What it is
The DeWalt DT8942-QZ is a full-head drill bit from the XLR series with an SDS-Plus shank, designed for very deep holes in concrete with professional rotary hammers. The diameter of 14 mm and the considerable working length of 400 mm make it ideal for through-hole applications and deep, large-diameter anchoring. The carbide head with 4 cutting edges ensures efficient feed, while the reduced-vibration design ensures greater control during prolonged 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.
