Diamond saw blades for cutting metal can cause

1 , diamond saw blade is characterized by soft afraid of hard afraid
2, the metal part of the plastic material , is for marble, glass , the metal to be "soft" is much more
3 , marble, glass is brittle concrete saw blades  material , harder than the metal
4 , diamond is a valuable material , although the diamond saw blade diamond is a man , but it is expensive , it is made ​​by a method using powder metallurgy , that is, the diamond particles in the metal powder mixed sintering rather backward over the blade , the blade is to wrap diamond grinding wheel for metal rubbed off , exposing the diamond particles less than half the pieces , this is the diamond particles exposed head was cut marble "blade"
5 , diamond saw blade "cut" marble , it granite blade   is actually a diamond will powdered marble , marble which will "cut" open to the
6, if using a diamond saw blade to "cut" metal , "soft" diamond particles of the metal will be "glued down " so that the diamond blade failure . Remember: Do not use diamond saw to cut metal !
7 , with ordinary thin grinding wheel cutting metal is possible, although this wheel is a metal ground into powder, but not as good as diamond grit is precious , and that sand is bonded with a special adhesive overall shape , that is, said that the whole can be " cut" of the sand grains , cylindrical sanding off the back of the sand can continue to "cut"
