What it is
The DeWalt DT9552-QZ is a hammer drill bit from the SDS-Plus Extreme series with a diameter of 12 mm, dedicated to drilling concrete. It features a carbide-tooth head and two-cutting-edge geometry, while the reinforced core supports its strength under stress; the SDS-Plus shank allows direct coupling with compatible rotary hammers. With a working length of 110 mm, it is a versatile choice for medium-depth holes in the sturdier diameters.
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.
