Alpha Vextra Flat Disc is a grinding disc designed for steel, stainless steel, non-ferrous metals, and general-purpose surface preparation. It is used for material removal, rust removal, paint stripping, and grinding epoxy, glues, and adhesives without clogging the grinding surface.
The disc uses an optimized diamond grit arrangement combined with a sandwich-style construction incorporating rubber layers. This design helps reduce vibration and operating noise while maintaining consistent grinding performance across extended service life. The disc is intended for flat grinding to maximize usable surface area and improve productivity.
In addition to metal applications, the disc can be used on natural stone, engineered stone and quartz surfaces, wood, and rubber. Multiple sizes, arbor configurations, and grit options are available to support different grinders and material removal requirements.
