Types of Flap Discs Available:
Aluminium Oxide Flap Discs:
Suitable for general-purpose grinding and finishing applications. These discs are widely used for mild steel, fabrication work, and routine industrial operations where consistent performance and cost efficiency are important.
Zirconia Flap Discs:
Designed for heavy-duty grinding applications that require faster material removal and longer disc life. These discs perform exceptionally well on stainless steel, alloy steel, and other hard metals.
Type 27 (Flat) Flap Discs:
Type 27 flap discs are ideal for flat surface grinding, blending, and finishing. They provide excellent control while producing a smooth, uniform finish.
Type 29 (Conical) Flap Discs:
Type 29 flap discs are designed for aggressive grinding on edges, weld seams, corners, and curved surfaces. Their angled design allows higher stock removal while maintaining operator control.
Why Choose Our Flap Discs?
High Material Removal Rate
Premium abrasive grains provide fast cutting action for efficient grinding and reduced processing time.
Longer Disc Life
The layered flap construction wears evenly, extending the usable life of the disc compared to conventional grinding wheels.
Consistent Surface Finish
Produces smooth, uniform finishes while reducing the need for additional finishing operations.
Reduced Heat Generation
The flap design improves airflow during grinding, helping minimise heat build-up and reducing the risk of workpiece discolouration.
Strong Fiberglass Backing
Durable fiberglass backing provides stability, strength, and safe operation during high-speed grinding.
Versatile Performance
Suitable for grinding, blending, deburring, rust removal, edge finishing, and surface preparation across various metalworking applications.
Common Applications Flap Discs
Flap discs are widely used across multiple industries for grinding and finishing metal components.
Weld Grinding and Blending
Smooths weld joints and blends welded surfaces for a clean, professional finish.
Surface Grinding
Removes excess material while creating smooth, even metal surfaces.
Deburring and Edge Finishing
Eliminates burrs and sharp edges after cutting, machining, or fabrication.
Rust, Paint and Coating Removal
Effectively removes rust, oxidation, paint, and coatings from metal surfaces before refinishing.
Fabrication Work
Widely used in fabrication workshops for structural steel, sheet metal, and industrial component finishing.
