Installation work both on the construction site and at home are inextricably linked with screwdriving and drilling operations. Such measures are required when installing equipment, finishing materials, laying communications, etc. In solving such problems, special power tools are used - a screwdriver and a drill. What is the difference between them? Despite working with different nozzles, there are not so many differences, but they are there. In many ways, the difference is due to the design features and functional content.
General information about the screwdriver
This type of power tool is designed for unscrewing and tightening screws, bolts and self-tapping screws. The main operational feature of the screwdriver can be called the automatic stop of rotation at the moment when the maximum resistance is reached. That is, when the hardwaretwists to the limit. What is the difference between a screwdriver and a drill in terms of a nozzle device? In this case, a bit is used, with the help of which the tool interacts with the screw by capturing its groove like a screwdriver. To work effectively with such a tool, it is necessary to initially choose the right rotation speed. Standard models of screwdrivers offer 2-3 speeds to choose from. The first maintains a small number of revolutions, but with high torque. This is the optimal mode for working with fasteners. Higher rotation speeds are for additional applications or non-standard screws.
Drill overview
Also a popular and in demand type of power tool in the construction market, the main task of which is drilling holes. In this case, drills of different formats are used as nozzles. Like screwdrivers, drills are provided with automatic control of the work process with the ability to stop it, but with a different principle of operation. For example, even lower-priced models have a stroke blocker in their design. Drilling often goes into a "wedge" when working with solid substrates. If there are such risks, then it is advisable to use a drill with a reverse (reverse stroke), which, if necessary, will allow you to remove the drill with minimal labor costs. By the way, multi-position models, thanks to the regulators, allow you to configure the device specifically for working with one or another material. The same torque adjustsspecifically for drilling metal, wood, plastic and even concrete.
Screwdriver Specifications
The strength of the electric motor is the main indicator of the working potential of this tool. Household models have a power of 300-400 watts, while for professional devices this figure exceeds 1200 watts. For battery versions, power is expressed in volts - for example, the Hammer ACD141B screwdriver is equipped with a 14.4 V power unit, and the maximum value for a high-performance tool of this type reaches 42 V.
Torque is also important in terms of fastener handling capabilities. It is expressed in rotational speed (Nm) and can reach 1235 Nm (Makita 6980 FDWAE model). It is worth emphasizing how a screwdriver differs from a drill in this indicator? In this case, the number of revolutions represents the limit torque. It can also be adjusted depending on the size of the screw. For drills, the emphasis is on the hole diameter, although the frequency ranges are on average equal.
Drill specifications
With regard to drills, it is important to take into account the speed of rotation of the cartridge. This is the number of revolutions that the spindle makes around its axis. In the middle segment, most models provide a speed of 4600 rpm - this value allows you to make standard holes for laying communications in everyday life. However, to create large-format holes, you cannot do without an impact function with a vibration impulse. For example, if a hammerless corded drill allowsmake holes up to 11-13 mm in solid bases, the vibration effect increases the diameter to 16-18 mm even in the domestic class. The power potential as a whole corresponds to the indicators of screwdrivers - 250-350 W. In choosing, the emphasis is placed directly on the size of the planned hole. The higher the power, the more options for mounting operations.
Functional support
Modern screwdrivers are equipped with the ability to adjust the torque, backlight, pulse mode and engine brake. What is the difference between a screwdriver and a drill in terms of a functional set? Many of their protective options and design mechanisms are similar due to the general principle of torque generation, but for drills, the presence of a reverse stroke is more important, since the probability of nozzle jamming increases. Also, premium versions support continuous drilling mode, which may be required when working with problematic materials. In this case, you will not need to constantly hold your finger on the start button.
Tool feeding system
Both screwdrivers and electric drills today are represented by models with different types of power supply. Traditionally, both categories of tools run from a conventional outlet - these are light and compact devices, but they are dependent on access to a power source. Moreover, for an impactless corded drill, compactness and lightness are fundamentally important, since the degree of pressure on the part of the user is required to be small.
Availabilitybattery pack eliminates the need to connect the device to a power outlet, but increases the weight and dimensions of the tool. As a rule, rechargeable batteries on lithium-ion or nickel-cadmium cells are used as a source. On average, cordless drills and screwdrivers can work autonomously for 45-60 minutes. For ease of use, many manufacturers include a spare power supply in the kit, which can be used while the main battery is charging.
Drill driver features
The popularity of multifunctional devices that combine the functions of drilling and screwing hardware is growing. If the tools in question with one of these functions are designed for serial operation in one mode, then the drill/driver is optimally suited to the master wagon, whose activities are related to various technical operations. It is important to keep in mind that the design of a multifunctional vehicle is heavier, more complex and almost always requires battery power, which ultimately affects the reduction in maneuverability. As for the expansion of functionality, for example, the Makita DF457DWE drill driver is provided with a two-speed gearbox, thanks to which you can fine-tune the torque for different drilling and screwing operations (choice of 16 steps). Added to this is the presence of a keyless chuck that allows you to quickly change nozzles.
Tools and consumables
For a complete workflow, you will need bits for hardware suitableformat and drill for holes. As a rule, the tools of both groups already come with tooling sets in the basic configuration. What is the difference between a screwdriver and a drill in terms of additional support? It is important to consider personal protective equipment and opportunities for dust removal when it comes to using a drill. The fact is that drilling in concrete structures is accompanied by the release of large volumes of construction dirt. In this case, impact models have a special pipe for connecting an industrial vacuum cleaner, which directly sucks in the outgoing dust during drilling. It will also not be superfluous to prepare protective equipment - glasses, earmuffs, gloves and a respirator.
Conclusion
Drills and screwdrivers are indispensable helpers in the household of those who periodically perform construction or repair work. And it can be not only operations related to drilling and fasteners. Thanks to the attachments, both tools are also capable of cleaning and polishing surfaces. In terms of price, the difference between them is small. An average Hammer ACD142 14.4 V screwdriver with two batteries is available for 4 thousand rubles. Approximately the same is worth the appropriate power drill. And again, it is worth emphasizing that the differences between the two categories of power tools are increasingly blurred against the backdrop of the emergence of multifunctional models. They perform tasks of an expanded spectrum, supporting and impact function with a slotting of solid structures. This feature brings drills and drivers closer toperforator segment.
