Cut shapes from the middle of your glass without having to cut in from the edge! Instead of your piece seperating, the blade does. Drill a hole and thread the separating blade through.
For internal cuts, omni-directional. The Separating blade is the same size as the Standard blade and has exactly the same cutting action. The difference is that the Separating Blade has a coupling attached to it which allows you to open the blade, slide it through the piece, reattach it and make internal cuts with no entry point.
