With cordless drills, screwdrivers and impact drills, you can work wherever you want. The network-independent and easy-to-use power tools not only screw in and out, but also drill in wood and metal. With today's cordless drill machines, you can even drill into stone.
A cordless screwdriver is easy to work with when you, for example, should screw in tight places or where it may be difficult to pull an electric cable, but in order for you to screw with a cordless screwdriver at all times, you have to put in the correct screw tool, so-called screwdrivers in the chuck. There are four types of bits for different screwdrivers: Track, Insex, Cross Track and Torx.
If you pull several screws one after another in, for example, wood, you can usually set the torque with different setting options that change slightly depending on machine technology . The machine then turns off automatically when the set value is reached. In this way, all the screws are pulled with the same torque. No screwed in too deeply. The speed is usually controlled by the power switch. It acts as a gas pedal on a car: the more gas you give, the faster it goes. This means that the harder you push the power switch on your cordless screwdriver or drill bit, the faster the machine will screw or drill.
Many cordless drills such as screwdrivers and drill bits often have a two-speed gearbox. It acts as a gearbox on a car: Low speed with high power on first gear, high speed and less power on others. By switching to the first gear you get higher torque.
In addition to the material, there are a few things to consider before drilling with a cordless drill:
- How big should you do? hole diameter
- How deep should the hole be?
- Small hole diameters: High speed
- Large hole diameters: Low speed
What drill you should use depends on the material you want to drill in. Thumb rule applies:
Wood, plastic, but also some metals: HSS drill. Setting: Drill Mode.
The most common drill bits are called spiral drill because of their appearance. A distinction is made between HSS drills (of high capacity steel) and concrete drill bits. In soft materials such as wood, plastic and aluminum, WSS type drill bits (weich = soft) are also used. In addition, there are a wide range of other drill types for special purposes. Drill bits or hole saws are used to accommodate large holes with a diameter of 25 mm and upwards. Drill bits are used when you want to drill a hole at the same time and make a recess for the screwdriver. Tile drills are used for drilling in smooth and brittle materials.
Brick walls are usually good to drill in but require a good cordless drill bit. In addition to a good impact drill, a good concrete drill is needed. The setting of the cordless impact drill must be in the drill position. Steel and other hard materials are machined with HSS drill type N (normal) or H (hard). Concrete drill has a carbide tip at the tip and is used for drilling.
When drilling, the drill slides slightly aside so that the hole becomes oblique or fails. Therefore, make sure that you constantly work exactly perpendicular to the wall or workpiece.
