best to watch this with safety glasses already on. When using this method of sharpening your core drill bit please take all precautions. In the Picture is a grinder and the video is one of the crew sharpening a 7 inch core bit. what you want to do is make scores across the diamond embedded teeth, not to many but just enough to be able to let new metal become exposed and wear away as the core drill bit cuts the concrete hole. The hammer method is not quite as effective but works just a well in a pinch.
