The 1" Wet Core Bit with 5/8"-11 Thread is a heavy-duty diamond core bit built for precision wet drilling in concrete, reinforced concrete, masonry, and stone. Designed for use with rig-mounted or handheld core drills, it features a standard 5/8"-11 threaded arbor for wide compatibility across pro-grade drilling systems. The laser-welded diamond segments deliver fast cutting speed and extended bit life, making it ideal for tough jobs like anchor installations, conduit coring, and utility penetrations.
