Circular saws, pendulum saws and chain models are the best known and most used, especially in small carpentry workshops and for household tasks. But there are many other options about which it is good to know something, if you are making renovation plans or you want to start producing furniture or various ornamental objects.
If you want to buy an electric saw, it is good to know that there are more options available than you might expect. It is true that some of them are specialized, designed for workshops and commercial operations, and less suitable for home, but it does not hurt to know what options you have before choosing.
It is a version designed especially for workshops working with wood, but it is also used for chipboard, MDF, plastic and even some less hard metal variants, such as aluminum. The cutting disc, provided with sharp teeth, is integrated in the top of a workbench and connected to a motor that spins it at high speed.
Sections easily in straight lines, being very useful when you have to shorten planks or cut into two large chipboards. However, it requires a larger work surface for installation and is a fixed version, which you cannot transport too easily, if you need to work elsewhere.
It is also among the saw models that have associated one of the highest accident rates, so be careful how you use it and carefully follow all safety rules.
The circular model
A circular saw, on the other hand, is exactly what you need if you have arranged a small space, where you like to work on all kinds of wood or plywood projects. It also uses a blade in the form of a disc, but this time we are talking about a mobile version, which is held in the hand and moves on the sectioning path, this time the material being kept fixed.
These versions are easy to use and transport, do not take up much space, but require additional guidance if you want to get a precision cut. They are suitable for sectioning on medium and large lengths, in a straight line or slightly curved.
Circular variants with miter
Recommended for carpentry and furniture workshops, the miter-type models include a vertical blade support structure, which allows the cutting disc to be lowered from top to bottom, on the material, with greater precision than in the case of circular versions. standard.
They can be used to cut wood, plastic, chipboard and other materials of low and medium hardness and to create indentations on their surface. It is one of the most adaptable power tools you can buy, being suitable for home use.
Saw for metal and ceramics
These models look very similar to those with a miter, the most important difference between the two being the type of disc used for cutting. While the miter circular uses a sharp-edged steel blade, the metal and ceramic one uses an abrasive disc that advances more easily and finely through hard materials, without damaging the edges or causing cracking.
It is a model that you also need if you want to cut hard elements such as concrete, brick or tiles or faience.
If you are interested in electric saw models ( here we have compared some models ) it is good to know that the most popular and most used are probably the models with chain and rail. Usually used to cut trees or cut logs to form firewood, these devices are used without a fulcrum, their entire weight being supported by the user.
They are available in wired versions, stronger, but conditioned by the proximity of a power source, and respectively, variants with rechargeable battery, slightly weaker, but with better mobility.
For cleaning trees from dry or diseased branches, cutting through wood, brick or pieces of faience or tiles, but especially for demolition and renovation of the house, you need a reciprocating saw.
Unlike most other types of saws, these versions cut through repeated back and forth movements, the blade hitting the material to pass through it. Because it can be cut both vertically and horizontally, such a tool is very useful when you have to prepare OSB boards, cut PVC pipes or install windows or doors.
Pendulum format for detail sections
Another model frequently used in DYI type works is the pendular one. As a design, it is quite similar to each other, but the support sole is larger and the direction of movement of the blade is lengthwise, from top to bottom, and not forward.
These versions are available in cable and battery versions, respectively, in small formats, easy to handle and store. They are part of the category of models with manual support, so the saw is moved on the sectioning path, and the material stays in place, well fixed.
A pendulum saw is exactly what you need if you work frequently with projects that involve making fine cuts, in tight curves or sharp angles, with small broken lines. It can also be used to cut a piece, of any shape, from a larger board of wood or chipboard or MDF.
Because ceramic tiles (sandstone, faience), stone, granite, glass or porcelain are difficult to cut correctly with an ordinary saw, there are models designed especially for this type of material, hard and brittle. They generally use diamond discs, which give them both the strength and fineness needed to section these types of structures.
There are two variants of devices in this category. Some work with dry ceramics, others with wet alternative, the latter having the advantage of preventing excessive heating of the work surface due to friction.
