Alpha® VFlex™ Flexible Diamond Sanding Disc

The Alpha® VFlex™ flexible diamond sanding disc is built for paint, coating, oxide and rust removal, plus burr grinding and chamfering on steel, stainless steel and contoured surfaces. A rubber-sandwich body lets the disc conform to curves while dramatically reducing noise and vibration — an everyday improvement over rigid discs on irregular work. It also runs cleanly on stone, ceramic, composite, cast iron and glass. Every size, grit and arbor in the table below is made for high-speed angle grinders.

Features

  • Flexible rubber-sandwich body conforms to contoured and irregular surfaces
  • Removes paint, coatings, oxide and rust from steel and stainless steel
  • Deburrs and chamfers metal edges without clogging
  • Also shapes natural stone, engineered stone/quartz, ceramic, composite, cast iron and glass
  • Rubber damping dramatically reduces operator-felt noise and vibration
  • Long life and consistent cut reduce downtime and tool changes
  • Available 5" with 7/8" arbor or 5/8"-11 zinc hub, and 7" with 5/8"-11 zinc hub

  1. Confirm the disc diameter and arbor match your tool (see Models / Part Numbers).
  2. Mount on a high-speed angle grinder, sander or polisher using the tool's original flange and lock nut (7/8" arbor) or thread directly onto a 5/8"-11 spindle (zinc-hub models).
  3. Verify grinder no-load RPM does not exceed 5,000 RPM — the maximum for all VFlex sizes.
  4. Start with #35 grit for aggressive stock removal, #50 for general purpose, #80 for finer finish work.
  5. Run dry, or feed water at the disc face to suppress dust.
  6. For virtually dust-free grinding on stone, pair with an Ecoguard dust shroud and HEPA vacuum. Note: some metal powders are combustible — verify material safety before vacuum collection.
  7. Apply light, even pressure and let the flexible body match the work surface — pressing hard reduces life and cut quality.
  8. Inspect the disc before each use; replace if torn, glazed or worn below useful diamond depth.

What is the VFlex disc designed to do?

Paint, coating, oxide and rust removal; burr grinding and edge chamfering on steel, stainless steel and contoured surfaces. It also runs on stone, ceramic, composite, cast iron and glass.

How is VFlex different from a rigid disc?

The VFlex has a flexible rubber-sandwich body that conforms to curves and irregular surfaces. It cuts cleaner on contoured work and reduces noise and vibration compared to a rigid disc.

Can I run VFlex wet?

Yes — VFlex works dry or with water fed at the disc face to suppress dust.

What max RPM should I set?

Maximum 5,000 RPM for all VFlex sizes (5" and 7"). Confirm your grinder no-load speed before mounting.

Which grit should I choose?

#35 for aggressive stock removal, #50 for general purpose, #80 for finer finishing.

Can I use VFlex for dust-free grinding?

Pair the VFlex with an Alpha Ecoguard dust shroud and a HEPA vacuum for virtually dust-free operation on stone. For metal grinding, confirm the metal powder is safe to collect with a vacuum — some are combustible.
