trying to hang shelves on a concrete wall. Using carbide drill bit we were told to use from big box store along with screws. Is it supposed to be this hard. tried battery power drill first. thought maybe not enough power , so used a corded drill. still felt like I was getting nowhere . DomI just keep drilling.

You might see if you can rent a hammer drill in your area, or borrow one from a particularly handy neighbor. That could make it easier.

Exactly correct Steve. The carbide drill is useless without the hammer drill. You simply cannot put enough pressure on the drill to allow the bit to drill into the block or cement. And if its solid concrete, you will burn up the bit long before you get one hole done. The hammer drill not only turns but it vibrates the drill against the wall causing the carbide bit to bite into the cement. Once you see how easy this is you will be amazed how fast it will work. Rental shops carry this type of drill for only around $20 for two or four hours time.

thanks guys, I knew something was not right with this picture. So, do you think we have already burned up this drill bit. I guess my own answer is go ahead and get another drill bit and really make it easy

Electric....I have 3 hammer drills. Two matching Dewalt 18 Volt cordless ones...and a big bad boy corded version. I'm assuming you are going to install some blue tapcon type screws?

Electrical like KMS said. I is not to big of a drill to use. I doubt they rent the battery types anyway. It is typically a little larger then a regular drill that you may be using now. They also may end up renting you a slightly larger drill not at all like the one you are familiar using. They will show you how to use it, but other then being a bit bigger it pretty much works exactly the same and those you have now other then hammer.

Thanks you guys, yes, We bought the Blue tapcon screws and the drill bit even comes with the screws. I guess my next question. I just asked one of my handy friends. He did not have one, but said I needed a masonry/brick drill bit that carbide was for metal. So, do you think we are using the wrong drill bit too.

No TAPCONS are used for cement. You have the correct drill bit. You must get the hammer drill for this to work. You can tell if its the correct drill bit by the end of it. There should be two little pieces of metal, not real sharp like a normal drill that appear to be fastened to the end of the bit. That is the carbide cutting head.

thank you guys mission accomplished. my husband was able to borrow one from work and surprising how easy it was when you have right equipment. Also if I could put a plug in for the habitat restore stores. we went to one in our town on saturday and they had things marked down 50%. we found a gladiator garage wall system for 20 dollars. If you have never checked one out it is great and the money goes back to supporting the work of building more homes.

As another plug for the habitat stores..... the one nearest me also rents tools at rate less than most other places.

That's great, Betty. Glad you got the problem solved. Now you're ready for the shelves. Kevin, you and I need to look into getting a commission from Habitat for all the plugs we give them around here.
