In power tools, there are several different types of electric saws, including jig saws, saber saws, electric circular saws, band saws, chain saws, etc. These different electric saws are applicable to different scenarios. The working principle of the jig saw is that the motor reduces the speed by the gear, and the eccentric roller sleeve on the big gear drives the reciprocating rod and the saw blade to reciprocate to perform sawing. With different saw blades, metal and wood can be cut. Because the width of the saw blade of the jig saw is narrow , Under different lifting positions, it can realize straight cutting, small curve cutting, middle curve cutting and large curve cutting. Both saber saws and jig saws are reciprocating saws, but the saber saws should be relatively heavy-duty tools, which are different from the jig saw in the hand-held way. They are mainly used for demolition cutting. The cutting accuracy is not as detailed as the jig saw, but it is applicable. The range is wider and the cutting capacity is stronger. Thanks to the compromise between power tool brands, the unified standards have basically been adopted, which means that no matter what brand of machine is purchased, no matter what brand of saw blade is purchased, it has almost achieved universality. Why is it almost the same? Because jig saws are not completely unified for the time being, there are only two types, but there are fewer and fewer ones with round holes in the middle. Most jig saws use the standard without round holes on the left and right sides. . At present, the saber saw basically only has this standard saw blade. Because different working conditions and usage scenarios are involved, it is necessary to choose saw blades of different specifications. This is indeed a headache, because there are indeed more models of saw blades. Taking Bosch as an example, let’s analyze the different scenarios applicable to Bosch’s jig saw blades and saber saw blades. Jig saws can be used to cut different materials, so Bosch’s jig saw blades are distinguished by five colors according to the corresponding different materials. The blue handle is used for sawing metal, such as iron and aluminum plates; the white handle is used for sawing. For cutting wood with metal, such as used templates, which usually have nails inside, you can choose this kind of saw blade; the gray handle is used for sawing various wooden boards; the black handle is used for sawing special materials, such as stainless steel, acrylic, Ceramics, etc.; the red handle is used for sawing various PVC, PA, PS boards, etc. Relatively speaking, jig saws and saber saws are two safer electric saws in use, because the saw blade is reciprocating, in fact, it simulates the movement of manual saws, which is compared with electric circular saws, band saws, and chain saws that work in rotation. It must be safer, so friends who like toss can consider these two types of chainsaws.
