This bit handles both handheld and rig-mounted drilling setups, making it adaptable for plumbers, electricians, and mechanical contractors running penetrations through foundation walls and floor slabs. Diamond segment construction maintains cutting efficiency through rebar encounters. Built for professional concrete cutters and drilling contractors who need reliable performance on commercial and industrial projects.
