Drill — Useful device in every house. She is a great assistant in such works as:
— twisting screws;
— drilling holes;
— grinding;
— mixing building materials and t.D.
Now you understand what the necessary tool it is. This is where the question arises of how to choose a drill. We will try to figure out this.
What are the types of drills
Types of drills:
— ordinary;
— hammer drill;
— corner;
— screwdriver;
— mixer;
— battery;
— Network.
Now let’s figure out what are the differences in the listed drires.
Ordinary drills — make rotational movements during drilling.
Shock drills (or perforators)-make the movement “back and forth”, except for the rotational movement. This function helps drill materials of high strength. The shock function can be turned on and disabled if you work with fragile materials.
Corner drills — are used for work in places where access is difficult.
Drinks-shuruvrets-such drills are excellent assistants to furniture assembly, since in addition to a standard set of functions, they can be used to tighten screws.
Mixers drills are used to mix building mixtures (cement, paint, etc.P.) and as a regular drill.
Battery drills — are necessary if it is not possible to connect the device to the electric network. They have less power and greater weight, in comparison with conventional drills.
Network drill — the most common type, works when included in the outlet.
Classes of drones
It is customary to divide the drills into two classes: household drills and professional. A professional drill can work about 10 hours a day. Household drills are not able to withstand such a load. It is for this reason that professional drills are made of high -quality materials to prevent premature wear at high loads. It is recommended to use a household drill for no more than four hours and it is necessary to interrupt the work every 15 minutes. However, such a drill also has its virtues:
— affordable price;
— Light weight.
How to choose a drill
At the choice stage, decide the following:
-How much work do you plan to do with this tool?
-Is it planned to carry out work requiring a drill of special functionality?
In addition, take care of the following characteristics of the device:
— power — the greater it is, the faster the work will be done. However, do not forget about the loading of the mains.
— the number of revolutions — the larger it is, the more opportunities the drill provides. Plan to work with nozzles — see that there is more revolutions.
— drilling diameter — do not exceed the diameter specified by the manufacturer.
— What type of cartridge — there are quick -sounding (the drill is fixed with the effort of the hand) and gear cartridges (the drill is fixed with the key). Both types of cartridges have the same quality indicators. Choose what is convenient for you.
Now you know how to choose a drill and what to pay attention to when buying. Buy a tool only in specialized stores and do not chase at a low price, since a high -quality drill cheap cannot be.
