Core Bits For Concrete - X300 - Concrete

Engineered for HVAC installers drilling large-diameter holes through cured concrete walls and floors in commercial buildings. This 6-inch X300 series core bit from Diamond Vantage features a .155-inch segment height with a 1 1/4-7 arbor connection for professional core drilling rigs. The X300 designation indicates this bit is designed specifically for hard concrete applications where standard bits wear too quickly. Segment design provides consistent cutting speed and extended service life when drilling through aggregate-heavy mixes. Suitable for wet drilling operations to control dust and maintain bit temperature during extended cuts. Built for concrete cutting contractors and mechanical trades running high-horsepower core rigs on job sites requiring clean, accurate penetrations.
