About this product
This Irwin masonry drill bit measures 4.5mm in diameter with an 85mm working length, suited to medium fixing applications in brickwork, concrete and breeze block. It is designed to work efficiently with cordless drills, offering faster drilling than competitive bits while retaining durability. The single flute design improves dust removal for increased drilling speed, while the pressed diamond-ground carbide tip provides aggressive cutting action and longer life compared to previous Irwin masonry bits. The body is made from chrome vanadium with high carbon content, allowing greater hardening for a stronger bit with maximum rupture strength.
