[olug] Drilling Concrete Block-I'm doing it wrong

If I were drilling holes in my basement block I would rent a real rotary hammer.  They are probably ~$30 to rent. 
IMO Expensive drill/hammer drill combo tools are not that good.  I wouldn't want to use a harbor freight hammer drill.
If I had one I would let you borrow it.
YMMV, good luck

Thanks for the info.   This is a "once a year or two" type use case, so the
basic Harbor Freight model looks good for about 20 bucks.
