A hand drill is a tool designed for drilling holes in various materials: wood, metal, etc. A drill is used in this unit, which is clamped with a special cartridge. Today, the industry produces various types of drills. This article describes these differences, allowing you to determine which tool is right for you.
A bit of history
The hand drill was invented in the Neolithic era. Initially, it looked like a combination of ancient instruments. By turning the bow, the drill rotated, which was pressed by hand from above. This is how they made fire, made the necessary tools, processed stone, wood, etc.
At the end of the nineteenth century, after the "taming" of electricity, the electric drill was invented. Today, the industry produces mechanical, wired (networked) and battery tools.
Drill manual mechanical designed for drilling holes not exceeding 10 mm. It consists of a spindle, on which small gears are installed in a certain way, and a handle that sets the mechanism in motion.
What is different fromthe rest of the two-speed hand drill? When drilling, its "driving" gear is connected either to another gear or to a bevel gear. Depending on the type of connection, the number of revolutions changes. This type of drill is widely used in production. This tool, which has two drilling modes, allows you to choose the speed to work with various surfaces. For example, a hand drill with a drill bit will make a 30 mm hole in wood, and with enough torque, it can make holes in brick or concrete walls.
Benefits
Hand drill is an indispensable tool for those involved in construction or repair. It will easily screw or unscrew screws or self-tapping screws, mix putty, paint, etc. Therefore, a person who purchases a two-speed tool acquires a whole “team” of assistants. This is, first of all, of course, the drill itself, as well as a hammer drill, mixer, screwdriver, etc.
Scope of application in everyday life
A hand drill is one of the most necessary things in the everyday life of a home master. With its help, you can easily hang a picture or a shelf on the wall, nail a curtain rod, drive a dowel into a brick or concrete wall, and carry out minor repairs to home furniture. But this is not a complete list of all those household chores that an indispensable assistant will help to cope with.
Extra
1. Before drilling the walls, do not forget to check for hidden incommunications, such as electrical wires or water pipes. You can make your task easier by using a metal detector.
2. Blow out the resulting hole from dust. To do this, you can use a vacuum cleaner or a special dust extractor. An ordinary rubber bulb will help get rid of dust.3. Remember that the diameter of a hole drilled in concrete or brick is always larger than the diameter of the drill used in the job.
