as the title states, will a regular drill drill into concrete? I have a big gear reduction drill that will twist your arm off before it stalls out, but i dont know if it will cut it or not... any input is appreciated, thank you.

Sure. It's not very efficient and the bits won't last as long but in a pinch it works.

It will be a slow process and you'll burn up drills in a hurry, but it will make holes.

Should be no problem. I run a construction Co. & sometimes don't feel like getting out certain tools if i'm in a hurry. Drilled tons of holes with just a dewalt cordless and never had a problem. After about 1/2" dia. holes I'd opt for the hammer drill just for speed.

OK cool, sounds like ill be alright. my situation is I need to narrow up the current garage door opening (which has no door as of current) at my g/f's house, it is currently about 15' wide and only 6'6" tall. so i am gonna narrow it up a bit, and put in a man door on one end. but i was unsure how to fasten the board to the concrete to frame it in. i guess concrete anchors are my best bet.

something that worked for me, was a center punch and time. drill as far as you can with the standared drill, pull it out drop your center punch into the hole and start bashing it with a hammer, after a few hits with the hammer and center punch, drop in the drill again till your not makeing any progress, then switch back to the center punch. takes time but works and doesn't completely trash your drill bit.

..wouldn't do this for more than 4-5 holes before I'd borrow a hammer drill.

try to go slow and use the hammerdrill bit and you can use tapcons they are thick blue colored concret screws that should be fine

I used a 5/8" air drill and 1/2" bit for about 15 anchor holes, it needed to be sharpened after that. Out of curiosity, why not buy a .22 powered concrete nail gun and go that route? I just got the el cheapo you hit with a hammer, works fine for me, think it was $30.

You can do it in a bind...but if you know you are gonna be doing it you can usually go rent a little bosch bulldog hammer drill for half a day for $12 or so...you'll have to buy a bit but you would have to do that anyway

Just be sure to have a license for it if the OSHA inspectors show up.

It takes all of 5 minutes online to take the tests. :)

low tech but i needed to drill a few holes for my bender stand, and ive got this 3/8" craftsman drill i was tring to kill (still can't) i used a 1/2 crete bit and literally just put the drill on high and started stabbing the drill into the hole basically simulating a hammer drill... It actually did better than i thought it would.. Still havn't killed the drill...

Same here. I had to drill four 3/4" holes about 5" deep to mount my air compressor and the best thing I found was a little Bosch 14.4V cordless 3/8" drill. On the low speed setting with lots of downward force it bored out those holes fast! And the drill is still going strong. I'm a huge Bosch power tools fan.

Why not use liquid nails or some other strong ass glue and just a few tapcons to anchir your sil plates?

OSHA can't do shit to him since he is a private indvidual doing this for himself. :D the rental place may require a certifaction though.

Remember if this is for a foundation that you have to use an approved anchor.

I bought a HF SDS hammer drill with drills on sale with a coupon for under$40.

I use my air impact gun and one of those drill adapters to 1/2"

Works well
