This tool was complete and packaged well. This is a project that I was dreading doing because I was afraid it was going to be a struggle and look ugly when done not to mention take forever. I was wrong. I was drilling through cinder block on the outside and on the inside what 2 x 4 stud with sheet rock. I tried to center on the cinder block to prevent hitting the rib of the cinder block. turns out this type block was different than any cinder block I have ever seen. Turns out there were two ribs and I hit them both. I began from the outside and drilled as far as I could. Then I took a sharp 1/4" rod and drove it through to the inside to see where the pilot hole of the hole saw should begin. Turns out there was a wood stud that was along one side and no way avoid it. I ran the hole saw enough to mark the stud showing where the drill needed to cut. I drilled a bunch of holes in the groove the saw made through the stud as close together as I could. Then used the whole saw to do the rest. It worked fine. In the cinder block the saw cut so smooth and easy. It didn't take long at all. It is too bad I will never use it again because it would cut many holes with ease.

Drilled through a 22" thick brick wall like butter.

Have used it twice with total satisfaction on stucco and concrete. However, the grub nut rattles out, easily fixed with loctite.

No arbor---no guiding drill bit--you can't do anything with this.

I only needed to drill through 1 concrete block and the tool worked fine. The tool came with 2 pilots drills and 10 mm wrench for tightening. Cut through the block easily. Not sure if this would hold up to constant abuse but works good and a great value for a job or two

I’ll give it three stars. It’s a sturdy tool but it just didn’t do the job. I couldn’t get it to cut brick. I used a corded Bosch drill and tried water as it was turning.

Needed a 4-1/4" core. The top brand we professionals know and trust doesn't make one in the size. 110mm is close enough. I've used this one on 4 brick and CMU walls. One tooth is loose and going to fall out next use. And the centering bit is held in place by a set screw. It comes loose within minutes of starting. I ground a notch in the bit at the screw contact, then secured it with tape so when the set screw comes loose, the bit doesn't fall out again. I doubt I will get more than 5 more uses out of this tool. Like a said, great for homeowners but not a professional who will need it for dozens of holes like we do.

This took about 20 minutes. I ran water as I was boring through this ditch. I've been redoing the drainage system next to the home we bought. I want one exit into the cement ditch. Not only did it cut through the cement buy through what looks like cattle fencing in the cement. My choice was this for cheap on here or 200 for milwaukee at homedepot. By this one!
