Flap Wheel

Introduction

A flap wheel is an abrasive tool made of multiple abrasive cloth flaps radially attached around a hub. It is widely used for grinding, deburring, weld seam finishing, rust removal, and polishing on stainless steel, carbon steel, aluminum, and other alloys.

Types of Flap Wheels

1. By Shape

   • Flat Flap Wheel (T27): Best for flat surfaces and light contouring

   • Conical Flap Wheel (T29): Angled design, ideal for curved surfaces and weld seams

2. By Material

   • Aluminum Oxide Flap Wheel: For general steel and wood

   • Zirconia Flap Wheel: For stainless steel and alloys

   • Ceramic Flap Wheel: Strong cutting ability for high-hardness metals

3. By Number of Flaps (Pages)

   • 60 Flaps: Aggressive grinding, fast material removal

   • 72 Flaps: Balanced performance and durability

   • 90 Flaps: Longer life, finer finishing

4. By Grit Size

   • Coarse (P40–P80): Heavy stock removal, weld grinding

   • Medium (P120–P240): Surface leveling, satin finish

   • Fine (P320–P600+): Fine polishing, reduced roughness

Applications

• Stainless steel weld seam finishing

• Tank, pipe, and dished head polishing

• Pressure vessel and chemical equipment finishing

• Deburring and surface treatment of metal parts
