The Alpha® 7" Vexcel Rigid Grinding Disc is designed for general purpose, heavy duty material removal applications whether it is concrete, cast iron, steel, stainless steel, non-ferrous metals, metal alloys, carbon fiber reinforcement plastic (CFRP), glass fiber reinforcement plastic (GFRP), natural and engineered stones. The rigid, steel base with a curved design creates a very aggressive grinding action and the fluoric rubber backing reduces noise and vibration. It minimizes sparking so you can avoid toxic air and pollution. The Vexcel's heavy duty multi-layers of diamond grits ensure aggressive material removal and long product life.
The Vexcel grinding wheel is available in 4.5”, 5” and 7” with 7/8” arbor or with 5/8”-11 zinc hub. Ideally used with the Alpha 5" High-Speed Angle Grinder HSG-125.
