How to choose an electric jigsaw?

Jigsaw-is a special carpenter's tool, often used during the repair work, the manufacture of furniture and other wooden products. It allows you to cut the sheet material, and in contrast to the circular saw, jig saw can perform not only direct but also curved cuts. This tool can also be used for the manufacture of various decorative items made of wood, plastic, plexiglass, ceramic tiles and other materials.

In this article we consider the features of the electric jigsaws and main technical parameters, which are very important to know if you are going to buy this tool.

The design of the electric jigsaw

All electrical jig saws have a very similar structure, this tool generally consists of these elements:

robust housing with a comfortable grip;
baseplate (foot);
electric motor;
reducer;
nail file.

Opportunities tool depend on the characteristics of these parts, and the presence of other design elements.

Housing

The material of the shell tool should be durable and capable of high temperature blows.

It is also very important body shape and comfortable handle. The handle must sit securely in the hand, very good, if there is a special coating to an electric jigsaw does not slide in the hand. It is considered to be the most comfortable handle skobovidnoy form that allows good control of the tool position. Mushroom shape jigsaw when gear is positioned vertically and the handle perpendicularly with respect to it, less reliable, since such tools difficult to control.

High-quality jigsaw should have special holes for ventilation housing. The fact that it is heated in the process of work, and the possibility of cooling increases the lifetime of the device. It is important that the body was well protected from the ingress of dust and moisture.

Soles

This is an important design element that provides a support tool during operation. It is of several types:

Pressed steel-the easiest, but it has a weak resistance to scratches and other mechanical damage;
pressed steel with an additional reinforcement frame made of cast aluminum-due to the special frame they are more robust and reliable;
cast steel with steel plate-the most durable, well keep their shape, are able to withstand even a drop.

Some models have jigsaws soles can be inserted into the table thanks to a special thread and screws directly into the sole. This expands the range of use of the tool.

The saw blade

For each material used own nail file, which has a unique shape of the teeth. In addition, they are made from different types of steel, and may have an additional coating, which increases the rigidity of the sawing surface.

Jig also have a different type of attachment:

Keyword 1 or 2 bolts-the name already clear that the installation jig saw in sawing occurs by means of special fastening elements, which are fixed by tightening one or two screws. It is very important that the bolts are tightened firmly and securely. Otherwise, nail file can quickly become loose, which will greatly interfere with work or result in damage to the saw blade.
Quick-system-this option is more practical and convenient. This Jig saw blade can fix in a matter of seconds, you do not need a personal twist. Please note that there are special fabric with a special liner.

What technical specifications should look at when selecting jigsaw

To choose the right tool, you need to consider with which materials you want to work on this will depend on the main technical parameters of the jigsaw. It is important to pick up the device so that it is easy to cope with the load, provides an efficient cutting and can maintain long-term work.

Power

This is one of the main parameters that directly affect the speed of the cut, as well as the thickness of the material, which can run the tool. Power jigsaws are divided into:

household-their power is in the range of 350-500 W, they are suitable for working with particle board and plastic;
semi-they are 500-800 watts, they are easy to sawing wood, plasterboard, ceramics, plexiglass, metal and other construction materials;
professional-800-1300 watts and above can work with almost any material, including metal and steel.

It is important to understand that the more powerful device, so it is harder and dimensions, and work harder with him.

The speed and stroke adjustment of the bar

The higher the frequency of stroke sawing, the smoother will be cut. However, we must remember the features of some materials such as metal and ceramics are very high speed is not recommended. This is due to the fact that steel is very dense and at high speed will be very warm, and ceramic tile is quite fragile and can break crack at high speed.

Therefore, when choosing a jigsaw look not only at the maximum speed, but also the possibility of its adjustment. This will make the tool more versatile and durable, because the saw blade will not break due to the increased loads. speed considered optimal in the range of 2500 to 3200 turn/min. For household use the device can be chosen, even at a lower speed, but then the quality and cleanliness of the cut may suffer.

The thickness of the cutting material

The maximum thickness which is able to saw jigsaw is determined by two factors: the engine power and the hardness of the material. Choose a model taking into account what material planning work and thick sheets.

Type of food

Electric jig on the type of food can be divided into 2 groups:

Network-have a power cord and connect to a conventional household outlet. They do not depend on the battery capacity and often the more powerful model.
Battery-quite a popular option, their advantage in autonomy, since they are not attached to the network. But there are drawbacks-short time working, as is often the battery is low. It is always best to have a spare battery on hand.

Additional features

A good jigsaw may have some additional set of features that not only make its use comfortable and efficient, but also make it possible to expand the scope of use of the tool. Several features make the tool easier to use, some are expanding the range of tasks. Each brand is trying to equip their products special features, here are just a few examples:

Pendulum stroke. Typically, sawing moves only in the vertical plane, up and down. Availability of the pendulum action provides motion also horizontally. This reduces wear on the teeth fabric and prolongs tool life. Often it provides an opportunity to change the amplitude of movement or total shutdown of the horizontal movement. Please note that the use of the pendulum action is not suitable for all materials. In qualitative models has 4 positions for different materials: wood of medium hardness, sawmills, soft wood, plastic and metal
Adjust the foot of the slope. Platform angle can be adjusted simply turning the unit case, or with a special key. The presence of such an option expands the range of tasks that can be implemented using a jigsaw.
Connection for chip removal or blowing. This is very convenient, because in the process of accumulating a lot of chips, and stop work in order to remove all not always desirable, because the process is slowed down and reduced quality. Some models also have the ability to connect a vacuum cleaner, which also increases the efficiency of removal of debris from the work surface.
Highlighting. The presence of a flashlight that illuminates the work surface to make use of the jigsaw more comfortable for those who often work in low light conditions. increase comfort when working in low light conditions. This will contribute to a more clean cut, as you will be very nice to see the work surface.
Laser. A laser pointer is usually installed in front of the jigsaw, it can be accurately adhere to the predetermined direction, performing a rectilinear cutting material. Laser-this is a great indicator that acts as an alternative to conventional linear layout. However, in profile cutting, it is useless.
Anti-vibration system and silencer. These features will help to make the working conditions with the tool as comfortable as possible. Vibration will not stop, and it will be easier to hold the tool.
Shield. It provides additional protection shelf web from foreign objects, cord, etc. Also this screen will not scatter the chips, it is especially important when working with metal.
Smooth start. The availability of this function protects the device from a sharp rise in motor load, and the masters-the jerk instrument at the time of starting the tool. When the motor is to gain momentum gradually, very slowly.

Properly selected jigsaw-the key to a good result. The tool has worked long and hard to cope with the problem, when buying is recommended to consider a few points.

For simple household tasks (sawing a small wooden or plastic workpieces, ceramic tile, laminate, etc.) will be enough of 500-700 watt device. When you purchase a more powerful model, you most this simply overpay for the extra wool, as much of a difference in the work do not feel.

The powerful device is recommended for small workshops, where a large amount of work and jigsaws to work continuously for several hours almost non-stop. Note, however, that the more powerful the machine, the more he needs time to cool down. If you have to work very actively and for a long time, be sure to specify the duty cycle particular model.
