About this product
This Irwin masonry drill bit measures 20mm in diameter and 160mm in length, suited to heavy duty drilling in brickwork, concrete and breeze block, particularly for substantial fixings with cordless drills. It is claimed to drill up to 60% faster than competitive bits while retaining durability. A single flute design aids faster dust removal for increased drilling speed, while the pressed diamond-ground carbide tip gives an aggressive cutting action and is said to last 20% longer than previous Irwin masonry bits. The body is made from chrome vanadium with high carbon content, allowing greater hardening and strength for demanding trade use.
