Drilling into concrete slab
Posted on 5/18/20 at 10:21 pm
Posted on 5/18/20 at 10:21 pm
I'm trying to anchor a gazebo into the slab on the back porch. Gazebo weighs about 800 pounds. The kit provided me with 2" concrete anchor screws. I've gone through 4 3/16" concrete bits with my Milwaukee 18v hammer drill and have gotten 1 1/2 holes drilled and nearly burned up my drill. Any idea of a better way to do this? At $8 a drill bit and needing to drill 16 holes in beginning to wonder if it's even worth it to anchor it.

Bosch Bulldog SDS+ hammer drill is what you need, you'll never drill masonry with your 18V drill again.

Rent a hammer drill and the bit that comes with them is what you need

Do you actually have it set to hammer and rotating the correct direction? I had a bobo arse ryobi 12v hammer drill that would be done with that in no time flat. 2 inches isn't a deep enough hole to wreck that many bits so quickly. Was legit shocked at some of the tapcon holes I could drill without going out to the trailer and getting the SDS.

I do have it set correctly yes

I'd go the rental route for the bit and tool with Phillips self-drilling anchors.
Rental stores used to carry the anchors, if not,HD or Lowes carries them.

Maybe the hammer part is not working correctly. Or, could you possibly be trying to drill through a piece of rebar?

Rental places generally don't rent SDS bits, especially ones as small as 3/16". They don't cost much though.

That was my thought but I didn't have any other bits so I couldn't try another hole

Yeah, for 3/16" hole, only 2" deep, any hammer drill should do. go buy a cheap corded skil or HF if your 18v isnt working correctly
I used to have the cheapest skil you could buy and it would slice through with 1/2" bits

Unless they hit aggregate. Typical cordless hammer drills don't have much impact energy, just a pair of serrated rings with a spring and clutch and rely on high BPM, ok for mortar, bricks, CMU, but not concrete. Rotary hammers hit harder and the drive of the bits is designed for getting through aggregate and sometimes rebar. Even a cheap HF rotary hammer will run circles around the best cordless hammer drill in concrete.

Rent a good drill from Home Depot. What you are using just don't have the arse to do it right. Another thing, how old is the concrete? Sounds like that slab has been down a long time. The older concrete gets, the harder it gets.
Oh, do anchor it down. Wind will lift 800lbs very easy.

Where are you? All aggregates are not equal. Limestone will cut like butter. Some of the river gravel is so hard, it can be near impossible to drill.

I'm in Southwest Arkansas. Concrete is about 10 years old

I have a hammer drill that works great.
But, when I tried it on a friend's concrete driveway, it wouldn't do anything.

Harbor freight 80 bucks you always can use a hammer drill rental will be that much

If you or a neighbor have an electric hammer drill try it.
This may work with your old bit but I suggest getting a new one. Get a glass of water and place next to where you are drilling. Every 30 seconds or so stop drilling and put about an inch of the bit in the water to cool it off. After 10 or 15 seconds take out of the water and start drilling again.

Rent a better drill from Home Depot. I did something similar and it took me 20 minutes for a dozen holes with the bit they gave me.
