Core Bits For Concrete - X300 - Concrete

Designed for HVAC installers drilling refrigerant line penetrations through concrete walls and floors, this X300 core bit from Diamond Vantage handles reinforced concrete with a 2-1/2 inch diameter cutting capacity. The .155 wall thickness provides stable drilling performance while the 1 1/4-7 arbor connection fits standard concrete drilling equipment. X300 series bits use segmented diamond technology that stays sharp through multiple holes without requiring frequent bit changes on the job. The construction delivers consistent performance in both wet and dry drilling applications when paired with appropriate core drilling rigs. Built for mechanical contractors, plumbers, and electricians running conduit and utilities through structural concrete.
