Dry Core Bits - X300 - Masonry

Designed for electricians and plumbers drilling anchor bolt holes and conduit penetrations through cinder block and brick walls, the Diamond Vantage X300 delivers clean cuts in masonry applications. This 1-1/2 inch dry core bit features a .110 wall thickness and 5/8-11 thread attachment, allowing quick mounting to standard angle grinders and core drill rigs. The dry cutting design eliminates water hookup requirements, making it practical for interior work where wet cutting isn't an option. The X300 handles brick, block, and similar masonry materials where you need repeatable hole sizes without chipping or blowout at the exit point. Built for trade contractors running electrical and mechanical rough-ins in commercial and residential construction.
