How to choose a drill screwdriver, impact, with a perforator

The main tool of the peasant at all times was a shovel. Among home power tools, the pinnacle of leadership belongs to the drill. Let's talk about the best way to choose a drill for your home.

Using a drill, you can drill holes, make mixtures, tighten nuts. When repairing this tool is indispensable. Hand drills were widely used before. Then came the devices running on mains or battery. It is convenient to work with such a tool; it is compact, lightweight and mobile. The speed and quality are higher than when using the manual version.

Short tips

The market is crowded with various drills. When you go to a specialized store, your eyes run wide, on the shelves there is a tool from domestic and foreign manufacturers in a huge assortment.

Decide on the tasks for which you are acquiring a tool. To hang a frame with a photograph or a bookshelf on the wall is an inexpensive model.

1. Speed ​​control. Required. Not all domestic models have an element. Foreign-made models have a regulator.
2. Boot on the manifold. If it is not present, dust will fall into the housing, which will negatively affect the operation of the engine, the bearings may crumble. The boot is the key to longevity.
3. Punch functionbut. Holes are made with a puncher even in high-quality concrete walls.
4. Powerful cooling system. Protects the tool from overheating, prolongs the service life.
5. Additional functions. Speed ​​regulator, reverse, keyless chuck, hammer drill.
6. Ergonomics, design, weight. The handle should lie well in the hand, and the control keys should be located as conveniently as possible.
7. Nozzles. They are inserted into the cartridge and solve various problems. The “mixer” stirs the paint or putty, the “bit” tightens the screws and screws.

Following the instructions, you will buy a high-quality and reliable tool with various nozzles, which will become your assistant. Dear women, if your men do not have a drill, give it to New Year.

In the article I will tell you how to choose a drill for the house, what types of drilling tools exist, and where it is profitable to purchase them.

Conventional drill

The class of conventional drilling tools goes down in history. The product is called a drill screwdriver - it drills holes and wraps screws.

1. Some models have a force regulator, which is applied to activate the ratchet.
2. Advanced options can change the speed of rotation, depending on the force of pulling the trigger. The cost in most cases does not exceed $ 65.
3. Contrary to the listed functions, I do not advise buying it. Using such a tool to make a hole in a concrete wall is extremely problematic.

Hammer drill

Impact drill has a cartridge in which you can install any drill. The design includes an eccentric that causes the drill to vibrate.

1. Mode switch. The first mode is normal, the second is shock.
2. The cost starts at $ 90.
3. Impact drill - the golden mean between a screwdriver and a puncher. If you have to fight with high-quality concrete, buy a hammer drill.

Hammer drill

The hammer drill is a large, powerful and versatile drill.

1. In addition to a decent weight, the hammer has a high cost. The purchase will cost at least $ 120.Quality models cost from $ 200.
2. A professional hammer drill will even replace a jackhammer. Believe me, you will appreciate it when you have to lay wiring or remove the old wall covering.
3. In the shock model, the eccentric is responsible for the translational movements of the cartridge. In the punch - an electric compressor.

During the selection, be guided not by price, but by the tasks to be solved. You should not save on the purchase of a tool, otherwise you will subsequently have to pay extra for repairs.

Choose a drill / driver

A drill / driver is a common tool that is widely used in construction and everyday life.

Before buying, identify the tasks for which you intend to use it. The parameters and selection criteria depend on the tasks.

1. Battery capacity. The parameter determines the power. The higher the voltage, the greater the mass of the battery. For housework, a 12-volt device is suitable. Otherwise, take the 36-volt model.
2. Rotation frequency. The operating mode depends on the parameter. Slow mode drills large holes; high speed drills for small holes.
3. Torque. The parameter determines the resistance to be overcome.
4. Cartridge. For a home, a cartridge with one clutch is suitable. For more complex tasks, take the product with two couplings.
5. Adjusting clutch. It sets the torque, protects the nozzles from premature failure.

Rechargeable batteries

1. Lithium ion. Expensive. Large capacity, light weight, lack of charge memory, low self-discharge.
2. Nickel metal hydride. Environmentally friendly. They are quickly discharged.
3. Nickel cadmium.The cheapest. They work normally at low temperatures. The discharge of a large current is not terrible.
4. Charger. An old charger charges the battery in 4 hours. Professional options cope in an hour.

The right choice of hammer drill

The main feature of the impact drill is the principle of operation. In addition to rotational movements, the mechanism performs translational strokes. The device drills holes in solid material.

Type of food

Function from a network or the battery.

1. The power drill is lightweight and has increased power.
2. Battery powered hammer drill allows you to work in hard to reach places. Completely eliminates the connection to the mains.

Having decided on the power source, focus on power. The more powerful the drill, the higher the cost. If you intend to use it for home tasks, buy a model with an output of 800 watts.

1. Speed ​​controller Adjustment is carried out by pressing the trigger with different strengths. There are models with a disk regulator.
2. Advanced impact drills are equipped with a processor that automatically selects the rotation speed. The speed depends on the diameter of the drill and the type of material.
3. Reverse. Thanks to this mechanism, the drill can rotate in both directions. The reverse will help to remove the drill when it is stuck in the wall.

Do not buy the most expensive impact drill. Even the most reliable things break down over time.

How to choose a drill with a hammer drill

Hammer drill - a large drill equipped with a percussion mechanism, which forms a blow according to the electropneumatic or electromagnetic principle. The tool is focused on destructive work with solid materials - stone, brick and concrete.

Functionality resembles an electric drill. Many consumers are mistaken, believing that there is no difference between them.

1. Power. The higher, the thicker the wall will break through. The power of the punch without interruption depends on the power.
2. Mode of operation. Single-mode, dual-mode, tri-mode.
3. Single-mode operation. Focused on drilling holes in soft material. In this mode, the punch works on the principle of a conventional drill.
4. Dual-mode operation - hammer drilling.
5. Three-mode operation. Provides for drilling with impact crushing. The rotary hammer operates on the principle of a jackhammer.
6. Rotational speed. The parameter determines the number of movements performed by the drill. For drilling a small hole, high speed is suitable, for a large one - small.
7. Impact strength. The indicator directly depends on the power of the punch. If you intend to use the instrument at home, 3 joules are enough.
8. The weight. The indicator determines the time of work with the tool. Mass directly depends on power.

If you can’t make a choice, I recommend buying a medium-sized rotary hammer. It will help in solving a variety of problems, from drilling to fracture.

A list of the main selection criteria is presented by the frequency of use and the amount of work. An ordinary tool is perfect for a home workshop. A professional home drill may not be required.

If you are engaged in construction, buy only a professional tool. It will last a long time, rarely breaks down and helps to carry out huge volumes of work.
