SDS-Max hammer drill bit DeWalt DT9438-QZ

What it is

The DeWalt DT9438-QZ is an SDS-Max rotary hammer drill bit with a diameter of 35 mm and a working length of 450 mm. The carbide-tooth head and four-flute geometry (4 cutting edges) ensure decisive drilling in masonry with tidy dust extraction; the weight of around 1.899 kg provides stability when working large diameters.

An SDS-Max bit is a carbide-tipped bit for rotary hammers with an SDS-Max chuck, for large-diameter, deep holes in concrete and masonry.

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

Clean and lightly grease the shank, insert it into the chuck until it locks and select hammer drilling. Drill with the hammer held in line with the hole, letting the machine's weight do the work without pushing, and withdraw the bit frequently to clear the dust. If you hit a reinforcing bar, stop and move the hole; do not cool a hot bit in water.
