Worked Really Well

Boy this was expensive, but they made my work very easy. I thought such a small item should not cost that much.

I tiled my bathroom with marble and needed to make an edge treatment where the tile ended and the wallboard began. I cut 2 inch strips of tile from the 12 inch squares and then cut a 45 degree and 22.5 degree angle to approximate a round edge.

Then using 5 polishing pads with this adapter made it easy to start with the roughest pad and work down to the smoothest pad to make a nice round shiny edge.

I clamped each piece as they would be next to each other on the wall to a 2 by 4 with a wood strip so that all the bottoms lined up and then ground the individual tiles to match each other.

Also I have never worked with tile before let alone marble and the job came out very professional.

Snail Lock Rules!!

by - verified purchaser
In my opinion, these are the best. The snail lock is awesome. They never come off in use, and are super quick to change pads.
