I need to drill 12 holes, each sized 3/4" diameter, and each 6 deep. I'm drilling into some well cured 4000 psi concrete.
I have a 1/3 horsepower hammer drill, and a quality 3/4" masonary bit.
Am I asking for trouble? I.E. should I go ahead and rent an industrial rotatory hammer drill?
And should I drill some smaller holes first, and progress up to my final 3/4" diameter? Or is it best to drill the 3/4" hole from the start?
