## Long description

DeWALT DT8931-QZ rotary hammer drill bit with SDS plus shank, 1 cm diameter and 310 mm overall length. The bit has a solid carbide tip with four cutting faces and a four-flute helix designed to reduce vibration, prevent jamming when drilling through rebar, and improve debris evacuation for fast, efficient drilling in hard concrete.
Advantages
The four cutting faces on the carbide tip provide precise cutting and reduce the tendency to walk, while the four-flute helix maximises removal of dust and chips. The SDS plus connection ensures secure mounting in compatible rotary hammers. The design minimises vibration and lowers the risk of the bit becoming stuck in reinforced concrete.
Suitable for
Drilling holes in hard concrete and masonry
Work with rotary hammers that accept SDS plus bits
Situations where drilling through rebar may occur
