What it is
The DeWalt DT40260-QZ diamond disc from the Extreme Runtime range is a professional cutting accessory with a 22.23 mm mounting bore, supplied individually in a pack of 1 piece. Its diamond construction is designed to ensure effective, smooth cuts on building materials, with performance designed to withstand intensive use.
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 cutting concrete and reinforced concrete, for cutting building materials, from clay brick to concrete and for straight and shaped cuts in tiles and porcelain stoneware.
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.
