Core Bore Drill Bits - Supreme Silver Professional Wet Core Bit

Designed for plumbing contractors drilling clean holes through cured concrete slabs and block walls, this wet core bit delivers consistent performance on residential and commercial job sites. The Supreme Silver Professional series features a diamond-impregnated segment design that cuts through standard concrete and reinforced masonry with minimal wandering. Wet drilling keeps the bit cool and extends segment life while controlling dust on occupied sites. The professional-grade construction handles repeated use with standard core drilling rigs, making it suitable for HVAC penetrations, electrical conduit runs, and drain line installations. Built for mechanical contractors and concrete cutters who need reliable core bits that hold up to daily production work.
