Dry Core Bits - X300 - Masonry

Designed for HVAC installers drilling vent holes through brick and concrete block walls, the Diamond Vantage X300 dry core bit handles masonry applications without water cooling. This 3-inch diameter bit features a .125-inch segment thickness and 5/8-11 thread arbor connection for standard angle grinders and core drill rigs. The dry cutting design eliminates water hookup requirements on job sites where wet drilling isn't practical. Segment configuration provides consistent cutting speed through CMU, brick, and lightweight concrete. Thread mount ensures secure attachment during overhead and vertical drilling operations. Built for masons, electricians, and mechanical contractors running penetrations through masonry structures where dust collection is available.
