Diamond Core Drill Bit - Star Blue Segmented Wet Core Bits

Designed for plumbers and electricians drilling clean penetrations through cured concrete walls and floors, these Star Blue segmented wet core bits deliver consistent performance on residential and commercial jobsites. The segmented design provides efficient cutting action while water cooling extends bit life and controls dust during operation. Diamond Products engineers these bits with industrial-grade diamond segments that maintain cutting speed through reinforced concrete, block, and masonry. The wet cutting method keeps the bit temperature down and prevents material cracking around the hole perimeter. Each bit threads onto standard core drill rigs for quick changeovers between hole sizes. Built for mechanical contractors, concrete drillers, and installation crews running multiple penetrations per day.
