How to insert a file in a jigsaw

One of the universal tools is jigsaw. It can work as a hacksaw, grinder, and router, and circular saw. The area of ​​its operation extends to various materials: wood, metal, ceramics, laminate, glass, drywall, tile, plastic, etc. In order for everything to fully function, you need to know how to insert the file into the jigsaw correctly. And for competent and full-fledged work with each of these materials, you need to choose the appropriate file or saw blade.

Power Jigsaw

To work with jigsaw need to stock up a set of files, as for different materials need to use different files.

Jigsaw: features, device and benefits

This tool is a very useful acquisition for a home workshop. He has many functions, with him you will be able to work in various conditions and in almost any position.

Gadget device

The jigsaw device.

Thanks to the achievements of modernity and high technology, jigsaws have ceased to be just a hand tool. After all, the use of an electric or pneumatic drive in his work makes the jigsaw a practically universal household tool. It has also been enhanced by built-in protection, noise and vibration dampers, electronic speed control and touch protection (saw blade).

In a nutshell, you can describe the principle of the jigsaw operation as follows: the torque turns from the engine into a movement, thanks to which the file moves further progressively in the vertical direction.

Electric jigsaw design

Conventionally, the entire device of the instrument can be divided into the following parts:

  • engine block;
  • gearbox;
  • outsole;
  • handle.

If the handle is clamped, the machine will be a closed structure, and you can keep your palm on the handle only from above. The variant with the mushroom-shaped handle can be covered in different ways, as well as calmly change the position of your hand.

You need to follow when choosing a jigsaw, so that the sole and the body are firmly connected to each other, because even the slightest backlash can negatively affect how the tool will work.

Sole jigsaw placed on the surface, which you saw off. Saws (or saw blades) can not be sharpened, they just need to be changed. The tool will not overheat or experience additional overload if you replace the dull file in time.

Jigsaw: 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.

  1. For saw with cross-type shank.
  2. For a saw with a smooth shank.
  3. For a saw with a shank that has a hole.

Jigsaw blades: basic guidelines for choosing and working

Choosing a saw blade for your tool is necessary so that it corresponds to the work you are going to carry out and the tasks you need to perform.

Marking of files

Depending on the purpose and application, the files are marked with different letters and numbers.

First, decide on the materials. Relatively soft, among which rubber, chipboard, fiberboard, wood can be noted, it is necessary to process with high carbon steel blades. The teeth of such a file can also be different: either ground at a free angle, or ground diluted.

To make straight cuts, take a straight file, which will have large teeth. And for any indirect cuts it is better to choose a narrow file (5-7 mm wide).

For cutting laminate you can find special saw blades. They will have small teeth that have a reverse slope.

To work on the metal should choose parts made of tool high-speed steel. Such files go with a curvature in the lower part, made so that the metal does not bully. They are also characterized by the changing geometry of the teeth.

A set of files for wood

A set of files for wood marked with letters HCS.

The steel sheet will cut the tool, which will have an undulating profile and small teeth. To work with non-ferrous metal are the same, only slightly larger. True, they may differ in the shape of the teeth, because may be different (as a wavy cloth or milled divorced).

Files for ceramics require a solid abrasive edge and must be without teeth, while files with medium teeth are suitable for working with plastic, and toothless wave-like with rubber.

Consider the choice and geometry of the canvas. Too short a file can break, jammed in the canvas. Therefore, it is necessary to take such a length that the end of the web extends beyond the cut. The shape of the teeth of the file is also of great importance. Too large teeth can not only deeply cut through the material, but also break the edges of your workpiece.

Metal Files

Metal files are marked with HSS.

Having chosen uniform cloths, you will be able to perform a number of different works. But if you need to do something special, it is better to choose a heterogeneous file. The most popular are bimetallic models with unique qualities. Due to the fact that their teeth are made of solid grades of metal, they can cut both wood and plastic, steel or any other material with great strength. And given the pliability of their carrier strip, you can safely bend such files if necessary without fear of breaking them.

Fixing files

Each master sooner or later faces the problem of replacing the saw blade. This can occur both from their fragility and from the need to perform different types of operations.

Ceramics file

The ceramic file has a continuous abrasive edge, marked with HM.

The easiest way to mount are locks, which are clamped with a key. The best option with such a mount would be an electric jigsaw with one screw on the side. So you can fix the canvas of all thicknesses and even types quite reliably. But there are many models that are widely distributed because of the favorable price, however, the file they pressed against a special block with a slot. This block must be tightened with two screws, which are located frontally. During the installation process, there may be some awkward moments. Even if you managed to insert the file into the jigsaw correctly, but the fasteners you clamped unevenly, the work will be skewed. Still can lock the lock when removing the canvas. It is also possible breakdowns in the thread of the screws or breakage of the front pad due to the impact of the end of the file on the workpiece (during the wrong or uneven fasteners).

The most convenient is the jigsaw, in which the fastening system of the file is quick-clamping. But its disadvantage is that there are certain limitations on the thickness of the clamped webs.

Installing or replacing the saw blade

If we consider the quick-clamping fastening system, we can distinguish several basic steps to replace the file (Fig. 1.).

  1. The jigsaw has a special lever. It is located on the body and frees the file, so you can change the blade without removing the protective cover.
  2. Pull this lever out. So you open the lock and the stock moves forward.
  3. Next, insert the shank of the saw in the jigsaw and release the lever.
  4. Now you will need to adjust the blade fixing plug to complete the installation. To do this, rotate the adjusting screw, gradually achieving the desired position, or tighten it until it stops, and then slightly loosen.

Jigsaw with locking method requires the following steps to install the saw blade.

Installation of a file

Figure 1. The installation process of the saw in the jigsaw.

  1. Open the tool shield.
  2. Turn the lever located on the rod to insert the file.
  3. After you release the lever, easily slide the canvas into the clamp.
  4. Consider that jigsaw with such a lock will take files of limited thickness (according to the size of the slot).

To insert the file into the tool with a screw fastening system, you will need to perform several actions:

  • remove the cover;
  • loosen the screw (usually use hex keys for this);
  • insert the saw blade in the jigsaw (in a special hole near the support roller with the teeth forward);
  • tighten fasteners (clamp evenly with both screws);
  • Replace the cover.

Jigsaw: the nuances that are important to know

In order for your tool to work efficiently and well, and for a long time served, you need to follow simple safety rules and not forget about the recommendations for its operation.

Before you begin work, thoroughly prepare. Depending on what exactly you are going to cut and what should come out of it, choose the appropriate file and set the speed mode of the tool. For precise work, you will need to set a lower stroke frequency than for a quick and rough cut. If in the first case you have to drive the tool as slowly as possible, then in the other - set the maximum speed with the highest degree of paging.

Getting started with a jigsaw

Before you start working with a jigsaw, you need to configure it for a certain type of work, change and fix the file, prepare the support and protection.

In order to avoid problems with chips, take care of a special liner that will serve as a stop (mounted on the sole). Sawing and sawing speed can also play an important role in this issue.

Well understand how to insert the file correctly. Do not pinch it with excessive tension, because it can begin to “play”, which will make the cut line uneven and prevent you from doing quality work. Be careful when replacing, so as not to break the file near the clamps, as often happens.

Thanks to the versatility of this tool, you get a whole set of:

  • manual hacksaw - you can cut and customize the place is not very massive lumber;
  • circular saw - it is possible to slit various materials (plywood, chipboard - even laminated, etc.);
  • reciprocating saw - you can fit mounted lumber near the joints or where it is high, and in other uncomfortable cases;
  • a chain saw - you can safely chop into wood not thick stems or branches, other wood waste;
  • angle grinder - you can chop tin, sheet materials (with a cement base), tile, cut metal blanks (not very massive) and carry out other works;
  • frezer - jigsaw capable of inset not too complex elements, curved cutting, etc.

Practice is needed for any work and for each material, since theory alone is not enough. The key to success will be your patience and unhurriedness, with which you will gain the necessary and useful experience.
