Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC installers cutting clean penetrations through cured structural concrete and foundation walls. The X301 Zz Turbo delivers the cutting speed needed when drilling through hard concrete that dulls standard bits. This 5-inch diameter core bit features a .155-inch segment thickness and 1 1/4-7 arbor connection, providing the stability required for precision drilling in dense aggregate mixes. The turbo segment design helps clear slurry and debris from the cut, maintaining consistent drilling speed through reinforced concrete up to 8,000 PSI. Wet cutting recommended for extended segment life and faster penetration rates. Built for concrete cutting contractors and mechanical trades running high-output core rigs on commercial and industrial job sites.
