Designed for HVAC installers cutting through post-tensioned concrete in high-rise construction, this turbo-segmented core bit handles the demanding work of drilling clean holes in hard aggregate mixes. The X301 Zz Turbo features a 4-1/2 inch diameter with .155 wall thickness and 1 1/4-7 arbor connection, providing the rigidity needed for straight cuts through reinforced slabs. Turbo segments deliver faster cutting speed and improved dust removal compared to standard segmented designs. The Diamond Vantage manufacturing ensures consistent diamond exposure throughout the bit's life. Wet drilling recommended for maximum performance and bit longevity. Built for mechanical contractors, plumbers, and electricians running conduit and pipe penetrations through structural concrete in commercial and industrial settings.
