What it is
The DeWalt DT9559-QZ is a very long SDS-Plus Extreme bit with a diameter of 12 mm and a working length of 950 mm, dedicated to drilling concrete with SDS-Plus rotary hammers. The generous usable depth makes it ideal for through holes in thick masonry and slabs, while the carbide head ensures wear resistance in abrasive materials. The SDS-Plus shank guarantees quick, secure attachment to the tool.
A masonry bit is a carbide-tipped bit for drilling concrete, brick and stone with a hammer drill or rotary hammer.
What it is for
Used for drilling reinforced concrete, in hammer or rotary hammer mode and for drilling solid and hollow masonry, clay brick and blocks.
How to use it
Choose the machine's shank type (straight, SDS-Plus or SDS-Max) and the diameter required by the wall plug. Start the hole at low speed, then engage hammer action, holding the bit square to the surface and without forcing, withdrawing it frequently to clear the dust. Clean the dust out of the hole before inserting the plug.
