A bit of history

A hand drill was invented back in the Neolithic Age. Originally it looked like a combination of ancient instruments. Due to the rotation of the bow, a drill was rotated, which was pressed by the hand from above. So they obtained fire, made the necessary tools, processed stone, wood, etc.

In the late nineteenth century, after the "taming" of electricity, an electric drill was invented . To date, the industry produces a mechanical, wire (network), as well as a battery tool.

The manual mechanical drill is designed for drilling holes not exceeding 10 mm. It consists of a spindle, on which small gears are mounted in a certain manner, and handles that move the mechanism.

What is the difference between the two-speed manual drill? When drilling its "driving" gear is connected to either another gear wheel or a bevel gear. Depending on the type of connection, the number of revolutions varies. This type of drills is widely used in production. This tool, which has two modes of drilling, allows you to choose the speed to work with different surfaces. For example, a hand drill with a feather drill will make a hole in the wood of 30 mm, and at a sufficient torque it allows to make holes in brick or concrete walls.

It can easily screw up or unscrew screws or screws, mix shpatlevku, paint, etc. Therefore, a person who buys a two-speed tool, gets a whole "team" of assistants.
