Drilled 4 today. Brand new concrete bit. Went well for about an inch. Then it was tough. Does a hammer drill make much difference? I have more to do, Thanks

Big Difference with a hammer drill -bigger the unit the better and faster the drill works .

A rotary hammer drill and SDS bit will be a night and day difference. If you have a lot of holes to drill renting a rotary hammer drill and purchasing a bit is the way to go. SDS bits are a bit expensive compared to standard carbide, with a lot of holes to drill they are a bargain.

Creek rock and rebar get in the way- take a punch when it stops and try to break the rock- we use Makita battery powered drills and sds bits , they hold up well - and get used hard at work

What size holes are you drilling? Hammer drill and SDS Bits are the only way to go . Like others have said bigger is better. Rentals can pay for themselves quickly.

Years ago I had almost 60 holes to drill in 2 commercial bathrooms-tile and cement. I started getting 12 holes drilled but wasted 4 bits-masonry in a hammer drill. I said screw it and went straight to Hilti-bought a new SDS drill and their bits! They have a 2 carbide tip where most others are a one carbide tip. Just used one bit on all the rest!
