How to choose a drill screwdriver - parameters and selection criteria

September 18, 2020

Every man who does any home repair must have a drill, which is a very handy tool for performing complex tasks.

Indeed, without this tool, it is practically unthinkable to carry out repair work and small construction works. For furniture restoration, hanging curtains or attaching shelves , a drill is the ideal tool.

In today's blog, we will tell you how to choose a drill driver that best meets your needs. At the same time, we will determine where the "golden mean" between price and quality lies.

How not to make a mistake when buying a knife

Keep in mind that when you go to the store, you should not only pay attention to the price of the device. Read the manual for the model you want, which will definitely indicate the most important technical characteristics of the device.

These are:

Rotation speed;
Battery type (if, of course, it has one);
Number of rotations.
Given these parameters, you should choose the tool yourself.

Professional drills or screwdrivers for household use ?

First of all, before answering this question, think about what kind of renovation and construction work you plan to carry out. Make your final choice based on this.

If you use the device only a few times, less frequently, then there is no point in buying a professional screwdriver . A battery-powered amateur, household model is quite enough for you, which has all the necessary functions and, compared to a professional one, weighs much less.

If you need to assemble something almost every day, then do not buy a very cheap model and it is better to opt for a powerful, professional model. As a rule, such drills and screwdrivers work with a power source and have an impressive size and weight.

Battery or cordless screwdrivers

There are two types of electric screwdrivers , one that runs on electricity and the other on batteries . The first option is a solid weight, which you can only work with in places where power lines are nearby. In addition, you can also buy an extension cord, which will be of great help if necessary. Cordless devices are lighter and the main important advantage is that they are autonomous.

It is not at all convenient to use corded models when working at height. In addition, they are so heavy that lifting them is even a bit problematic. Therefore, it is better to get to know battery-powered screwdrivers better.

Three types of batteries are used in drills:
1. Nickel-cadmium;
2. Lithium-ion;
3. Nickel-metal hybrid

Nickel-cadmium batteries are becoming more and more popular. Today, new drills are equipped with environmentally friendly Ni-MH cells, which are a bit more expensive. However, one drawback of these cells is that they are not designed for use in frost.
Batteries based on nickel-cadmium materials are more toxic, but their number of charges is twice as high as the previous type. Therefore, most of the tools presented in stores and markets are equipped mainly with Ni-Cd cells. They are also quite cheap and are not afraid of frost at all.
Lithium-ion batteries built into drills are rare. They are very sensitive to cold and, in addition, their capacity is low. The number of recharges is up to 3000.

In order to buy a good drill driver, or screwdriver as it is often called , it is necessary to pay attention to the type of battery, because keep in mind that the cost of the battery can be more than half of the tool. More precisely - from 60 to 70 percent.
