Jigsaw Interskol: sawing curvature correction
It is worth paying attention to the domestic production of the Interskol jigsaw. It is produced in Izhevsk. For household use, this is a perfectly acceptable option.
It has many positive qualities, and the most impressive is its low cost. But there are also disadvantages

Replacing the quick-release saw blade mount
This is the curvature of the cut. What is the problem and can you get rid of it? The fault was the quick-release fastening of the file. The fact is that it is designed for the maximum saw blade thickness. All thinner cutting tools in the mount just dangle.
How to get out of this situation? It is necessary to replace the quick-release mount with a simple device with ordinary bolts. It is not difficult to make it. You need to take a square rod, cut off two blanks, drill holes in them and connect with two M5 bolts with nuts. The procedure for attaching the saw blade will be somewhat more complicated, but the tool will produce a smooth cut.
Refinement of the jigsaw design
In addition, you can modify the very design of the tool and limit the movement of the file in the transverse plane.
For this you need:
- take sheet aluminum and cut the plate to the size of the jigsaw sole;
- in the front part of the workpiece, it is necessary to make a cutout according to the size of the working area of the cutting tool. File all edges, make bevels on the inner longitudinal edges of the cutout;
- from plexiglass, you need to cut a plate to the size of the working area of the saw blade. File all sharp edges and make reverse bevels on the outer longitudinal edges;
- the aluminum plate must be marked for its installation on the sole of the jigsaw. Drill holes and chamfer for the installation of countersunk head screws;
- a piece of plexiglass must be inserted into an aluminum plate, after having made a cut at the place of its position.
The saw blade will now be limited in lateral movement almost in the cutting zone during operation, which will give it even more straightness.
How to choose the right file and how to insert it into a jigsaw
Home comfort May 22, 2018
A jigsaw in the household is an irreplaceable thing. Modern models of jigsaws can cut not only wood.
They can also handle plastic and aluminum and even ceramics. But for each material, you should purchase your own files.
How to choose the right file for the material, and how to insert the file into the jigsaw, will be discussed in this material.
General in files
Regardless of the clamping system of the jigsaw itself, all files have the same standard slots for the holder. Therefore, there is no need to look for files for a particular jigsaw model. They all fit perfectly with any model. But how to insert a file into a jigsaw, this will already depend on how the mount itself on the power tool is designed.
The difference in files
Looking at the window, you can see that some files have large teeth, others have smaller ones. This is what suggests that each file has its own material. You can understand that a file with large teeth is more suitable for soft wood, while cutting metal blanks will be able to be done only with a file with small teeth.
The files differ in the materials from which they are made and in length.A more detailed classification of them will be given below.
Classification of files for jigsaws
Sometimes specialists make cuts in different materials with some files. We will be guided by the advice of experienced experts and explain why it is best to use this or that file, based on their recommendations.
- T101D - large teeth, so the cut will be rough, but the fastest. Perfect for regular wood (beams, boards). Cope with both chipboard and plywood.
- Т101В - the teeth are smaller, and therefore the edges of the puncture will be kept clean. Suitable for plywood and plexiglass.
- Т101BR - the letter "R" at the end means reverse. So the teeth are located in the opposite direction, although the file itself is the same. It is best to cut glued wood, laminate with such files.
- T119VO - due to the thin cross-section of the file, it can be used to perform very accurate figured cutting on materials such as fiberboard or chipboard, keeping their edges as clean as possible.
- T118A - small teeth and high-strength steel of such files allows them to make cuts in metal blanks and plastic.
- Т224D - excellent for cutting / sawing aluminum blanks.
Features of fasteners in jigsaws
Now that we have figured out a little with the choice and purpose of the files, we will figure out how to correctly insert the file into the jigsaw. To begin with, each company is constantly striving to improve fastenings on the tool, making them more comfortable and simpler, and not at the expense of reliability.
Manufacturers rightly believe that the less hassle the tool will deliver during the maintenance process, the more opportunities that they will purchase exactly it. But, meanwhile, there are still early models, whose file attachments are far from perfect.
We will analyze the types of travel mounts and how to insert the file into the jigsaw, based on each mount, in more detail.
Bolt Clamp (Shoe)
This is less and less common today. The saw shank is inserted into the slot of the clamp and the bolts are tightened. In the process, the saw is adjusted, otherwise some misalignment may occur, and the cut will be far from ideal. The advantage of such clamps is that any kind of files with any shank configuration are suitable for such jigsaws.
Sometimes there are fasteners with only one bolt. For example, some models of the German company Protool are equipped with such mounts. How to insert a file into a German jigsaw, and then how to adjust it? Everything is done simply. The saw shank is inserted into the slot in the clamp and the bolt is screwed in. No special settings are needed here.
Radial clamp
This is one of the types of quick-release fasteners. This is often equipped with jigsaws of the German company Stayer.
How to insert a file into a jigsaw with a clamping mechanism of this configuration? It's simple.
Scroll to the side of the clamp head, insert the file with the shank into the slot of the clamp until it stops, release the head. To anyone who does not understand anything or is too lazy to read, you can watch the following video.
So, as can be seen from the above, there is nothing difficult either in choosing consumables or in replacing files. By and large - we press the key, the old file jumps out, in its place we insert a new one into the slot, release the key. All is ready. You can work.
Jigsaw: features, device and advantages
This tool is a very useful purchase for the home workshop. It has many functions, you can work with it in various conditions and in almost any position.
Jigsaw device.
Thanks to the achievements of modern times and high technologies, the jigsaw is no longer just a hand tool. After all, the use of an electric or pneumatic drive in its work makes the jigsaw almost a universal household tool.It has also been improved with built-in protections, noise and vibration dampers, electronic speed control and touch protection (saw blade).
In a nutshell, the principle of the jigsaw can be described as follows: from the engine, the torque turns into movement, thanks to which the saw moves further progressively in the vertical direction.
Jigsaw design
Conventionally, the entire device of the tool can be divided into the following parts:
- engine body;
- reducer;
- sole;
- handle.
File application table.
If the handle is clamped, then the machine will be a closed structure, and you can keep your palm on the handle exclusively from above. You can cover the mushroom handle option in different ways, as well as calmly change the position of your hand.
It is necessary to ensure that the sole and the body are firmly connected to each other. even the slightest backlash can negatively affect how the tool will perform.
The sole of the jigsaw is placed on the surface that you are sawing off. Saw blades (or saw blades) cannot be sharpened, they just need to be changed. The tool will not overheat or experience additional overload if you replace a dull file in time.
Jigsaws: main types
By purpose and design, they are all the same. But there are several types of tools, depending on how the file is attached to the jigsaw.
- For saws with a cross-type shank.
- For saw with smooth shank type.
- For a saw with a shank that has a hole.
Varieties of jigsaws
Before proceeding to the direct specifics describing the process of installing the file, it is worth clarifying the types of tools affected. Since the jigsaw device has quite a few incarnations, we inform in advance that in this manual we will touch on 3 of its varieties: manual, electric and stationary. A band saw, which is also sometimes called a jigsaw, will not appear in this article. Now a few words about each type of device under consideration. Hand jigsaw The cheapest version of the tool for making figured sawing of wood and its derivatives. When using special blades, it can be used for cutting thin metal. The speed of work and the quality of the cut depends entirely on the experience and physical data of the employee. Quite easy to use and does not require many hours of study. Electric Jigsaw A more advanced and expensive type of tool for making straight, cross, oblique and curved cuts. Depending on the saw blades installed, it can work with wood, plastic, metal and even ceramics. Has a high frequency of the saw, due to which the quality and accuracy of the cut is usually reduced. Sometimes an electric jigsaw is justly called manual, since it must be held during use. This tool is considered one of the most popular in everyday life, second only in popularity to a screwdriver and a drill. Stationary jigsaw is a very convenient and functional machine for amateur and professional work. It is widely used in industry and in everyday life. Works with thin saws, like a hand jigsaw, but in cutting speed it is not inferior to an electric one. The main advantage of using a stationary jigsaw is complete freedom of both hands, which allows you to more accurately control the position of the workpiece during processing. The device copes well with straight cutting, but first of all, it is intended for curly. Having finished with a brief description of the devices, you can move on to the main question of the article. Let's look at how to insert a blade into a jigsaw and what nuances should be taken into account when doing this. Let's start with the electrical models.
Fastening jigsaw files
The scheme of fastening the saw to the jigsaw.
The accuracy of the device and its performance directly depend on the features that were listed above. But there are other points that affect how convenient it is. During the use of the jigsaw, you will have to face the replacement of the saw blade. This is not associated with the performance of work of different types, in which the canvases must also be used differently. The most common type of shank is European, or, as it is called in another way, “Boshevsky”. It has a cross configuration. Such files are sold in absolutely any store that sells tools, this is their feature.
As a rule, there are two main ways of attaching the file, it can be:
- frontally secured to the jigsaw;
- quick-clamp to fix in the jigsaw.
In many cheap models of jigsaws, the block, which is tightened with screws (there are two of them), clamps the blade with a cut. These screws are frontally positioned. Such a system has high compatibility, but otherwise loses. For example, fasteners that are not clamped evenly can cause skewing. In this case, additional wedging should be performed. The impact of the saw on the workpiece with the butt end can lead to the front block breaking in half or the screw threads to break off - this occurs when the tool is carelessly handled.
Quick-clamping blade fastening
There are a lot of ways to do this. The only significant difference from “regular cartridges” is that versatility is not present. Only files with the same shank are suitable, and there is also a backlash. Most often, this does not play a big role, since there are a huge number of canvases. Fasten the file between the jigsaw's axes. And the backlash, in turn, will not affect the operation of the jigsaw in any way, usually it has a longitudinal shape. The only drawback of quick-release locks is that the thickness of the sheets that need to be clamped has a limitation.
It is very easy to insert the file. The jigsaw, which has a narrow blade, is capable of making rather complex bends. But for this, it is necessary to turn the entire tool in the direction of sawing or the board itself, with which you will have to work. It is good when a scroller is present in the jigsaw - a special device for turning the saw directly during operation without affecting the position of the tool.
Classification of jigsaw files according to the type of material being processed
For wood and wood materials
The jigsaw was originally designed to work exclusively with wood. Modern tools have learned to saw both metal and plastic, but their main purpose is still cutting wood and its derivatives. That is why most of the saw blade assortment is designed to work with these materials. "Wooden" files are divided into groups according to the type of work for which they are intended.
Fast cut.
When carrying out some types of work with wood, it is often not the accuracy that is important, but the speed of the process. Saw blades for fast cutting of wood are capable of providing high performance. They are easy to recognize by the following characteristic features:
- long blade (from 60 mm),
- large teeth (up to 6 mm),
- large amount of divorce (about 1 mm).
Clean cut.
Operations such as cutting furniture boards from chipboard or trimming parquet boards require a smooth and accurate cut. When solving such problems, where the quality of work comes to the fore, and not productivity, blades for a clean cut are used, having:
- average size of teeth (no more than 3 mm),
- minor divorce.
Most saws have their teeth pointing towards the jigsaw. So that the front side of the material after cutting the chipboard or laminate is as accurate as possible, without chips and scoring, the workpiece is placed with the back side to itself / the tool. To cut from the "face", you need to use a blade with a reverse tooth.True, working this way is more difficult than usual - you have to overcome the pushing force of the tool.
Figured cut.
It is almost impossible to cut a curve with a small radius with an ordinary wide blade. For a figured cut, specialized files are used, which, due to their size, easily pass rounded sections:
- narrow canvas (no more than 4 mm),
- fine teeth (up to 2 mm),
- small length (up to 40 mm),
- beveled back.
For metal
I must admit that a jigsaw is not very suitable for cutting metal: the tool can hardly cope with the load, the process is very slow, the files quickly become blunt. However, sometimes this extreme method is justified.
Saws for metal differ from saws for wood: they are made of extra strong steel and have fine (up to 1 mm) teeth, set in a wave-like manner. If you often use a jigsaw and at the same time perform a wide variety of work with it, we recommend keeping at hand three metal blades at once - separately for aluminum, other non-ferrous metals and steel. If you have to cut metal only from time to time, it will be enough to have only a file for steel - it will certainly cope with cutting non-ferrous metal products.
For polymer materials
For cutting pipes and other PVC products, large-toothed blades designed for cutting wood or metal are suitable.
Fine-toothed files will also cope with the task, but you will have to cut at the minimum speed, otherwise the plastic sawdust softened from the high temperature will clog the teeth of the file. For thin sheets of plastic and plexiglass, fine-toothed metal blades are excellent. To cut thick plastic, you can take a file on wood and cut at low speeds.
For specific tasks
Files for glass and ceramics are made of extra strong alloys and have diamond or tungsten carbide spraying on their cutting edges. It makes sense to use a jigsaw to cut ceramic tiles or glass only if you need to cut curly elements; there are other, more suitable tools for cutting these materials directly.
Drywall and other building materials containing abrasive particles of gypsum, cement or sand will quickly blunt any files. An exception is the carbide-tipped saw blades specially designed for these materials.
A file designed for cutting cardboard, rubber and other soft materials is more like a knife. It is "toothless", and its cutting edge is made in the form of ground waves.
Universal
Universal saws, made, as a rule, of high-speed steel, are used to work with various materials - wood, plastic, metal. You should not expect a high cut quality when using them.
The lineup
The Japanese brand Makita offers its customers a huge selection of all kinds of jigsaw models, each of which is of high quality and reliability.
Let's consider the most popular options.
