4 Inch x 106 Inch 60 Grit Silicon Carbide Belt Second
Silicon Carbide abrasive belts for the upright belt sanders like the Somoca and Bee Metal Sander are an economical and efficient way to grind your glass. For most purposes, silicon carbide belts may be the only belts you'll ever need. They are easy to use and work well on your glass. They will wear down faster than diamond belts and give a less consistent surface grind as they start off more aggressive and then become less and less aggressive very quickly.
These belts are from 2018 so the joint adhesive has an unknown lifespan left in it. They should still work quite well but may not last through the entire lifespan of the belt.
