What is a cordless drill?

Cordless drills work with rechargeable lithium batteries. Cordless drills allow the user to plug in the battery pack and operate the drill immediately without a power cord. A cordless drill is a versatile power tool because as long as the battery is fully charged, the drill can be used anywhere without having to work near an electrical outlet. Compared with traditional corded drills, cordless drills save a lot of money and are more convenient for people to use on the go or to do other drill work without power.

What is a cordless drill used for?

A cordless drill is a hand drill that carries its own lithium-ion battery or nickel-chromium battery and can be recharged repeatedly. It is suitable for use in the field or in places where there is no power supply because it does not require an external power source.

Cordless drills are mainly used to replace screwdrivers. These tools are used in combination with a drill, which is usually a rotary cutting tool used for punching holes. With the associated drill bit, the cordless drill can also be rotated counterclockwise, making it ideal for removing and drilling into screws. The right drill bits will vary depending on the task at hand, and they come in different shapes and sizes; the size refers to their diameter. Different types of bits and their suitable materials also differ, for example, twist bits for light metal, wood, plastic, metal, ceramic, and masonry; tile or diamond bits for masonry, and porcelain; high-speed steel (HSS) bits for wood, light metal, plastic, fiberglass, etc. Therefore, when using cordless drills, we need to make sure that the drill is compatible with the particular drill being used, even if they are of the same brand.

Classification and working principle of cordless drills

It is used for drilling, screwing in and out operations of screws, wood screws, self-tapping screws, etc. It can also be used for the drilling of various metals and wood.

According to the classification of the voltage size of the rechargeable battery block used, there are 7.2V, 9.6V, 12V, 14.4V, 18V, and other series.

According to the classification of the battery can be divided into two kinds of lithium battery and nichrome battery Lithium battery is more lightweight Battery loss is lower, and the price is higher than that of a nichrome battery.

The DC motor of the cordless drill rotates, and after deceleration by the planetary reduction mechanism, it drives the drill chuck to rotate to drive the work of the batch or drill bit. By pulling the positive and negative switch lever, the DC power polarity can be adjusted to change the forward or reverse rotation of the motor to achieve the dismantling and assembling operation.

Common uses of cordless drill tools

One of the most common uses of cordless drill power tools is to drill pilot holes in wood that may split. That's because screws have the potential to drill into the wood and separate the grain - especially if the screws are large. A cordless drill using a bit one size smaller than the screw's diameter can drill a pilot hole before inserting the screw, which helps reduce wood splitting. With a hole saw bit, the cordless drill can also be used as a hole saw for door handles, gutters, drains, and other round holes.

In addition, plasterboard installation is a common use for cordless drills. Installing the gypsum board requires lifting and securing large panels in place before inserting the gypsum board screws into double-headed bolts under the wall. That's why workers often carry cordless drills on their tool belts for easy access.
