LUNVITO Glass Cutting Disc 5 Pcs – Diamond Cutting Blades for 4 Inch x 7/8 Inch Angle Grinder

Meet the LUNVITO Glass Cutting Disc 5-pack, a set of ultra-thin diamond blades designed for 4-inch or 4.5-inch angle grinders and marble machines. Each blade features a precise 0.055-inch thickness and a 7/8-inch arbor hole, delivering clean, straight cuts on glass-based materials with minimal edge damage. The discs are engineered for both accuracy and durability, so you can tackle projects from glass bottles to ceramic tiles with measured, confident motion.

Crafted with premium diamond material and advanced processing, these discs resist heat buildup during cutting, helping maintain a steady cutting rhythm. The ultra-thin profile reduces vibration and chatter, supporting smoother finishes and less fatigue over longer sessions. The 5-pack design provides ready-to-use blades and conversion washers (4/5-inch and 5/8-inch bore) to fit common grinder configurations, reducing downtime and guesswork on site.
