A better understanding about how blade works

One day one of my friend gave me a call, her told me that she saw a machine in the market, then she heard the comments from several buyers said that the blade can cut everything. When she heard it could cut everything, she gave me a call. Then I went to saw this blades, it is amazing that the only thing what can cut everything, a small blade how to cut everything, I don't believe this. I saw some sharp blades but it can't make it to cut everything, So I come to google and search it to understand what exactly to make of the dual saw blade and why it can cut almost everything. Development and production of the two-wheeled different special blade is the Momo Mr. Hauff who is the world saw system father use himself blade technology and world's most advanced production equipment in the industry, the perfect combination of crystal. Not only long working life but also a wide range of cutting , using the same blade can also easily cut steel, aluminum, copper, wood, plastic, cable, glass curtain wall, automobile glass etc. This saw blade is made from Tung-carbide metal matrix structure of the cutting head when the realization of the cold hard metal cutting saw that is different from the ordinary without teeth grinding wheel piece, ordinary non-tooth saw is the high-speed grinding wheel by friction discharge of high temperature melts the metal and welding it. So there will be a lot of spark generation, cutting surface is not only flash but also produces high temperature will burn or scratch the operator, different wheel saw cut can be easy to complete this work. However, using AGICO dual saw can resolve all the above problems: The blade has three advantages: a, cutting speed, high efficiency; b, cut surface finish is particularly high, no flash; c, is the real cold cutting. The unique blade technologies allow our users to cut through nearly any material precisely and powerfully: Each blade has the counter facing sawteeth, so one side cuts while the other one smoothes when the dualsaw is under working condition. In this way, it will not cause any splinters or the breakings. Two-ways blade is coated with solid lubricant, the coating with the world's most advanced surface coating process and materials, not only reduce a large extent between the two saw blades and saw blade and cutting material between the friction, but also increasing the blade of the heat resistance, wear resistance and corrosion resistance, which can greatly reduce the extent and the two saw blades and cutting material between the friction between the blade and increase the heat resistance, wear resistance and corrosion resistance. The DualSaw patented counter rotating blade technology makes it the only saw with 2 blades that simultaneously rotate in opposite directions: forward, backward, top and bottom! Unlike other saws, this professional grade saw's unique technology and dual blade design allows users to cut through virtually any material without changing blades and lets you plunge cut without the usual pilot hole drilling.
