A 4.5-inch diamond glass cutting blade is an ultra-thin, continuous-rim disc designed to slice through glass, tile, and crystal with minimal chipping. Typically used with a standard angle grinder, it operates best at high speeds to deliver clean, polished edges without secondary grinding.Top FeaturesUltra-Thin Profile: Usually between 1.0mm and 1.4mm thick to minimize material waste and prevent the glass from cracking.Continuous Rim: Unlike segmented masonry blades, they lack teeth, which allows for a smooth, continuous grinding action through fragile Operation: Can be used dry for quick cuts or wet to suppress dust, prevent overheating, and extend the blade's lifespan.
