(I'm good with drilling into wood and drywall, but have struggled to drill into concrete...)
Tried to mount something (device to be attached with screws) to our concrete foundation.
Used a good (corded) drill + masonry bit(s), but the problem is it's very hard to get the holes started at the correct, precise position. For drilling one hole this isn't such a big problem, but when trying to mount something that takes 4 screws at the ~corners, the misalignment of the holes is an issue.
Should I be using a hammer drill (I don't own one at present)?
Specialized bits?
Start with really small pilot holes (I started with a fairly big hole, ~1/4")
===
Is there an easy way to cover past hole mistakes - a putty/filler that is a good match for concrete color and/or slightly stainable if mine is a little darker/lighter than the default?
===
The thing I was trying to mount came with 4 plastic plugs + 4 metal screws. I think the idea is drill the hole, put in the plug, then drill the metal screw into the plug. I ~ruined at least one of these plugs on a mis-drilled hole. At the hardware store, I didn't see new equivalents of this - most stuff for going into concrete was all-metal and really big diameter (screws and/or other widgets). I can't use screws with really big heads, because for the thing I'm trying to mount, it's designed to mount on small-ish screw heads. Suggestions?
