Selection of Diamond Blades & Diamond Segment

How the Diamond Blade Works.


Diamond blades do not really cut, they grind the material through an action of friction with the synthetic diamond bonding matrix. The diamond crystals, often visible at the leading edge and sides of the rim/segment, remove material by scratching out particles of hard, dense materials, or by knocking out larger particles of loosely bonded abrasive material. This process eventually cracks or fractures the diamond particle; breaking it down into smaller pieces. As a result of this phenomenon, a diamond blade for cutting soft, abrasive material must have a hard metal matrix composition to resist this erosion long enough for the exposed diamonds to be properly utilized. Conversely, a blade for cutting a hard, non-abrasive material must have a soft bond to ensure that it will erode and expose the diamonds embedded in the matrix. These simple principles are the foundation of “controlled bond erosion”.

When using a DRY blade, the user must be aware of distinct operating practices to ensure optimum performance. DRY cutting blades require sufficient airflow about the blade to prevent overheating of the steel core. This is best accomplished by shallow, intermittent cuts of the material along with periods of “free-spinning” for several seconds to maximize the cooling process.


During wet cutting operations, liberal amounts of water act as a coolant to sup-port the cutting effectiveness and longevity of the WET blade. Additionally, using water adds to the overall safety of cutting operations by keeping the dust signature down.


Four essentials must be known  about  the  concrete  to  determine  proper  diamond blade selection.:

1. Compressive Strength (hardness of the concrete)

2. Age of the Concrete

3. Aggregates and Sand

4. Steel Reinforcement
