  • Product Category: Abrasive Tools
  • Flap Discs are versatile abrasive tools designed for grinding, blending, and finishing applications. Comprising overlapping abrasive cloth flaps attached to a backing plate, they provide excellent material removal rates while ensuring a smooth and consistent finish. Flap discs are widely used in metalworking, fabrication, and automotive industries for tasks like deburring, rust removal, weld seam blending, and edge chamfering. The durable and flexible structure of the flaps ensures long-lasting performance and minimal tool changes, making them a preferred choice over traditional grinding wheels and fiber discs.
  • Key Features:
  • Overlapping Flaps: The design of layered abrasive cloth flaps ensures continuous exposure of new abrasive material, extending the life of the disc and improving efficiency.
  • Multi-Functionality: Combines aggressive stock removal and fine finishing in one tool, reducing the need for multiple disc changes.
  • High Durability: The sturdy backing plate, combined with premium abrasive grains, ensures long-lasting performance and wear resistance.
  • Cooler Grinding: The flexible flap structure provides cooler cutting action compared to grinding wheels, reducing heat build-up and minimizing the risk of warping the workpiece.
  • Consistent Finish: Ensures a uniform surface finish, even on irregular or contoured surfaces.

Applications:

Metal Grinding and Finishing: Ideal for grinding, deburring, and finishing steel, stainless steel, aluminum, and other metals.

Weld Seam Blending: Perfect for smoothing weld seams and removing weld splatter in metal fabrication.

Rust and Paint Removal: Efficiently removes rust, paint, and surface contaminants from metal surfaces.

Edge Chamfering: Great for edge grinding and chamfering on metal plates and workpieces.

Surface Preparation: Prepares surfaces for painting, coating, or further finishing processes.

Technical Specifications:

Abrasive Material: Available in various abrasive grains, such as aluminum oxide, zirconia alumina, and ceramic for different applications

Backing Material: Typically made of fiberglass, plastic, or metal for rigidity and durability

Grit Sizes: Wide range of grit sizes from coarse (P36, P40) to fine (P120, P240), allowing for different levels of stock removal and finishing

Disc Diameter: Available in standard sizes such as 4-1/2", 5", 7", and 9" to fit various angle grinders

Max RPM: Rated for high-speed operation, typically up to 13,000 RPM, depending on the disc size and material

Types of Flap Discs：

Flat (T27): Designed for working on flat surfaces, providing maximum contact with the workpiece, making it ideal for grinding and smoothing.

Conical (T29): The angled shape provides better access to contours and edges, ideal for heavy stock removal on flat or curved surfaces.

High-Density (HD): Features more abrasive flaps for longer disc life and enhanced material removal, often used in more demanding applications.

Advantages：

Increased Productivity: The combination of grinding and finishing capabilities in one disc reduces the need for tool changes, improving efficiency.

Long Lifespan: The overlapping flap design continuously exposes fresh abrasive material, resulting in extended disc life compared to conventional abrasives.

Smooth Finishes: Provides a consistent finish while removing material, making it suitable for both rough grinding and final finishing.

Reduced Vibration: The flexible flaps absorb vibrations, providing smoother operation and reducing operator fatigue.

Minimal Heat Generation: Cooler grinding action reduces heat buildup, protecting heat-sensitive materials from damage.

Packaging：
Available in individual discs, multipacks, or bulk boxes, with custom packaging available upon request to meet specific customer needs.
Storage:

Store in a cool, dry place, away from direct sunlight or moisture, to maintain the disc's integrity and performance. Keep discs in their original packaging to prevent contamination or damage to the abrasive surface.
