Snail Lock Rules!!

by TZ -

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.

Worked Really Well

by Don

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.
