Diamond Blades

Diamond blades cut much faster and maintain a more consistent cutting depth than Carborundum blades. Diamonds are held in place on the blade by specially formulated metal bonds.

The type of metal bond used on a diamond blade is very important. If you will be cutting a soft, highly abrasive material such as asphalt or "green" concrete, then the diamond blade used should have a hard metal bond. Conversely, if you will be cutting a hard dense material such as "cured" concrete or brick pavers you will need a diamond blade with a soft metal bond.

The harder the material being cut, the softer the "bond" must be; vice versa, the softer the material to be cut, the harder the "bond" must be. There are "wet" and also "dry" diamond blades. "wet" diamond blades require a continuous flow of water upon them for cooling. "Dry" diamond blades may be used dry but should be allowed to cool frequently while cutting.

Another important factor to consider when using a diamond blade is cutting depth. it is very important to cut through the material being cut without running the blade into the substrate underneath. Cutting into the substrate will drastically reduce the life of the blade.
