When choosing a sawing machine, check the maximum cutting power it can do. On the packaging of a saw, the machine has usually listed the thickness and type of objects that can be cut by the machine. The frequency of blade movements or SPM (strokes per minute) and the length of the pull or length of stroke are also generally included in the form of numbers on the product packaging. Then, the wider the cut, the bigger the size of the saw. You can read this to know more.
Now, by knowing the ability of a saw machine, you can certainly choose a product that suits your needs, right? It will be more profitable if the product can be replaced by the blade. The cutting power of a saw machine is also determined by the blade. To reduce costs, some people buy chainsaws at affordable prices, then replace their blades with higher quality products. The result, cutting machine power is qualified, but the price remains within budget.
