Diamond Core Drill Bit - Star Blue Segmented Wet Core Bits

Plumbers and electricians drilling through cured concrete for pipe and conduit runs depend on wet core bits like these to power through without burning up the diamond segments. The Star Blue segmented design allows water to flow through while cutting, keeping the bit cool and flushing out slurry for faster drilling and longer tool life. Segmented cores cut cleaner holes in reinforced concrete compared to continuous rim bits, with less binding when you hit rebar. These wet bits require a water source during operation—either a dedicated core rig with built-in water feed or a helper with a hose. Diamond Products manufactures these bits for professional concrete cutting applications where dry drilling isn't an option. Built for mechanical contractors and concrete cutters running wet coring equipment on commercial and industrial job sites.
