Dry Core Bits - X300 - Masonry

Designed for electricians and plumbers drilling anchor holes and conduit penetrations through brick, block, and concrete walls. This 2-1/2 inch dry core bit features a .125-inch segment height and 5/8-11 thread arbor connection for quick attachment to standard angle grinders and core drill rigs. The X300 series cuts through masonry materials without water, eliminating cleanup and allowing immediate work in finished spaces. Diamond segments are engineered for extended life in abrasive block and brick applications where wet cutting isn't practical. The dry cutting design makes this bit suitable for interior work, renovation projects, and locations where water access is limited. Built for trade contractors who need clean, fast penetrations in masonry without the mess of wet cutting systems.
