Dry Core Drill Bit - Continuous Rim Core Bit - Concrete

Engineered for electricians and plumbers drilling small-diameter holes through concrete walls and slabs for conduit and pipe runs. This 1/4-inch continuous rim core bit from Diamond Vantage delivers clean cuts in cured concrete without water, making it practical for interior work where wet drilling isn't an option. The .080-inch wall thickness and 10mm arbor connection provide the rigidity needed for accurate hole placement in structural concrete. Continuous rim design reduces chipping at entry and exit points compared to segmented bits. Dry cutting capability means faster setup and no mess to clean up on finished floors. Part number S-00308SDCRCB. Built for electrical contractors, mechanical trades, and maintenance crews running small penetrations through concrete.
