With a wireless, more efficient battery than ever before, it quickly became an integral part of everyday home DIY. Whether you’re installing furniture with a screwdriver function, drilling wood or metal with a drill, or drilling a wall to hang chandeliers, paintings or other accessories with a hammer drill function. But with the jungle of brands and products available, it’s not easy to navigate these days.
Currently, more than 40 brands offer cordless drills, each of which offers at least three different models. This is a different product with different characteristics to consider. Batteries are one of these very important characteristics. This is because the tool usage and performance (power (torque), autonomy, speed, etc.) can be determined from the information about the battery.For more information on this important component, see the article on lithium batteries.
What is the purpose of the cordless drill driver?
Cordless drill drivers are versatile power tools that can be screwed and drilled in most day-to-day tasks. It’s an essential tool for any handyman, whether it’s DIY, assembling furniture, hanging shelves, etc., and is also used by professionals.
Therefore, because it has a battery, it is wireless and has excellent power and various speeds to adapt to any situation.Can be used with screw bits, drill bits (bits and drill bits for wood, metal and concrete) hole saws, milling cutters and even metal brushes and grindstones.
Today, more and more cordless screwdriver drills are available. With the development of lithium batteries and our lifestyle, we need versatile, space-saving, and practical tools for different stages of our lives. Even professionals make this choice for their tools, and it is no longer unusual to see craftsmen work with you on this type of tool. The following is a list of examples of tasks that the cordless drill driver can perform. Screw-in / loosen all types of screws (flat, cruciform, Allen, Torx, etc.)
• Drill metal
• Drill wood
• Drilling tiles
• cordless drill with lithium-ion battery
• Assemble furniture
• Install shelves
• Hang a photo
• Grind metal parts
• Peeling, painting, rusting of parts
• Sand
• Deburring
Important features of purchase
Some points are important in a cordless drill driver and they make all the differences between good and bad tools!
Everything depends on your usage and your needs, but you can find all the information here for high quality and versatile tools that will last for a long time and will satisfy you in every projectincrease.
Percussion
Before knowing the other characteristics of a drill driver, it is important to know if it has a percussion function. This allows the drill / driver to drill through minerals such as plaster, brick, concrete, and soft stone.
Without this feature, drilling is limited to wood and metal. For this reason, the pinion system activates movements similar to those of a hammer. Therefore, it is added back and forth to the rotation.
1) Number of batteries
This accessory is of utmost importance when purchasing. For long-term work, having two batteries will allow you to work all day without a break to charge the battery. After all, with lithium batteries, the charging time is one hour, and models with one battery can be recharged during the installation of lunch on business days.
Everything here depends on your budget and the work you have in your outlook. Certain impact drill driver packs with two batteries are more interesting than additional purchases, although they can be purchased separately later.
You can check the battery charge status by pressing the battery button or trigger very useful before you start working see at a glance if the battery is still good enough to hold or if the battery needs to be recharged.
4) Transportation
• A box for transporting a drill driver, its charger, and its battery
• Comes with most models otherwise, count 20-40€ to buy a small case
• Battery
1) Battery type
The technologies used are: Li-Ion Lithium-Ion, Ni-Cd Nickel Cadmium, and Ni-MH NiMH. The latest technology available, Lithium-Ion is recommended here.
The battery has no memory effect, is light, recharges very quickly, and does not drain much unless used. Avoid Ni-MH and Ni-Cd batteries, which are heavy, have a memory effect and can take up to 12 hours to recharge.
2) Battery voltage (volt)
This is the power of the drill/driver the higher the voltage of the original battery the more powerful the device. Therefore, the battery voltage depends on the torque of the device. A drill driver without percussion should be at least 14.4V. Choose 18V for a good model or percussion model.
3) Battery capacity (at amp-hours)
This is a bit of battery life. The larger the capacity, the longer the usage time, but the charging time may also be longer. For the selected lithium-ion model, select the 1.5Ah model and the 2Ah model.
4) Charging time (minutes or hours)
On Li-Ion models, the quick charger typically recharges the battery between 15 minutes and 1 hour and 30 minutes. Most models charge in an hour.
Speed
Speed is also an important factor. This property groups the number of revolutions per minute available, the number of clutches, and the number of gears available.
1) Number of revolutions per minute
This value is categorized by available “speed” (or clutch, see 2 to be exact) and represents the number of revolutions per minute of the selected clutch. Rotational speeds are generally very similar on all models. The speed is 0 to 440 rpm for 1st gear and 0 to 1650 rpm for 2nd gear.
3) Number of velocities
Velocity is a pre-selection of torque and can be adapted to the task of performing rotational speed. Usually between 10 and 24 there is also a special speed for drilling that can give a screwing speed of 15 + 1: 15 and one drilling speed.
