The hand drill and its merry companions

The function of the Electric Drill is to open the hole, which is a process to connect different components.
The function of the opening hole is to open the channel for the connector, most of the time it is a screw (such as installing hooks, installing sockets, doing woodworking), sometimes it is a thread or other accessories (such as making jewelry).

Drill holes before screws are inserted into a component to avoid screw failure or material bursting.

Whether it is a hand electric drill, a percussion drill or a hand twist drill, the drill scrapes the surface of the object through rotation, so as to penetrate the object.
You need different bits for different materials and hole diameters.

The hand drill can also be connected to different batch heads, used as electric screwdrivers, and even hardcore cooking.

The steps to use it are also simple:
01 Clamping bit hand The front chuck of the electric drill can be rotated to clamp the bit or the bit head (screwdriver head).

03 Select steering through the forward/reverse lever button, select the desired steering, press the trigger switch to rotate. The speed of the speed can be controlled by pressing the depth of the switch.
