    • About Wet Diamond Core Drill Bits

    Often used in construction, plumbing, and HVAC installations, wet diamond core drill bits make short work of cutting through materials like reinforced concrete, hard stone, engineering brick, and natural granite. 

    The rotating barrel of each bit is embedded with industrial diamonds that abrade the surface for fast, efficient drilling. Wet diamond core drill bits are ideal for heavy-duty applications, enabling deep penetration and precise circular holes.

    A continuous water feed cools the diamonds and lubricates the cut - and because there’s no build-up of heat, the drill bits have a long lifespan. Wet drilling also has the advantage of producing no airborne dust, as the water flushes out the debris and turns it into slurry. 

    We offer a wide selection of bit diameters and lengths, so you’re sure to find something to suit the job at hand.
