best way to remove nails in concrete block


I took off a bunch of furring strips so I could build a true 2x4 wall in front of a concrete block wall, but now there is 4 nails per strip left in the block, what is the best way to remove these? or at least get rid of the part that is sticking out?

You may also try knocking them back and forth with a hammer until they loosen up enough to pull them out - or they break off at the wall. That may cause some minor chipping as well though.

Standard metal cutting disk.

Get an angle grinder in your tool arsenol, you will thank yourself.
I went along time without one, now that I bought one (now several) I use it frequently.

Thin (.040) cutting disk would be the best.

Definitely agree with this. Used to use a recip saw for nails and thought it worked pretty good, but the grinder blows right through them and is far more controllable.

I tried a recip saw already, hated it way to slow for me

it's just a really thing disk. It doesn't have the rought grooves on the ont he flat part like a grinding disk does.

If they are cut concrete nails they will break off instead of bend. I have an old diamond tile cutting disk on my grinder and it cuts nails or anything else great.

to make it go faster I used a cutting disc to cut a groove in the nail, then two taps of a hammer it broke off right at the slit, saved time grinding, about 5 seconds a nail to remove, major speed improvement over a recip saw or crow bar

I used a diamond blade to slice through a 4" cast iron drain pipe once--It didn't seem to hurt the thing at all.

Mike, I have used the old diamond disk to sharpen my lawn mower blades also.

One strange thing I did a few years back was with a drimmel. I had a dozer and I had to take the track off to get to the bull gear in the final drive. I didn't have my grinder there so I use a metal cutting disk on my drimmel to cut the wield on the pin so I could get the track off, worked like a charm.
