Blade Selection

This depends a lot on the type of concrete that you are cutting; whether it is General Purpose, Cured Concrete, or Reinforced Cured Concrete (know the reinforcement, e.g. wire mesh, and rebar), the hardness of the concrete, and the Type of Saw that you are planning to use!

The segments of a diamond blade are made up of a mixture of diamonds and various metal powders! The bond that holds the diamonds together comes in various forms! There is a HARD BOND which is recommended for cutting SOFT AGGREGATE, MORE ABRASIVE AGGREGATES. Then there is the MEDIUM BOND! This bond is most commonly used; diamond blades with a medium bond are preferred for cutting MEDIUM TO MEDIUM HARD AGGREGATE! Lastly, there is the SOFT BOND which is recommended for cutting HARD TO VERY HARD AGGREGATE!

RULE OF THUMB:

Amount of Steel Rebar Reinforcing

Heavy steel reinforced concrete tends to cause diamond blades to cut slower while on the other hand, lightly reinforced concrete tends to allow the diamond blade to cut faster. The following guideline provides examples of various types of reinforcing.

Rebar gauges are measured in eighths of an inch -#4 rebar is 1/2" diameter, #5 is 5/8", etc.
