What is a reciprocating saw
Outwardly, this device is a long tool with a pistol grip, at the end of which there is a working blade. There is a trigger and several switches on the body. In fact, the design of the device is simple, and any person can deal with its work.
In fact, this is an ordinary electric jigsaw, and its principle of operation is exactly the same as that of a jigsaw. Although the latter is a descendant of an electric saw, because it was produced 20-25 years later. It turns out that the blade makes a reciprocating motion, thereby choosing the material to be cut by the teeth. When the tool was improved, that is, they began to use a pendulum stroke in it, it became a revolutionary invention, because the cutting efficiency of the reciprocating saw was greatly increased. This characteristic will be discussed separately.

Selection criteria
A good reciprocating saw should meet the following parameters:
- be powerful and productive;
- have the optimal weight for you (the more it is, the less the saw's maneuverability);
- provide easy blade replacement;
- have a quick braking function;
- have an acceptable cost and a warranty period of 1 year;
- belong to a well-known brand, which is distinguished by the high quality and reliability of the manufactured equipment.
The owners' feedback on the reciprocating saw is also extremely important. Before making a purchase and choosing a reciprocating saw, we recommend reading reviews on the Internet, watching video reviews.
It is also worth studying materials from the farming forums and the tool forum, as well as familiarizing yourself with the comparative characteristics of the top models of various brands.

It will not hurt the future owners of the equipment to collect more complete information about electric hacks. To do this, it is advisable to chat with real people on the forums, find out from them which, in their opinion, reciprocating saw works well and which one does not, watch video reviews, read reviews. All these actions will help the buyer to form his own objective opinion about the offered product and to decide on the choice of the tool.
Features of cordless and cordless reciprocating saws
Electric saws are divided into two types - mains powered (mains) and autonomous (battery). Both of these types have their pros and cons at work.
Power and cutting depth
In matters of power, its "barreck" counterpart is ahead of the network tool. Yes, this is understandable, cordless electric saws are used where mobility is needed, which means low weight and, accordingly, more modest power.
Mobile versions are used in the field, where active work is required from them, but for a limited period of time
The power of such models can be from 0.5 to 0.6 kW. Most network models are designed for a consumption of 0.9-1.2 kW.
An indicator such as the cutting depth directly depends on the power
In addition, the length of the web is taken into account, which on average is 200 mm. The density of the material to be cut also plays a role.
Maximum frequency of movement of the reciprocating saw blade
This parameter is one of the key ones. The higher the frequency of movement of the saw blade, the harder the surface it will be able to cut. This matters if you are buying a saw for cutting metal or stone. This parameter is also called the stroke frequency. It is measured in revolutions, which, in fact, is equal to the number of reciprocating movements. Average rates are from 2.5 to 3 thousand revolutions per minute.
Pendulum stroke
The special design of the gearbox, due to which, when the blade moves backward, it deviates slightly from the cutting line. That allows you to reduce the heating of the tool and effectively get rid of debris and sawdust during work. This feature is not used on all models.
Power supply type
When choosing a model, one should proceed from the peculiarities of the work and its volume. If you need a powerful enough tool, then you shouldn't even consider the battery model.
And, conversely, if you are looking for a tool for one-time work, especially on the road (cutting branches or disassembling a structure), then in this case the priority is convenience and mobility.
There are pros and cons in both forms, but here it is worth choosing the lesser of two evils. In each case, this choice is purely individual.
Quick-clamping saw blade
The most convenient electric saws are with a quick-clamping system. In this case, the blade can be changed without removing the gloves. In some variations, the chuck allows the blade to be mounted upside down. There are many variations of use.There are models - with a large backlash (margin for saws), there are suitable specifically for a particular model.
Quick-release locks have only one drawback - the limitation on the thickness of the clamped blades
Most blades come with a universal mount, but some manufacturers are promoting their shank and chuck shapes.
The weight
Weight is an extremely important moment for a hand tool. There are professional models of reciprocating saws that weigh up to 8 kg. Household models on average do not reach two.
