Diamond Core Drill Bit - Star Blue Segmented Wet Core Bits

Plumbers and electricians running conduit through cured concrete walls rely on wet core bits like these to create clean penetrations without cracking the surrounding material. The Star Blue segmented design allows water to flow through during drilling, keeping the bit cool and flushing out debris for faster cutting and longer tool life. These diamond core bits handle reinforced concrete, block, and masonry with consistent performance across residential and light commercial applications. The segmented pattern reduces friction and provides aggressive material removal while maintaining straight, accurate holes. Built for tradesmen who need reliable core drilling performance on job sites where dry cutting isn't an option.
