A diamond blade is a circular blade with diamond segments or rim that cuts concrete, brick, stone, porcelain stoneware and asphalt with angle grinders, floor saws and cut-off saws.
What it is for
Used for controlled demolition, where clean cuts and low vibration are required, for cutting concrete and reinforced concrete and for cutting building materials, from clay brick to concrete.
How to use it
Choose the blade according to the material and the machine and fit it following the direction-of-rotation arrow and the stated maximum speed. Cut without forcing and, when cutting dry, pause and run the blade free to cool it; with wet-cutting models, keep the cooling water running at all times. If the blade stops cutting, dress it on an abrasive material; protect your eyes, hearing and airways.
