ALL OF OUR KNOTCHED RIM DIAMOND SAW BLADES ARE STEEL CORE.
|
The blades will rust if left standing in water for an extended period of time. If you choose to leave your diamond saw blade in water over night we recommend adding a rust inhibitor to your water.
Both style diamond saw blade coarse and fine start with a die struck steel blank. The blanks, as many as 200 side by side are mounted and clamped on a perfectly true shaft. After mounting narrow slits are cut along the outer edge of the blade blanks, from 4mm to 9mm deep depending on the size and style blade.
After the blanks have the notches cut into them, they are placed one at a time in a machine, diamond powder is placed into all of the notches, the machine closes and the notches are forced closed over the diamonds. Resulting in what is called a notched rim diamond saw blade.
With the diamond filling the notches in the diamond saw blade, if the blade seems to slow down in cutting, you can take an old corundum grinding wheel 100 or 80 grit, slice into this a few times, and you once again have a clean smooth cutting blade. With many other style diamond saw blades, it is pointless to try to sharpen the edge, because only the edge and side had diamonds plated to them.
