Can it be used to repair holes in concrete?

Yes it can be used to fill holes in concrete. If the hole is less than 3/4 inch I think the liquid repair is preferred. The liquid does best to repair cracks.

I wouldn't think so. It hardens up fast and does a great job sealing up holes but I dont think it would do what your wanting it to do.

I would guess it would depend on how deep. I've used mine to drill about (14) 1/2 inch x 4 inches deep holes into concrete without a problem.

It could, but you'd have to buy different screws that could anchor into cement.

I wouldn't see why not. I used it to repair cracks in my outdoor pool deck. It worked great. Watch the u tube video. Very helpful.

In principle, yes. I have drilled some 5/32" holes in concrete with this drill, although I would recommend a larger drill (perhaps 10 amps) if you need to do a lot of heavy drilling. Depending on the volume of your work, you may consider a percussion drill as well.

It works great on concrete for small holes. The new one is excellent, I would still be using my old one if it hadn't been underwater for a few days, never had a problem with it until that happened. Richard K

Thank you for your interest. Yes, the Bosch HD21-2 would work for drilling holes into concrete with the proper bit as long as the diameter of the hole is not larger than 7/8" which is the maximum capacity for this hammer drill. If you need to drill larger diameter holes we would recommend one of our larger rotary hammers. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

Yes. There are holes for the pin anchors in each foot You could drill holes in the concrete, insert an anchor and put a screw through the hole on the foot into the anchor.

Not sure. We are a pro concrete cutting and coring company. We use to break out cut concrete. But they do have quite a few attachments that may be used for more delicate operations. I'd google or check with online forums to see what's best if I were you. Right tools for the job is essential. You don't want to go whaling with a fork and spoon. Best of luck.

No-- the way the kit is set up you need to drill into concrete and wedge provided plastic anchor inserts into the hole. The screws provided then screw into the anchors to tighten. If you buy concrete screws you can drill a pilot hole and then screw the screws directly into the concrete without using anchors. The concrete screws create threads in the concrete as you screw them in. You can then unscrew them and screw them back in at any time because the threads are permanently etched into your concrete holes. Click on my review for more detail.

The holes would need to be no more than 1/4" around. Hope this helps. It is a great tool!!!

As long as you use concrete screws instead of the screws provided, I don't see why it wouldn't work.

I have used it to repair concrete and it works great. I use it primarily to repair the grout lines between the tiles in my swimming pool so I would imagine that it would work with masonry as well. I would be more concerned about the color match though as its color fades over time and if you have textured masonry (like stucco) you can definitely see where it was repaired even if you rough it up to look like stucco and paint it.

I believe it comes with something so you can patch it up....if not you could go to a store and find something to cover the hole and find some glue.

i have not used my ps31-2a 12 for drilling in concrete, because i have a bosch hammer drill that does a great job in concrete. i would expect that this drill would work fine with a good sharp concrete bit, and drilling smaller holes. if you are planning to drill larger holes and deep holes, you should use a larger drill preferably a hammer drill.

Yes. I've used it outside to replace missing mortar, reset a few loose bricks, and to patch cracks. It has worked very well for me.
