Laser level – a device for plotting horizontally or vertically in the form of lines or dots using LEDs. Laser levels are used on construction sites, in landscape design, as well as for the repair of apartments and houses. Easy control, affordable price and compact size make laser levels affordable for everyone. Using the laser level, you can quickly and easily paste wallpapers, lay tiles, hang a picture or a shelf. It is enough to turn on the device, press the button and direct the beam to the surface – a straight line or perpendicular is ready, you can start work.

The choice of models on the market is wide, from the cheapest Chinese options to professional laser levels. In a large number of characteristics it is easy to get confused, but everyone can find and buy the best laser level suitable for the work performed.

How To Use Laser Levels

What to look for when choosing a level?

• Type of device – a static laser level is able to cope with most tasks when repairing an apartment or a house, you can choose a universal device that can project both lines and points. The rotation level is of high cost and is used only by professionals at large construction sites.
• Manufacturer – to achieve high accuracy results, you should choose a tool with good optics, a reliable body and high-quality diodes. Companies such as Leica, Spectra Precision can guarantee the high quality and reliability of the equipment supplied.
• Operating range – for working in a room, as a rule, a working distance of VM is enough, for working on a construction site it is worth choosing a beam range of more than 20 meters, and professional devices, for example, of a rotary type, can spread the beam to a distance of 300 or more meters.
• The accuracy of the device – the error of budget models of unknown brands can be high, but the equipment of popular brands can provide accuracy of up to 5-1 mm at a distance of tens of meters. The most accurate are the laser levels of the rotary type. To ensure projection accuracy, it is necessary to periodically check the laser level.
• Self-leveling system – when choosing a device, we advise you to pay attention to the laser level self-leveling, this greatly simplifies the work making it fast and accurate.
• The number and direction of the rays – the simplest and cheapest models of the laser level can project one or two beams, this is enough to perform simple tasks, but to solve more complex ones, you should buy a laser level with a turn of the degrees of the rays, the price of such a device is higher, but apart from building the horizontal and vertically, it can direct the beam to the right, left, and also project points. A large number of beams allows several specialists to do the work simultaneously, for example, laying tiles on opposite walls.
• Options – a device, a set of batteries or a battery, instructions are included in the standard package, sometimes a case for storage is included in the standard package, but often it has to be purchased separately. In professional devices, the kit may include a target and special glasses, as well as radiation detectors, these devices allow you to work over long distances.
• Type of fastening – to repair a house, it is enough to buy a laser level, which can be used by placing the device on the floor. But to work outdoors, you need a tripod for the laser level, which can be bundled with the device or must be purchased separately, given the size of the thread.
• Price – the cost of the laser level can vary dozens of times, but everyone knows that if you buy the cheapest laser level, you should not expect the same result from it as from a high-quality device

The drill is designed to drill holes in various surfaces. What other functions can it perform and what to consider when buying, read in our short guide for choosing this power tool.

Professional or household?
Depending on how often you intend to use the drill, you can understand which model you need: professional or household. If you plan to work with the tool every day, and even for several hours, choose from a number of professional ones; otherwise, it will quickly fail. If you need a drill from time to time, opt for household models: they are equipped with a less powerful engine, however, unlike professional ones, they have wider functionality and are cheaper.

Drill type

The hammerless drill has the functions of drilling and screwing-unscrewing fasteners. The absence of a percussion mechanism allows you to make holes of high accuracy, provides a compact size and light weight of the device, however, due to this, such a drill can only be used with materials of low strength.

The hammer drill is equipped with a hammer mechanism. This means that in addition to rotational, the drill head also performs translational movements back and forth. Such a function increases the torque of the device, which guarantees the possibility of drilling even very hard materials: concrete, brick, natural and artificial stone. Such a drill can also be used as a screwdriver.

A drill / driver is designed for screwing and unscrewing screws and self-tapping screws, but, unlike a simple screwdriver, it is equipped with a drilling function. This device is an indispensable assistant in the assembly of furniture. The drill mixer mixes various construction solutions, glue, paint. Suitable for drilling, but not hard surfaces. Such drills have high power and torque, but there is no shock function.

The best cordless drills may not have constant power and maximum torque from a wired electric drill powered by AC, but for most DIY applications they are much more convenient and powerful enough. During the blocking, they sold very well, so if Britain has more shelves, now that the worst of it will end.

Modern cordless drills offer more features than ever, thanks in large part to the advent of a lithium-ion battery. Lithium-ion batteries are not only lighter than older nickel-cadmium (Ni-Cd) batteries – they significantly save weight on the wrist and forearm – they also hold a charge when not in use, and do not mind charging them half empty .

The key factor is the voltag. Simply put, the higher the battery voltage, the more power and torque you will have to drill through durable materials such as steel, especially concrete and brick.

As an added bonus, all cordless drills serve two purposes: drilling and screwdriving. Combined drills are slightly different in that they also include impact for heavy masonry. If you live in an apartment with plasterboard walls, most likely you do not need this extra power.

Most instructors in this review will do the basic things themselves, but it goes without saying that you get what you pay for. More expensive models are invariably better built and add more energy to your elbow.
