An automatic saw or circular saw is simply an indispensable tool during construction and repair work. Wood, laminate, plastic, aluminum … This is not the whole list of materials that can be cut with a circular saw. But in this article, we propose to talk only about how to choose best 8 inch table saw blade for wood for this tool. For some reason, it is this question that baffles many masters.
At first glance, it might seem that it could be easier: go to the store, choose the saw blade that is looking at you, install it in the tool and cut the tree as you like. But this is just a utopia. By choosing the wrong saw blade, you can not only spoil the wood, but also risk damaging the circular and even damage your own health! Therefore, read carefully below for expert advice on how to choose saw blades for wood.
Before choosing saw blades for wood, decide on the goals
The first thing to decide for yourself is for which work you need a blade: cross or rip sawing. In each case, you need to select your own type of saw blades for wood. For the sake of fairness, it’s worth noting that there are so-called universal options. Manufacturers claim that they are equally good at all the tasks that their owners put before them. However, masters with extensive experience still do not advise placing high hopes on such saw blades. If you want your circular saw to last for years and the quality of the effort you expect, go for the clean cut models. That is, separately for the cross cut, separately for the rip sawing. They differ from each other in two parameters:
- the size of the cutting teeth;
- the number of cutting teeth.
The basic rule for choosing a saw blade for wood looks like this: the larger the size of the teeth of the blade, the more confident it goes during ripping, and vice versa, the fewer of them, the better the cross cut.
You may be wondering what happens if you do not adhere to the above rule? Then read:
- If you use a blade with coarse teeth for cross-cutting, you can get a rather sloppy cut. After that, additional processing of the part with hand tools will simply be necessary.
- Using a blade with fine teeth for ripping can compromise the performance of the tool. During operation, such a canvas heats up a lot, and this, you see, is dangerous. In addition, the rip sawing process will be very time consuming.
Now it’s worth saying a few words about the number of teeth. The larger they are, the fewer there will be on the saw blade. Today, the most popular models are 12-120 teeth.
How to choose a circular saw blade for wood based on the parameters?
If you have decided on the type of work for which you need a saw blade for wood, then it’s time to look at:
- Disc type. It can be monolithic or carbide. The first option is made from a solid piece of high speed or high carbon steel. Among their advantages, it is worth noting the low cost, and among the disadvantages – fragility. The teeth become dull pretty quickly, so they periodically have to be bred and sharpened. Carbide wheels are considered to be more reliable. They are made from tool steel with cobalt and tungsten solders. Their cost is slightly higher than that of their carbide counterparts, but they provide a clean and fast cut. And they need to be sharpened much less often.
- Outside diameter. It is limited by the internal dimension of the saw guard and directly affects the cutting depth. To find out which saw blade outer diameter your circular saw model is designed for, read the instructions that came with the tool.
- Inner diameter. Modern saw models are most often designed for the following bore diameters: 16 mm, 20 mm, 22 mm, 30 mm, 32 mm, 50 mm, 65 mm. This parameter is also defined by the manufacturer. When choosing, keep in mind that the disc must sit tightly on the landing pin, otherwise the consequences can be unpredictable.
- Tooth shape. It is worth choosing here based on your goals. The most versatile is a saw blade for wood with variable teeth. It will cope with any type of wood, besides, its cost is quite loyal.
- Teeth inclination. It can be positive or negative. In the first case, the deviation is directed towards the back side of the tooth blade, in the second, on the contrary, away from it.
- Saw blade thickness. The standard thickness is 3.2 mm, but there are other models. Thinner blades are used for accurate cutting of valuable wood species, thicker ones are designed to perform more rough work.
- The presence of slots. Quality saw blades should have special holes with grooves at the ends. This design allows you to reduce noise during sawing, absorb vibration and reduce the heating temperature of the blade. The grooves at the end of the slots have their own purpose – to reduce the risk of blade breakage during sawing.
- Brand. This is one of the most important parameters. The rating of the world’s best saw blade manufacturers includes such brands as Makita, INTERTOOL, Sparta, Matrix. Their quality and durability are undeniable, which is confirmed by a large number of positive responses from users.
