Arriving at the store building construction power tools, you can see his huge selection. When buying a screwdriver, your eyes can just run up – an abundance of models that have their own characteristics and different prices can confuse anyone. Let’s take a closer look at the selection process and determine the most important parameters that should be paid attention to..
Getting to the Choice
From the very beginning, it is necessary to determine the work that will be carried out with the help of a power tool. This will help determine whether you need to spend a substantial amount on the purchase of a professional screwdriver or whether you can limit yourself to buying a household model. The devices of the first type have high power, a large number of functions and a resource of work. Their torque can reach 130 Nm, which makes it possible to make holes even in solid materials. In household models, this indicator is usually 15-20 Nm. On the other hand, a household screwdriver will be enough for housework.
What else to consider
The next important indicator is the power source. The modern market offers cordless screwdrivers and network-powered devices. Models of the first type are not tied to the presence of electricity and wires. Batteries are nickel-cadmium, lithium-ion and other types. Lithium-ion products are environmentally friendly, but at very low or high temperatures they stop working. Nickel-cadmium analogues can withstand 1000 charges, but cadmium is toxic and can be harmful to human health.
At the same time, the Skil cordless screwdriver and other networked models usually have more power. When the battery is worn enough, you will have to recharge it very often. To network tools this flaw is unfamiliar.
The disadvantages of cordless screwdrivers are:
• when the battery is low, power decreases, the quality and comfort of work are lost;
• the use of the battery leads to an increase in the weight and size of the tool, the convenience of working with it decreases, if you have to work for a long time, your hand quickly gets tired;
• when discharging the battery, you will have to take a break and wait for it to charge;
• over time, the battery charge will decrease, as well as the duration of work with it.
