About this product
The CorePlus 91mm Diamond Dry Core Drill Bit is designed for large-scale dry drilling in masonry, concrete and stone. Its 91mm diameter suits substantial work such as large-bore drainage pipes, ventilation systems, electrical service entries and access points for grouped utilities.
The bit uses 8mm diamond segments with a high concentration of premium-grade diamond in the bond, employing advanced diamond/metal bonding for long-lasting core life. A ribbed core body and V-groove segments clear debris quickly, supporting continuous cutting action, while the aerated core design improves cooling and extends operational life.
It features standard 1/2in BSP threading, making it compatible with conventional core drilling machines and accessories.
