A most excellent set of blades if you want to cut installed glass without breaking or chipping it. The blades actually allowed me to cut a mirror that was installed on a wall without removing the mirror. I had read online that it was not possible to do this but these blades, mounted on a Makita Angle Grinder did the trick, with no drama. Save a lot of $$, time and labor in not having to remove the mirror, etc...Be sure to wear goggles and a mask when cutting glass and pay attention to the direction of rotation of the blade when cutting.

These worked perfectly. I used to cut a square out of a mirror.

I guess this should work but did not realize I had tempered glass which can not be cut. when I touched the glass with these blades on my grinder, it shattered.
