This high-performance drill bit features a solid one-piece carbide tip with patented chamfering for low vibration and superior drilling through concrete and reinforcement. Its 4-cutter head with 4 x 90 symmetry prevents jamming on rebar and ensures smooth, even cutting. Reinforced spiral ridges and a high-volume flute design provide excellent dust removal, durability, and reduced wear. The centring tip allows for accurate spot drilling, while the bit easily penetrates steel deck plates like Bondek and concrete in one pass.
