What it is
The DeWalt DT20460-QZ EXTREME is a 305 mm diameter diamond blade for general-purpose use. The diamond segmentation is designed to tackle a wide range of building materials, delivering effective cutting performance and good durability even in demanding working conditions.
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 clay bricks and blocks 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.
