Dry Core Bits - X300 - Masonry

Drilling anchor holes through cured brick walls and concrete block requires a dry core bit that can handle masonry without a water feed. The X300 from Diamond Vantage delivers a 3-1/2 inch diameter cut with a .125-inch segment thickness and 5/8-11 threaded arbor connection that fits standard angle grinders and handheld core drills. The dry cutting design eliminates water hookup requirements on interior jobs where wet cutting creates cleanup problems or damages surrounding materials. This bit handles brick, block, and poured concrete applications where you need clean holes for HVAC penetrations, electrical conduit, or structural anchoring. Built for masons, electricians, and concrete contractors running quick drilling jobs without water access.
