Concrete Core Drill Bit - Premium Black Wet Segmented Core Bits

Designed for plumbers and electricians drilling clean penetrations through concrete floors and walls for pipe and conduit runs. These wet segmented core bits feature black-coated diamond segments that require water cooling during operation to prevent overheating and extend cutting life. The segmented design allows for faster material removal and better debris clearance when boring through reinforced concrete, block, and masonry. Standard arbor fitting works with most rotary hammer drills and core drill rigs used on job sites. Water feed keeps the bit cool and controls dust during cutting. Each bit delivers consistent performance across multiple holes without segment loss or wobble. Built for mechanical contractors, electricians, and plumbing professionals running daily installations in commercial and residential construction.
