Sawing concrete requires a concrete saw (often known as a consaw or road saw.) Is a power tool used for cutting concrete, masonary, brick, asphalt and other solid materials. Concrete saws are powered by either gas, hydraulic, pneumatic or electrical motors.
The very significant friction generated when cutting hard substances like concrete means that the blades need to be cooled to prolong their life and reduce dust.
Blades are either abrasive or diamond tipped.
