion, hammerless drills win. The spindle of the impact model is designed for work with heavy loads. Plus, most tools of this type do not have stops, which can lead to damage to the material.
- Weight. Impactless models are much lighter than impact models, which is more convenient for long-term work. At the same time, the presence of a striking mechanism helps reduce the load on the operator’s hand.
- Specifications. The main parameters are power and rotation speed. High twisting speed is typical for non-impact operation. Impact tools increase torque, making it easier to drill into surfaces.
What is the difference between an impact screwdriver and a non-impact screwdriver?
Whether to buy an impact or non-impact screwdriver depends on the purpose of purchasing the tool. The devices are very similar to each other, but there are fundamentally important differences between them.
What is the difference between an impact screwdriver and a non-impact screwdriver?
An impact driver is an improved version of a conventional tool, equipped with a pusher mechanism. In the process of drilling particularly dense materials, the device makes directed taps, making it easier to make a hole. You can turn on the special mode manually; in some models it starts automatically if the nozzle encounters an obstacle.
The breaker device puts less strain on the operator’s hands during operation and is very convenient for long-term drilling and screwing of fasteners. However, it does have its drawbacks. Namely:
- rapid wear of the fender mechanism;
- low speed of operation in special mode;
- lack of jaw chuck and torque limiting function.
The unpleasant difference of the unit is the price. If we compare models with a bumper with simple ones, the cost of the former will be noticeably higher.
A device with a special mechanism is designed primarily for tightening tight screws and screws. If desired, it can also be used to drill into concrete, brick or masonry. But the device copes with such tasks with difficulty.
Attention! Due to characteristic differences, the impact unit makes more noise than a regular one.
Using a screwdriver with a chipper, you can easily unscrew fasteners with partially erased edges and a damaged cross
As for the unit without a built-in hammer, it has a simple classic design. The device is designed to work with soft brick, wood and plastic; it is used for screwing in and removing fasteners and drilling small holes.
The shockless design has its advantages:
- affordable price;
- reliability of the design - breakdowns are extremely rare;
- possibility of installing a variety of attachments.
Non-impact models are not suitable for intensive drilling of hard materials. With their help, you can easily hang shelves on the wall or install a cornice above the window. But equipment that does not have specific design differences does not allow you to quickly make holes in concrete, stone and solid brick.
Which is better - an impact or non-impact screwdriver?
An impact driver or a simple screwdriver is better for the home - learning the differences between the tools helps you understand. If you need to perform light household work using the device, you should choose a regular device without a breaker mechanism. Such a unit will help in assembling furniture and hanging shelves and pictures; one of its pleasant differences will be its affordability.
For professional purposes, it is better to purchase fender models. They are universal, in some cases they can replace specialized drilling tools, and quickly deal with damaged fasteners.
When choosing a unit with a built-in hammer, it is better to give preference to models with a high spindle speed
Which is better - an impact or non-impact drill/driver?
When studying the differences between an impact screwdriver and a non-impact screwdriver, you need to take into account that there is also a drill-driver - a device that combines the capabilities of both tools. The mechanism is designed both for drilling surfaces and for screwing in fasteners. The differences between breaker models are in the design - a part is hidden in the body that makes frequent taps on the rotating drill.
This type of drill/driver has a higher torque. They allow you to very carefully and accurately make holes and tighten fasteners without deformation. It is worth buying a drill-driver with a built-in automatic hammer for your home if a conventional drilling device does not cope well with hard walls or dense wood.
Attention! The universal tool has low power. For professional work, it is better to buy a good drill and a convenient screwdriver separately.
Conclusion
It is better to choose an impact or non-impact screwdriver - it depends on the volume and complexity of the work to be done. For everyday purposes, the capabilities of simple devices are usually sufficient. Devices with a bump stop are often purchased by professionals.
How to choose?
An important selection criterion is the type of cartridge and its opening diameter. The chucks come in quick-release and key chucks. In the first case, the attachments are fastened automatically, and in the second, a special key is required for replacement.
The opening diameter affects the functionality of the tool: the higher it is, the greater the number of attachments available for installation.
Special attention should be paid to the maximum torque value. The higher the indicator, the faster and easier the drilling will be. Models with continuously adjustable torque are preferable, as this option helps avoid damage to materials.
Another useful feature is reverse rotation. It allows you to switch to twisting mode without changing the attachment.
When choosing a cordless tool, you need to decide on the type of battery. They produce models with lithium-ion and nickel-cadmium batteries. The first ones are the most popular in modern equipment. They are light, capacious, and can be recharged at any time. Disadvantages include high cost and rapid wear during operation at low temperatures.
Nickel-cadmium batteries have completely opposite properties. They are inexpensive, can withstand frost, are heavy, and require complete discharge before charging to extend their service life.
The choice is also influenced by the manufacturer and cost of the tool. The best brands include Metabo, Bosch, Makita, DeWALT and Zubr.
Function difference
Most screwdrivers on the power tool market today belong to the semi-professional class. This means that the equipment has improved qualities, but does not meet the requirements for professional devices.
Almost all manufacturers produce both powerful and simple models. The most popular impact driver is Makita. Bosch, Metabo, and among domestic brands - Interskol, Zubr.
A professional tool is distinguished by its ability to work without interruptions for a long time, high power, and quick replacement of equipment. This type of device does not require too careful handling and is distinguished by its endurance and durability.
Home screwdrivers are characterized by a more modest set of qualities. It should be said that in professional series of equipment there are also low-power types of products. For example, this is a Bosch Professional impact screwdriver with a 10.8 V battery. However, they are included in this group due to their high build quality, thoughtful ergonomics, and long working life. Such devices are indispensable, for example, in furniture assembly plants.
Operating rules
Before starting work, be sure to read the instructions. It describes all possible modes of using the tool. Remember to follow safety precautions:
- Setting the maximum torque increases the risk of injury.
- Do not change settings while the chuck is rotating. All changes are made before turning on the device.
- Keep track of continuous operation time. Severe overheating of working elements leads to rapid wear.
- Do not touch the working parts immediately after turning off the tool.
- Do not use the device for other purposes.
- When working, be sure to use protective glasses and gloves.
Manufacturer's choice
Choosing a drill/driver is an important matter; how the tool will serve its owner depends on the right decision. Popular manufacturers that have long established themselves in the construction market include Bosch, Hammer and Hitachi.
These companies are mainly engaged in the production of household models. They are inexpensive and the quality is generally good.

Develops professional models. The quality of such a tool is undoubtedly better, but the prices are sometimes too high.
There are also domestic manufacturers. And although the prices for their products are much lower, you do not risk the effectiveness of the tool. Its models “FIT-80014”, “DE-450ER/10” are also known. Another good option is “GardenLux CD14-22. The listed models are intended for household use. For professionals, Makita-4700 and Interskol DU800ER are suitable. Their cost can reach 20,000 rubles. The price of household goods is no more than 7,000 rubles.
Definition
A screwdriver is needed to tighten and loosen screws and small bolts. The power tool has a built-in mechanism that stops the rotation of the chuck at the moment when the resistance to this rotation reaches its maximum. This is a very important point because the mechanism prevents damage to the screwdriver mount. By the way, you should definitely take into account that the above mechanism is adjustable. Today there are two main types of devices: screwdrivers that run on electricity and models that run on a battery. Of course, the price of power tools varies.
DeWALT Cordless Screwdriver
To drill holes on various surfaces, you need a drill. It is widely used in construction, decoration, carpentry and installation work. An interesting fact is that the first electric tool for drilling holes appeared in the mid-19th century, and since then it has been constantly improved. A modern drill has two operating modes: normal and impact
. If in the first case everything is more or less clear. With a drill you need to drill regular holes in walls and wood surfaces, then in the second you should clarify a little. Impact mode is activated when you need to drill holes in stone or concrete, that is, on harder surfaces.
The influence of the BOSCH drill on
Drill
The main function of the drill. Drilling. However, if there is speed and reverse adjustment (which most models now have), it can also be used as a screwdriver.
However, they lack any mechanism to automatically prevent bit stripping.
Therefore, here you have to rely only on your hands and head.
At the training the verdict will be like this. Buy this if you are going to be mainly drilling. But keep in mind that sometimes it can also be used as a screwdriver. After all, this is in any case more convenient than turning it with a screwdriver.
