It can be confusing or even frustrating to choose the best power tool to meet your needs. There is strong competition between the different brands of screwdrivers, whether Bosh, Makita, Hitachi or Black + Decker. These manufacturers regularly demonstrate new features and benefits, higher speeds and performance, and new batteries. We’ve put together this guide for you to determine which is the best cordless drill on the market for your budget whether you’re a simple hobbyist or a true professional.
The famous DIY brand offers its new model, the Makita HP457DWE10 cordless drill screwdriver with a complete box. Comes with a ton of accessories, this drill is designed for regular or even heavy-duty use. Its real strong point remains its light weight in this category of 18v drills.
User reviews show that it’s rare to be disappointed with one of the best brands of pro cordless drill on the market. The Makita HP457DWE10 is no exception to the rule with its power of 300W and the 16 possible torque positions for powerful and precise use.
Bosch Professional GSR 18V-55
The Bosch Professional GSR 18V-55 model combines all the advantages of a good professional cordless drill driver for a very good price / quality ratio. It is at the same time reliable, practical, versatile and compact.
The Bosch Professional GSR 18V-55 cordless drill screwdriver has a very good autonomy and is delivered with 2 Li ion batteries as well as a fast charger. It has a torque of 38 Newton meters for a maximum speed of 1400 revolutions per minute.
Einhell TC-CD 12 Li
If you are looking for a drill for occasional use without breaking the bank, the Einhell TC-CD 12 Li model may be enough. The French brand offers a tool that is easy to use but of ideal quality for plasterboard or even furniture assembly at home.
Very practical, the Einhell TC-CD 12 Li model has been designed for “Sunday DIY enthusiasts ” with 12V lithium batteries with good autonomy. Despite this low voltage, the maximum speed exceeds 1000 rpm and allows to offer a light drill of just over 1kg only.
How To Choose A Cordless Screwdriver?
If you are still in doubt, here are some important points to consider when choosing your drill.
Corded Or Cordless Screwdrivers?
As its name suggests, screwdrivers are tools offering at least the functions of drilling, screwing and unscrewing. The best cordless drills available on the market are extremely practical and powerful, allowing you to work with more mobility and freedom unlike corded drills. You can get away from the walls without worrying about the long wire that hangs around the various pieces of furniture or the need to install an extension cord. That said, you have to be careful to choose a reliable and efficient model because not all cordless drills perform well and you might be disappointed.
Choice Of Batteries
Lithium-ion batteries are becoming more prevalent in cordless tools at the expense of nickel-cadmium batteries which perform poorly when the tools are not used often. In addition, the composition of the Li-ion battery is much less toxic and environmentally friendly while providing higher power during its service life.
It is recommended that you have a second battery just in case to do your job faster and more efficiently even if the battery life is very good. Indeed, it will otherwise take about thirty minutes of recharging if you break down during the work. As with many tools, it’s cheaper to buy a kit with two batteries at the time of purchase rather than trying to buy an additional battery separately later.
Battery life is measured in ampere hours (Ah). A large capacity battery will generally run much longer than a smaller capacity, although our tests show that this is not always the case.
Power And Voltage
For cordless drills, wattage is the voltage of the battery and is measured in volts (V). Generally speaking, the higher the voltage, the better the torque and therefore the torque rotational force to overcome resistance. 18V is thus a sufficient voltage to drill large holes in the framework and the flooring for example.
However, our tests show that the right tension is not always enough to be a reliable drill. Indeed, we find that 18V drills vary widely in their drilling performance and torque.
Sometimes you have to find a compromise between performance and weight depending on your use. A 3.6V drill will be much lighter than an 18V model even if there are now good models combining these 2 criteria.
Note that my most cordless models today are equipped with a pistol-shaped handle to prevent hand slippage and to accommodate a battery. Since the battery is centered under the weight and mass of the motor, this type of non-slip grip provides better overall balance, especially in heavier exercises. In addition, they can more easily fit into tighter spaces as long as your hand is in line with the center of the drill.
For heavy drilling and driving large screws, a dual 2-hand grip lets you apply higher pressure to drill harder ways like granite. This is the case with chisel punches which often have an additional handle.
Speed And Torque
Most models therefore have 2 different speeds:
- A more powerful torque to drill holes in steel, tiles or concrete with a large drill, for example;
- A lower torque to screw / unscrew or make holes in a softer material and / or with a drill of a smaller diameter.
A slide switch allows you to select a high or low speed to perform any type of work. For carpentry work and complex repairs, opt for a drill that also has an electronic speed controller to avoid jump starts with lamp and lighting for more precision.
Located just behind the chuck, the adjustable clutch allows the drill drive shaft to rattle when a preset resistance level is reached. This allows you to maintain control so that you don’t damage or overdrive a screw. It also helps protect the motor when a lot of resistance is encountered when driving a screw or tightening a bolt. The number of parameters of the safety clutch varies depending on the model and can go up to 24 levels. With plenty of clutch settings, you can really fine tune the feed of a drill bit depending on the size of the screw you want to put in place. Finally, there are cordless drills with angle transmission and level for the most experienced users.
With the number of different drills on the market, it’s easy to buy the tool you really need. Choose the best cordless drill suitable for your use. You don’t have to break the bank to hang a few pictures, nor does it make sense to buy an entry-level model to burn out the engine after just a few days of heavy work. You should therefore think about all the possible jobs that you will have for your new tool.
