Review on Universal Oscillating HEMUNC Semicircle Triangular by Paul Milonas

I bought these to remove a thin layer after removing some improperly installed floor tiles. I tried 60 grit sandpaper and it worked but wore out in seconds so I took a chance. The delivery was fast! This product worked well and cut through a thin layer fairly quickly. After sanding down a thin layer to where other 6" x 12" tiles could be installed, the head showed little to no signs of wear. I'm happy. The heads fit perfectly on my "Rigid" multi-tool. I just wish the Delta head was a little tighter to cut through a little faster, but maybe I'm just impatient. Overall I am very happy with my purchase.
