Dry Core Bits - Star Blue Dry Hole Saw

Designed for electricians and plumbers drilling clean holes through cured concrete and masonry walls for conduit and pipe runs. The Star Blue Dry Hole Saw from Diamond Products operates without water, making it practical for interior work where wet cutting creates cleanup problems. The dry core bit design uses industrial diamond segments bonded to a steel barrel, delivering consistent cutting performance in concrete block, brick, and poured concrete. This configuration reduces dust compared to standard percussion drilling while maintaining straight, round penetrations. The system works with standard rotary drills, eliminating the need for specialized coring rigs on smaller jobs. Built for electrical contractors, plumbing crews, and HVAC installers who need reliable dry drilling performance on residential and light commercial projects.
