Flat Diamond Grinding Disc for Metal Preparation Alpha® Vextra Flat Grinding Discs are aggressive diamond grinder discs for steel, stainless steel, and non-ferrous metals. Their optimized diamond grit and layer arrangement provides consistent grinding performance and long service life, while the flat grinding design maximizes surface coverage for efficient material removal. Remove Rust, Mill Scale, Paint and Adhesives Vextra removes rust, burrs, mill scale, and paint from metal surfaces without quickly clogging the grinding face. The disc also removes epoxy, glue, and adhesives, making it useful for surface preparation and coating removal applications where conventional grinder wheels may require frequent replacement. Reduced Grinding Noise and Vibration A rubber sandwich construction reduces disc weight, vibration, and operating noise while maintaining aggressive grinding performance. This design helps reduce operator fatigue and limits downtime associated with frequently replacing conventional abrasive discs. Multiple Sizes, Grits and Arbor Configurations Vextra Flat Grinding Discs are available in 4-1/2", 5", and 7" diameters with 35, 50, and 80 grit options. Depending on the selected model, discs have either a 7/8" arbor or a 5/8"-11 zinc hub. In addition to metal, Vextra can grind natural stone, engineered stone and quartz surfaces, wood, and rubber.
