flap wheels

Specification Highlights:

• Types of Flap Wheels:

  • Spindle-Mounted Flap Wheels – with a built-in shaft for handheld tools

  • Unmounted Flap Wheels – for bench or pedestal grinders

  • Interleaf Flap Wheels – alternate abrasive and non-woven flaps for fine finishing

  • Conical / Fan-shaped Flap Wheels – for internal or narrow surface grinding

• Abrasive Materials:

  • Aluminum Oxide – general-purpose use on metal and wood

  • Zirconia Alumina – high stock removal, long life

  • Ceramic – for hard metals and aggressive grinding

  • Silicon Carbide – for stone, glass, and non-ferrous metals

• Grit Range:

  • Coarse (40–60 grit) – for heavy material removal

  • Medium (80–120 grit) – for blending and shaping

  • Fine (150–400 grit) – for polishing and surface preparation

• Common Sizes (Diameter × Width × Shaft/Bore):

  • 25 × 25 mm × 6 mm shaft

  • 50 × 25 mm × 6 mm shaft

  • 100 × 50 mm × 13 mm bore

  • 150 × 50 mm × 20 mm bore
    (Custom sizes available for specific applications)

• Operating Speed (RPM):

  • Varies by size; common ranges:

    • Spindle-mounted: up to 12,000 RPM

    • Unmounted (large wheels): up to 3,000 RPM

  • Must match tool and wheel specification to avoid breakage

• Mounting Options:

  • Spindle/shank-mounted (6 mm or 1/4” shaft)

  • Center-hole/bore-mounted for arbor grinders

• Applications:

  • Rust and paint removal

  • Weld seam blending

  • Deburring machined parts

  • Surface cleaning and preparation before coating

  • Finishing irregular shapes and contours

• Key Features:

  • Flexible flaps conform to surface irregularities

  • Continuous abrasive exposure as flaps wear down

  • Cool cutting action reduces heat and discoloration

  • Available in various densities for aggressive or fine work

  • No clogging, self-renewing abrasive structure

  • Ideal for manual and automated processes
