“This tool work great! Perfect for grinding out mortar joints. I removed the crumbling mortar joints on my blue slate walkway and re mortared the joints.

“Core diamond bit did an acceptable job on specifically Magnesia bricks, but holes were not very clean, some chipping ocurr when core bit was going into brick and much more going out brick. Core bits vibrates a little bit.”
“So far we haven't used the core bits yet. However they have a good variety of sizes which was very interesting to our business. Ordering was easy price was reasonable and we received the product very quickly. Well write a review as soon as we use the bits”
“For the money, it was the best choice for my particular job. It drilled a very smooth 4-1/2” hole through a cinder block wall. As we were about to punch through, the core bit seized! The shank on the arbor broke. This saved my drill and probably my arm from being broken, so kudos for design. The core bit itself is light weight, but it isn’t welded at the top. It seems to be press fitted. It did work, but how???
Anyway, it drilled a nice hole. Think safety.”
“the 1 3/4" dry bit and centering bit worked great, once it got started into the block it went through very cleanly and true.
Great product I will buy more as the need arises.
Thanks.”
