Flap Discs

Description

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

• 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.
