Wet / 45° tapered top segment / For cured concrete core drilling

Professional Roof Top Core Drill Segments for Easy Starting on Cured Concrete
Starting a core drill on the hard surface of cured concrete can create high initial cutting resistance and make stable drilling more difficult.
DIATOP Roof Top Segments are designed with a 45° tapered top profile to support easier starting on cured concrete.
The tapered segment shape helps reduce cutting resistance during the initial stage of drilling.
Multiple segment sizes are available for core bit diameters from 2 inches up to 16 inches.
