Concrete saw
From Wikipedia, the free encyclopedia
A concrete saw (often known as a consaw or road saw) is a power tool used for cutting concrete, masonry, brick, asphalt and other solid materials. Concrete saws are powered by petrol, hydraulic, pneumatic or electrical motors. The significant friction generated in 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.
