Professional Flap Discs — Grind & Finish in One Step

USA1 Abrasives Flap Discs combine the aggressive cutting action of a grinding disc with the smooth finishing capability of a sanding disc — all in one tool. Overlapping abrasive flaps continuously expose fresh cutting edges as the disc wears, delivering consistent performance from first use to last. Eliminate the time-consuming step of switching between grinding and finishing discs.

Technical Specifications

  • Abrasive Material: Aluminum oxide (zirconia options available)
  • Backing: Fiberglass backing plate
  • Disc Type: Type 27 (flat) for flat surface work
  • Arbor Hole: 7/8" center hole
  • Max RPM: 12,200 RPM
  • Application: Dry grinding and finishing

Key Features & Benefits

  • 2-in-1 Performance: Grinds and finishes in a single pass — saves time and tool changes
  • Self-Renewing Abrasive: Overlapping flaps expose fresh abrasive as the disc wears
  • Consistent Finish: Produces a smoother finish than grinding wheels
  • Cooler Cutting: Flap design dissipates heat better than solid grinding discs
  • Less Vibration: Flexible flaps reduce vibration and operator fatigue
  • Long Disc Life: More abrasive material means longer use before replacement
  • Versatile: Works on steel, stainless steel, aluminum, and wood

Recommended Applications

  • Weld blending and smoothing on steel and stainless
  • Rust and scale removal
  • Paint and coating removal
  • Surface preparation before painting or coating
  • Deburring and edge cleanup
  • Aluminum and non-ferrous metal finishing
  • Wood shaping and stock removal

Flap Disc vs. Grinding Wheel

  • Choose Flap Discs when: You need to grind and finish in one step, want a smoother finish, or need to reduce vibration and heat
  • Choose Grinding Wheels when: Maximum material removal speed is the priority

Grit Selection Guide

  • 40-60 Grit: Heavy grinding, weld removal, aggressive shaping
  • 80 Grit: General purpose grinding and blending
  • 120 Grit: Light blending and surface conditioning

Always wear appropriate PPE including eye protection, gloves, and hearing protection when using angle grinders.

Grind. Blend. Finish. One Disc Does It All.
