A handyman screwdriver?
This type of drill, equipped with a pistol grip and trigger control, combines the usual drilling function with that of unscrewing and screwing screws. In reality, these tools are mainly designed for screwing and unscrewing and, within certain limits, also work as a drill, although compared to types with lower power. Therefore, if you are looking for a hammer drill for drilling concrete or a dowel, this type of tool is not for you. Due to their ease of handling, often with one hand, they are also light, which makes them incompatible with great power.
What should I do before buying the screwdriver drill?
All DIY enthusiasts find it very useful to use the electric drill to unscrew and screw. And above all, they know very well how much effort and time you save (especially when you have to mount something with your arms raised) in the assembly of a piece of furniture, the fixing of a shelf … Before buying, it is recommended to carefully evaluate the technical characteristics, the power in terms of watts, the number of volts offered by the battery, the time required for charging.
The power of the screwdriver?
Most of these devices are powered by a rechargeable battery, although there are also screwdrivers with power cable, the absence of a cable is a plus, as it allows you to work comfortably and safely. You don’t even have to worry about the fact that if you go up or down the ladder and pull the cable, the plug can be pulled from the outlet. A drill that needs an electrical cable to operate also has the disadvantage of depending on the proximity of an electrical outlet and having less freedom of movement than battery models which are completely cordless.
The lithium batteries in the drill?
The best rechargeable batteries supplied with a drill, screwdriver, and unscrewer are lithium-ion batteries, which are characterized by their lightness and performance, which are also subject to the “memory effect” and which have a relationship between autonomy and much better recharge time than other batteries. The absence of the “memory effect” means that the tool can always be used with maximum power even if it is partially loaded, until it is completely exhausted.
Other types of screwdriver drill batteries?
Another type of battery supplied with these devices is Nickel-Cadmium (NiCd). This type is quite common, especially in the most economical models, because it requires less maintenance and is less prone to damage, but it is the one that has a greater predisposition to the memory effect, which makes it qualitatively less efficient. The nickel-metal hydride (NiMH) battery has intermediate performances between the lithium battery and the NiCd battery. Compared to NiCd, it has greater autonomy and is less subject to the memory effect, but the performance is lower than that of lithium, which remains the longest.
To evaluate the performance of the battery, the values to be taken into account are the power (expressed in Volts) and the autonomy (which is expressed in Ampere-hours, with the symbol Ah). According to the type of work to be carried out, those who use the screwdriver continuously cannot do without having a device with batteries of at least 1.5 Ah. In reality, although these data are included by the manufacturers in the technical specifications (with the battery recharge time), it is difficult to judge whether the theoretical value then corresponds to the real value, since there are several other variables such as the frequency and intensity of use. For domestic use, the required voltage can be 12-14 Volts. The most common voltage of a lithium-ion battery is 18V, because it is a power suitable for medium and large applications: for wood, walls, concrete, plasterboard or for drilling metal plates of limited thickness. You can also find models with a battery voltage ranging from 9 to 36 Volts. A 9-volt drill can be suitable for small jobs (it ideally replaces the conventional screwdriver), while a more powerful 24-36 volt drill is necessary to drill concrete. In this case, however, you are already entering a more powerful and bulky drill, which almost loses its function as a screwdriver.

The speed of rotation of the screwdriver?
The speeds are also defined according to power. A good drill and a good screwdriver must be able to adjust variable speeds which make it possible to adapt the number of turns to the material to be drilled or to act gradually on the screws to be loosened or tightened. Professional models can have up to six-speed selections, for a model intended for the home hobbyist, three are sufficient. The rotations per minute vary from 600 to 2000 rpm. Depending on the use of the drill and the type of material to be machined, the most appropriate model will be chosen: a fairly powerful quality machine must reach at least 1000 rpm. Medium-high speed drills offer 1200 to 1800 rpm.
Functions of the piercing screwdriver?
Regarding the performance of the screwdriver, it is necessary to assess the presence of two fundamental elements: reversibility and maximum tightening torque The reversibility function allows you to reverse the direction of rotation of the drill: a good electric screwdriver must allow not only to tighten but also to unscrew or correct any errors or inaccuracies in tightening. The maximum tightening torque is an index of the force applied to the screw, and is always expressed in Nm (i.e. say in newton per meter). Connected to the tightening torque, in the most efficient models, there is the adjustable clutch, which is used to turn the engine idle when it has reached a certain effort (i.e. the maximum in the screwing). The adjustment on the spindle is done by choosing from a series of positions which, in the most sophisticated models, can go up to twenty. The presence of a self-closing spindle instead of a rack spindle can also be an important factor for technological quality. Some models have both in dual drilling mode.
Ergonomics of the screwdriver?
An important factor in choosing the best equipment is handling: an ergonomic handle is important for working well. The handle should be comfortable, flexible and preferably covered with non-slip materials, to allow a secure grip even with sweaty hands. Size and weight also have an impact on handling and performance: too heavy equipment will tire quickly hand, too light equipment will not exert a certain force. It is advisable to choose models that weigh no more than two kilos in total, always keeping in mind that the lighter and more compact types are suitable for less complex everyday work, while those with higher performance will require necessarily a more robust construction.
Accessories for screw drills?
Among the accessories, we can cite the presence of a carrying case, a case to attach to the belt when the drill is not used momentarily, and an additional battery to have, already charged when the first is sold out, equipped with bits for drilling different materials and screwdrivers for screwing (also called bits). The more there are, the better!
Any opinions on the screw drill?
A good drill screwdriver should be built with quality materials. Good plastics and metal alloys can guarantee the durability of the tool over time, also taking into account that it could be stressed when working on very hard materials. The assessment before purchase must relate to the actual operation of the tool in terms of performance, in the two operating modes taken separately. It is, therefore, necessary to evaluate the features offered by the drill and those offered by the screwdriver; it is good to take into consideration all the conditions of use on the most different materials, even if it is clear that if you buy these power tools to drill a hard material, like stone or concrete, it is better to orient the choice towards a hammer drill. If the main function of the impact drill is to then assemble wood or metal materials, we will be interested in evaluating the action of the drill only on these two materials. When evaluating the maximum drilling diameters, an average electric drill should have a diameter of at least 20 mm for drilling wood and about 10 mm for steel or other metals.
