SDS-Max hammer drill bit DeWalt DT9445-QZ

What it is

The DeWalt DT9445-QZ is an SDS-Max bit with a diameter of 40 mm and a working length of 450 mm, dedicated to large-section holes in masonry. The carbide-tooth head and four-flute geometry ensure decisive penetration and efficient dust extraction; the weight of around 2.36 kg provides the stability required by 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.
