Dry Core Bits - X300 - Masonry

Designed for electricians and plumbers drilling clean holes through brick, block, and concrete for conduit and pipe runs. This 1-inch dry core bit from Diamond Vantage features a .110 wall thickness and 5/8-11 thread arbor connection for quick mounting on standard angle grinders and core drill rigs. The X300 series cuts masonry materials without water, eliminating slurry mess on interior jobs and reducing setup time on multi-hole projects. The diamond-bonded segment design handles repetitive drilling in CMU block and poured concrete walls up to 6 inches thick. Cuts stay round and true for proper fitting of electrical boxes and mechanical penetrations. Built for trade contractors running daily drilling operations where speed and accuracy matter.
