Dry Core Bits - Star Blue Dry Hole Saw

Drilling anchor holes through cured concrete walls and floors requires a dry core bit that cuts fast without water hookup. The Star Blue Dry Hole Saw from Diamond Products handles these jobs with a segmented diamond rim designed for air-cooled operation. This bit works with standard angle grinders and core drill rigs, making clean holes in concrete, block, and brick without the mess of wet cutting. The blue-coded segments identify the dry-cutting design, so you won't grab the wrong bit when you're setting up. Thread connection provides solid attachment during heavy drilling applications. Works on residential and light commercial projects where running water lines isn't practical or allowed. Built for contractors and installers who need reliable dry drilling performance on concrete and masonry.
