I’m a hobbyist so can’t buy an expensive tile saw but know I need a good blade. Would blade work with the Harbor Freight DIAMONDBACK 7 In. Heavy Duty Wet Tile Saw With Sliding Table? Also, if I get only 1 blade, should I get this one or a medium blade? Thanks in advance!

Most any decent wet saw will work well with glass. I recommend you going through our video on water use to make sure that it provides enough water:

For a good all around blade for glass, I would recommend the Result Diamond Blade:
