Premier Diamond P5-WC Wet Diamond Core Drill Bits

Premium wet diamond cores designed for drilling into concrete & reinforced concrete using suitable diamond drilling machines that run at appropriate speeds. The machine speed is mainly dependant on the core size and strength of the concrete. Ideally a drilling rig stand is recommended as this can be fixed down to ensure there is no movement in the set-up. However, for smaller diameters it is possible to use a hand-held diamond drilling machine. A constant flow of water of up to 4 litres per minute is advisable on most reinforced concrete applications, so direct mains water feed is recommended. The P5-WC wet cores can also be used to drill hard natural stones.
