The hand-held hacksaw is the most popular and inexpensive type of tool that everyone on the farm probably has. There is always something to file in the country or in the garden. But, often there is a need to perform a large amount of work, in an extremely short time, a cordless reciprocating saw is useful in such a case.
The selection of cordless reciprocating saws in hardware stores is so large that it is sometimes difficult to choose a specific model.
Let's try on the basis of technological characteristics of some popular models of tools, namely Makita djr 185z, Makita jr 102dz, Metabo ase 18 ltx695860, Bosh, Bosch keo, Einhell te-ap 18 li, Ryobi one + rrs1801m 3001162, Black decker gkc108, and others, and also figure out which one is better.
This tool is deservedly considered universal, because it is suitable for processing wood, metal and plastic. The cordless saw is used for repairing and installing plumbing in the house, as well as installing roofs. If necessary, the saw is suitable for pruning trees in the garden or cutting wood. If necessary, you can buy different attachments that are suitable for working with glass and ceramics.
Allows to use it in relatively small room, where, as they say, it is difficult to turn around with a more massive instrument. The saw body is long, so you can always find a place to store it. When turned on, only the hacksaw blade moves, so you will not make any hand movements. It is very convenient to cut pipes located in close proximity to the wall.
Some types of cordless saw blades are narrow.
Used for shape cutting on wood and metal. It is easy with them to make a rounded shape of the corners, so as not to cut yourself, to fit the parts in shape for joining.
Various dismantling works with a reciprocating saw are many times faster. For example, if you need to replace windows, plastic or wood, the cordless reciprocating saw will help you to cut the frames and pull out the sashes without any problems.
Before proceeding with the selection of the saw of this type, study all its technical features.
After all, each manufacturer has its own production nuances. First of all, you must understand for what purpose you are going to purchase a product - household or professional.
For use in everyday life, an ordinary inexpensive tool, which is designed for light loads, will fit you. Often these models are sold with consumable kits that can last a long time.
Also, they are accompanied by detailed instructions with a description of what exactly the saws are needed for.
For professional use, of course, you need a unit with more power and functionality.
Experts say that for this tool it is not correct to use the term power. The performance of the saw can be judged by the performance of the battery from which it works. The power of the cordless saber saw for wood depends on the strength of the voltage, and the operating time depends on the capacity, which is measured in ampere-hours.
High values indicate long-term operation without recharging.
The current high-end models are capable of working on a single charge for about 5 hours in a row.
There are models to which you can connect multiple batteries, thus increasing the power of the instrument.
Lithium-ion or lithium-polymer products are considered the best food sources. They are made using special technologies to get rid of the memory effect.
The advantage of this feature is that the battery can be recharged even if it is not completely discharged. Also, they are equipped with protection against overheating and overcharging, which prolongs their life.
Some brands are available on the market , with a stroke rate of up to 3 thousand / min. This is a very good indicator, which is necessary for high productivity jobs. For example, to cut a laminate, take a saw with fine teeth and determine the work at high speeds.
This way of cutting allows you to make an even cut and prevent the formation of jagged edges. Experts advise purchasing a saw with the ability to adjust the speed for various jobs.
The speed control of the saws can be done in two ways. With one of them, it is enough to press the start button of the tool. The more effort you put into pressing, the higher the RPM.
The disadvantages include the inability to maintain a constant work force at the required level.
The second method involves the presence of an adjusting wheel, which is located either at the top of the body or on the saw handle. There are often numbers on the wheel that indicate the speed setting. Before turning on a reciprocating saw with such a device, you must first select the desired speed.
Reciprocating cordless saws for gardening or other work are also equipped with a pendulum stroke - back and forth and up and down with a low slope.
This allows you to extend the life of the tool, as well as remove sawdust from the cutting site. Also, such a move increases the speed of work when comparing such models with those that do not have such a functional feature. It should be noted that the pendulum stroke is not needed if the saw will be used for curly cutting.
Models of battery dust for professional use, equipped with several positions of the pendulum movement, allowing you to work with high performance.
Many models of this tool have a special structural part called a shoe. It resembles the sole of a shoe in appearance. This is a metal piece that attaches to the front of the case. This allows cutting with high precision, adjusting the depth of immersion of the saw into the blade.
The saw in cordless saber models is held by a so-called chuck.
In inexpensive models, the saws are replaced using a hexagon. In more expensive models, I replace the files without any problems using a lever that loosens the fixation. Also, there are models with a key on the case for these purposes. Universal-type chucks, allow the saw to be fixed with the teeth up.
Different models of reciprocating saws, from different manufacturers, have their own additional features in work.
For example, some types are equipped with a charging indicator, which is located on the body of the instrument or on the battery. In front of the saw, there may be LED lighting, which makes it easier to work in a semi-dark room. Also, there are models with a thermal relay that turns off the power at high load.
