Are you using the bits that come in the pack of screws?
The first thing I do with them is throw them away.
said by HarryH3:A good hammer drill will solve this problem. (Note that I said "good". The POS ones from Harbor Freight don't have the balls to bust through tough aggregate).
Congrats on passing the test!
My father-in-law brought his Craftsman hammer drill. We are using Tapcon screws and bought a longer Tapcon bit to use. Any recommendations on a better brand?
I know the bits are getting dulled; when one hole was giving me trouble, I figured 'what the heck' and grabbed the unused 3/16" masonry bit that came in a Ryobi bit kit and it instantly made progress over the bit I had been using. Each time I grab a new bit things are easy for a while and then things eventually get slow after a hole or two.
We finished framing the wall making the 'work area' and the wall separating the play area (with the closet). We still have to do the upper/lower/right wall in the 'play area'. The house apparently had french drains that the previous owner had filled. As such, along the outside walls, the concrete there seems far less hard to drill through and certainly isn't as deep. As such, it is my hope that the drilling won't be as hard along the three remaining walls. In any case, I'd still prefer to have the best drill bit possible to make sinking that many screws as easy as possible.
Will gladly take recommendations. We're using 1/4" x 2 3/4" Tapcon concrete screws, so the bit is a 3/16" bit.
