Jigsaw Bosch: types and instructions for use

A jigsaw is a tool that is easy to find in the workshop of almost any person involved in carpentry. Most often, professionals prefer to choose Bosch products, which over the years have proven themselves not only in the manufacturing country, but throughout the world.

The first Bosch jigsaws were born in 1947, and the company still does not give up its positions, and its products are considered one of the best tools on the market. This device is used in order to cut complex contours, as well as create thin cuts. The products present in the assortments are used both in everyday life and for professional purposes. Bosch jigsaws are equipped with a special system that allows you to change the saw yourself without using any third-party tools. This feature distinguishes them from other brands. In addition, it is possible to adjust the sawing parameters by adjusting the pendulum stroke of the saw.

Some models are equipped with a blower system. Joining the vacuum cleaner hose, it allows you to quickly clean the working area from sawdust. It is impossible not to mention the suppression of vibrations, the presence of a roller that makes the cutting movement more precise, the ability to change the angle of inclination and other additional functions inherent in Bosch products. It is worth adding that the company offers both battery devices and jigsaws that are connected to the electrical network.

Electric jigsaw Bosch GST 65B considered one of the most popular models. The power of the device is 400 watts, and the frequency of strokes reaches 3100 times per minute. The device is moderately compact, weighs 2.3 kilograms, which makes the operation process simple and physically not stressful. The jigsaw is equipped with a built-in file compartment, as well as a function for adjusting the angle of the longitudinal inclination of the sole.

Professional device Bosch GST 135BCE is more powerful - this figure reaches 720 watts. It has a speed regulator ranging from 500 to 2800 strokes per minute. Thanks to this function, the craftsman has the opportunity to cut wood plates, the thickness of which corresponds to 135 millimeters, as well as aluminum fragments up to 20 millimeters thick.

Relatively recently appeared model EasyCut 50 with a chain saw with a cutting depth of 50 millimeters. The peculiarity of the tool is that there is no need for pre-drilling. By submerging the saw, the technician is able to immediately create straight, perpendicular cuts. This appliance is electric and is powered from an outlet. However, despite all the advantages, this model cannot be called a full replacement for the jigsaw, since the cutting radius is limited to 10 centimeters.

Model Bosch PST 900 PEL belongs to household tools, but at the same time it has a very powerful motor. The available attachments are capable of handling laminate, composite, steel, plastic and aluminum.The jigsaw does not vibrate during operation and, if necessary, you can quickly change the cutting blade. However, the aluminum outsole often leaves long marks on the material being processed.

Bosch PST 650 is a very budget modelperfect for starting carpentry. The device allows you to process plastic, wood and metal, as well as quickly change the used cutting blade. The device is equipped with a vibration reduction system, and the grip is covered with rubber to reduce hand slip.

Model Bosch PST 670 also recommended for beginners. Its advantages include a powerful engine, comfortable grip design, light weight and metal sole.

Bosch PST 700 Е often chosen for household chores. With this tool, both traditional materials, such as wood and metal, and specific materials such as rubber are cut. The jigsaw is capable of cutting along a curve and even at an angle to the work surface. It is equipped with a protection system that keeps debris out.

Bosch PST 900 PEL Compact has an extensive package, and therefore is used for a wide range of works with different materials. Other advantages include the presence of a backlight, a sawdust cleaning system and an adjustable four-stage pendulum stroke. In addition, the resulting vibrations in this jigsaw are compensated for.

Cordless jigsaw Bosch PST 18 LI is one of the most technologically advanced devices of the company. It is equipped with a special system that allows it to work for a long time without recharging the battery device, as well as an electronic module for speed control. As a result, this model is characterized by high performance.

The saws that come with the Bosch jigsaw, easier to distinguish by shank.

• Gray color indicates the possibility of using for wood processing, blue - metal, and red - polymer materials.
• The white shank allows you to use the saw for both wood and metal.
• Finally, the black shank file is used to work with ceramics, steel, soft and fibrous materials, as well as with a cement base. As a rule, a set of universal files includes all of these options.

Usually, cutting blades are subdivided depending on the purpose, as well as the composition. On the narrow part of the file, you can find information regarding the material used. It can be carbon steel, hardened high speed steel or bimetal, which is a combination of the above two materials. In addition, some high performance files are made from carbide. The presence of a diamond coating on such files allows cutting ceramics and even fiberglass.

For a jigsaw, the manufacturer creates wide blades in order to carry out a straight cut of the material, as well as narrow blades that implement a curvilinear cut. There are coarse-toothed files that can quickly cut thick workpieces, and fine-toothed files for clean and precise processing. Blade lengths typically range from 70 to 250 millimeters, including the shank.

A popular guide rail is the one that allows you to get perfectly straight lines. This device looks like a ruler or rule, equipped with a groove for the sole of an electrical appliance.As a rule, the guide has rubberized strips necessary to prevent the material from slipping, and is secured using clamps. The parallel stop allows you to make cuts parallel to one of the sides of the work surface. This part is very durable, has a long service life and therefore is responsible for the performance of work at a high level. Often, a special ruler is also used to complete the jigsaw.

Among the most popular manufacturers of jigsaws are the trademarks Metabo, Fiolent PM, Interskol, DeWalt, Zubr, etc. However, the Makita brand is usually called the main competitor of Bosch. Which one is better is difficult to determine: both companies produce a wide range of high quality models. However, there are some differences:

• Bosch, unlike a competitor, offers a household product line, which, of course, increases its attractiveness in the consumer market;
• the Bosch brand is ahead of Makita in the speed of new technologies introduction, thanks to the presence of its own high-level research base.

When choosing files for a tool, you will have to focus on the material to be processed, as well as on the width of the workpiece. Depending on the latter, a decision is made regarding the length of the part. For example, a thin sheet of metal or laminate can be cut with a short file, the length of which does not exceed 100 millimeters. Construction timber or metal pipes are processed using saws with the maximum length.

• One of the main rules for operating a jigsaw is that you cannot work with it if the switch is somehow damaged. In this case, you must immediately contact a specialist, without trying to disassemble and repair the equipment yourself.
• By the way, you should not also try to pull out the stuck file with your own hands, it is better to consult a specialist. In a situation where you have to change accessories or replace the file, you must first disconnect the device from the electrical network or turn off the battery. This will prevent the jigsaw from turning on during direct replacement and creating a potentially hazardous situation.
• The cutting blade should always be sharpened and cleaned so that it will not jam and will be easier to operate.
• In general, the jigsaw will have to be well looked after: regularly assess for damage and, if necessary, repair them, as well as check the movement of moving elements.
• Finally, the jigsaw should not fall into the hands of children, as well as people unfamiliar with the principle of operation and who have not read the instructions.
