What it is
The DeWalt DT9841-QZ SDS-Plus Extreme 2 drill bit is a professional drilling tool with a 12 mm diameter, an overall length of 200 mm and a working length of 150 mm, suited to deeper holes. The 2-cutter geometry and carbide head ensure effective, consistent penetration in concrete, while the SDS-Plus shank ensures quick engagement and optimal transfer of the hammering action to rotary hammers. The 10-piece multipack is intended for continuous use.
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.
