Is a hammer drill needed for them to drill into concrete???????
No, but sure would make the job easier. Use a variable speed drill and go slow.
Then perhaps a better quality brand of drill bit would be a better ideal.
No, but it will take a LOT longer without one. I've only done 1/4" holes without a hammer drill, and only 1" deep or so for plastic anchors. Depending on the concrete and how many years it's been curing, it can be a one minute job, or a five minute job. Drilling without a hammer drill also requires tremoundous pressure on the bit. If you were closer, I'd be happy to lend you a roto hammer and a whole range of bits from 3/16 to 7/8. Or, if you have a crapload of holes to do, I'll ship it to you to use, as long as you promise to give it back...
What if you just have to drill through a half inch of stucco? Can you use a regular variable speed drill?
I'm sure I could use one of my father in laws. I am going to replace the post on my front porch and I want to secure the post brackets to the concrete with some 4" concrete screws. I have had the stuff to do it for over a month now and I feel like getting started on this little project. The three post that are there now are ugly and I want them out. Besides I'm sick of not doing anything around the house........
IF it is a post screws wont work that great, tapcons are good but have low strenght.
get some 3/8 lags and lead shealds way stronger (1/2" hole), or use a sleave or wedge anchor I would say 3/8th but 2 1/2" long very strong.
tapcons or any concrete screew are very prone to snapping when tightening or just stripping to the concrete.
if you even had to you could rent a drill for pitance.
remember to drill deaper then the anchor leangth.
This is true very focking true. On to plan B.
Stud/wedge anchors are the best, IMO.
I'll check them out.........
you can use a regular drill bit(that you don't care about) to drill through stucco. Its just a very thin coating of mortar on top of Styrofoam and chicken wire.
Use a Ramset and concrete nails. Quicker, and those nails are strong little buggers.
Slow speed will kill the bits. I wouldn't go so slow as the bit is just barely turning. Keep a moderate speed. Slow speed dull any bits very quickly.
Be careful not to use wedge anchors too close to the edge of the concrete or when tightening it could break out (spall) the edge of the concrete and make things look like Sh1t. If you don't want to worry about breaking the concrete or messing with anchors use Simpson Strong Tie SET Epoxy available at the HOme Depot or Lowes. Not too cheap but the abosolute best way and by far the strongest. Just trust me on this. I know this application and product very well. You could also rent the drill and bits from the HD rental store they useally have on site too.
the ramset nails are strong but there holding power is really not the great, you can pull them out fairly easly.
ataching the bottom of a post would make it a big lever and pull them out.
Plus it often blows out the concrete it is is week
Other than LN, JB Weld are both the poor mans choice to fixing things to hold for good.
Not on my house. It's a thick wire mesh and literally a half inch of cement/masonry.
Ok, this is Corey's thread, when I'm ready to drill I'll post up...
I use my 12v Makita to do small holes in concrete but when I have to do any holes through foundation I bust out the old D Handle. With an 18" 3/8" bit I can go through about 16"s of poured foundation in about 45 seconds. Of course I put all my weight on it and end up blowing big holes that I have to fix all the time :doh:
don't buy cheap bits and you should be fine with any drill. the last job i did that required one was a laugh. my friends was junk,it was sunday so he had to go to the local hardware.we had to drill 60 holes through cinderblock.it took 11 bits. home owner quality ****.
