Video: Extending life of abrasive cut-off wheels

I am a retired Tile Setter and have always set the diamond blade height at minimum cut depth to complete the cut. If there was a depth gauge or stop that was used on a cut-off grinder, I'm sure the blade would last longer and a quicker cut. Not only will the blade last longer, but less chance of binding, which is the reason for rapid ware and blade exploding.
