I tried drilling into my patio concrete with a hammer drill. Did not even cut into the concrete. They just burned up. Highly not to buy.

Used with a hammer drill and got no more than 1/4 inch into concrete.

I recently purchased an electrical cord reel to mount on the cement block wall of my garage. The reel came with 10mm masonry wall anchors and I didn’t have a 10mm masonry bit so I ordered this one. When I attempted to drill the first of 4 mounting holes, I chucked this bit in my corded Dewalt 3/8 VSR 8 amp drill and tried to start the hole in the concrete block. The first thing I noticed was it very difficult to keep the bit from wandering away from my mark so I just let it pick it’s own spot and started drilling. I drilled for a good length of time with both medium and firm pressure and when I checked the progress, the bit had only made about a 3/8th inch divot. Not satisfied with the slow progress, I fetched an old 3/8” cheap masonry bit (top in photo) that I had bought about 20 years ago from Lowes to drill several holes in a concrete pad. Even though this bit was well used and a little smaller diameter than the 10mm needed, I thought I might try to make pilot holes for the 10mm bit. The old 3/8 bit didn’t wander off my mark and made short work of drilling the 4 holes, penetrating reasonably fast with medium pressure. As it turned out, I didn’t need to chase these holes with the 10mm bit, as the old 3/8 bit wallowed holes big enough for the anchors to fit in. Maybe this 10mm bit would have worked better in an impact drill but it was a total failure for me.
