SDS-Max hammer drill bit DeWalt DT9429-QZ

What it is

The DeWalt DT9429-QZ is a compact SDS-Max bit with a diameter of 28 mm and a working length of 250 mm. The combination of carbide-tooth head and four-flute body ensures precise penetration in masonry even in shorter holes, while the low weight of around 0.856 kg makes it particularly easy to handle in close-quarters work.

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.
