Core Bore Drill Bits - Supreme Silver Professional Wet Core Bit

Designed for plumbing contractors drilling clean holes through cured concrete slabs and foundation walls, this wet core bit delivers consistent performance on residential and light commercial jobs. The Supreme Silver Professional series uses a diamond-impregnated segment design that cuts through concrete, block, and brick with minimal vibration when paired with a compatible core drill rig. Wet cutting keeps the bit cool and extends segment life while controlling dust on indoor applications. The steel barrel maintains straight cuts even when drilling at angles or working overhead. Segments are laser-welded to prevent separation under load. Standard arbor connection fits most professional core drilling machines. Built for plumbers, HVAC installers, and electrical contractors who need reliable penetration drilling without calling in specialty crews.
