Designed for drilling higher PSI concrete, concrete with medium level of rebar reinforcement, and other hard masonry. #30/40 diamond grit. Diameter: 2-1/2 Inch. 1-1/4"-7 Thread. Drilling depth: 14". Wet use only. With dedicated core drill machines our lab test has shown 40-60% improvement in both speed and lifetime compare to standard wet core bits.
Very glad the item arrived so early as nothing else seems to be arriving as promised. Worked great, had no issues and was able to plan the project in advance.
