If in past years with such a tool, we encountered only in sawmills, and now to buy a circular (table) saw. It can be in any hardware store. The article describes in detail the characteristics and find out how to pick up a table saw to their needs.
Almost all saws are powered by mains electricity, but there are rechargeable counterparts.
As for the choice of the manufacturer of this tool is no consensus. As always, good brands like Makita, DWT, Bosch, Hitachi. Close to him approaching manufacturers such as Sparky, Sturm, Zenith.
How to choose a table saw
The table saw blade is designed for quick and easy cutting of almost any soft material. This wood and materials based on it, as well as plastic and soft metal.
With regards to wood as the most popular material in the construction, I can say that such a cut as the tool it is possible across and along the grain. Also standard on all models tsirkulyarok it is possible to perform cuts at an angle of 45 degrees.
Structurally, the tool consists of an electric motor with the shaft, the table saw blade with teeth guard and some additional elements, which we discuss below.
Home or Professional?
When choosing a table saw, first of all, you need to understand yourself, why do you need this tool. If you have a lot of construction work – sawn timber, flooring, laminate, chipboard or OSB, then turned his attention to professional models. If the tool is needed on the farm only in rare cases, but most of the time he is in your pantry without cause, it makes sense to buy household table saw.
What is the difference between domestic and professional tool?
The main difference is the engine performance of its resources, as well as the quality of used parts and materials.
Engine power consumer less power table saw, professional tools. Accordingly, less power is used at a smaller diameter disc, which cuts the material to a lesser depth.
In addition, household tools engine off periodically, giving it time to cool. Let me explain by example.
Using a professional model, I have one and a half hours of continuous operation was able to saw a number of blanks chipboard, which was enough for me to create four large cabinets. If used household model, the work would have taken 2 times longer. The quality would remain the same. But the cost will be higher professional tool twice.
Manual or desktop?
Selecting a particular embodiment depends, of course, up to you. Where do you work?
Let’s say you have equipped a special place in the workshop in the country or in the garage, and all work will be carried out there. In this case, choose a table table saw.
Manual or desktop disc table saw?
Table models are usually more power. Also on this stationary machine it is very convenient to operate.
By the way, on sale there are special devices that enable secure portable table saw on the table upside down. The result is a mini-machine, which can operate with greater convenience. However, such fixing is not suitable for all models.
There are also models of table saws that have already included the setting of the base. Consider these characteristics when choosing.
More powerful engines are able to quickly cut the material, and the density of the material may be higher. The process of cutting will be much easier. Have you ever sawed wood, on which there are bitches? So, low-power saw could easily jam in one of the knots.
As they say, the direct dependence of the power and performance.
On the other hand, low-power table saws have the “weighty” advantage – it’s low weight, thanks to which the tool can be carried around without much straining. Thus, the model 2000 watt weighs about 7 kg, and saw with 1200 W power only 3-4 kg.
For domestic work is quite suitable power tool 1000-1200 watts. If you are not running a professional tool, the power reserve will remain unclaimed.
From power depends on the price of the entire product. This is logical. The difference in price can be up to one hundred percent or more.
The frequency of rotation of the saw blade
This indicator shows the effectiveness of the blade work. Disk rotating at a higher speed, capable of more effectively cut hardwood. Higher turnover – less chance of jamming the disc in the wood. In addition, the slice is a more accurate and smooth.
Incidentally, the speed can be high even on low-power disk saws, so choose a model with the greatest possible speed drive.
What determines the depth of the cut? Of course, the diameter of disc used. Consequently, the size of the unit must be increased depending on the size of the working disc and this of course leads to weight gain.
Depending on what kind of material you cut, select the depth to which the saw blade can dive. Lightweight models used for household work, have a dive depth of 40-45 mm. This depth is sufficient for cutting chipboard, plywood, fiberboard, dyuymovok-boards.
If you intend to cut thicker material, choose a table saw with a cutting depth of 50-55 mm. It is the size of the chassis, which selects the most people for summer jobs.
The depth of 60-70 mm longer needed for professional work, such as the beam. Of course, such a drive can effectively spin the engine is powerful enough.
There are also table saws large size and weight, which are able to cut the material to a depth of 140 mm. Such devices are used on an industrial scale, so for them we will not stop.
Cordless Saw – tool allows you to work autonomously, although at different performance. Rotational speed in the storage disk saws is of less importance than in the electric table saw.
These models successfully cope with the timber having a small thickness and low density. Battery charge is enough for 30-50 minutes of work, after which the battery has to be charged again.
It delivers certain inconveniences, because the battery charge can last up to 4 hours.
The ability to work at an angle
The design of most models allows the cut at an angle of 45 degrees. However, there are models that can cut even at an angle of 60 degrees. Typically, the cutting angle can be adjusted with only one hand, since the other side is located on the engine. Although there are varieties of saws with cutting angle adjustment on both sides. For example, such a convenience is available Makita MLS100 model.
Some useful constructive additions:
Function sawdust collection.
Basically, all the models have connections for connecting a vacuum cleaner or vacuum connections. This ensures that no chips and dust during the operation, especially indoors.
A very useful addition to allowing the incision to perform more accurately. Interestingly, on the index operation does not affect the flying sawdust, as the laser beam falls on top of a layer of sawdust.
The body of most units is made of durable plastic. It is quite robust material used for the production of power. In some cases, you can find a metal enclosure. Devices with a metal housing have a greater weight. Therefore, if you are interested portability, choose a plastic housing.
Lock accidental launch.
In order to ensure safe operation on the tool body has a button, thus avoiding accidental activation saws. Ask the seller if there is such protection on the model you like. Sometimes the absence of such a key can result in serious injury, so do not neglect this advice.
Some saws have given a supplement that allows you to start the cut workpiece from the very beginning, and to a certain place. This may be useful, for example, when it is necessary to cut a hole in the solid plate.
This feature allows you to extend the motor life and make work safer.
Ease of disc replacement.
As a general rule, continuous operation with a table saw sawing sometimes have to change discs. Some discs are designed to work with wood, while others – for cutting metal. Ease of replacement is sometimes very important. It is very inconvenient to change the disc with a simultaneous operation of two keys. Therefore, this change also note.
