Material: Constructed with premium aluminum oxide or zirconia alumina abrasive flaps bonded to a rigid, flat fiberglass backing pad for enhanced durability and stability.
Design: Features a unique flat fiberglass backing plate with radially arranged overlapping abrasive flaps, combining the benefits of a grinding wheel and flap disc for aggressive material removal with smooth
finishing.
Applications: Ideal for heavy-duty grinding, weld removal, and surface blending on metals (steel, stainless steel, alloys) and composites in industrial and fabrication settings.
Compatibility: Designed for angle grinders (common sizes: 4.5"/115mm, 5"/125mm, 7"/180mm) .
Advantages:
Flat Fiberglass Backing - Provides superior rigidity for aggressive grinding without flexing
Dual-Action Performance - Combines fast stock removal of grinding wheels with finishing capability of flap discs
Enhanced Control - Flat profile improves stability and reduces vibration during operation
Cooler Operation - Open flap design allows better heat dissipation than solid grinding wheels
Versatile Grit Range - Available from coarse (40 grit) to fine (120 grit) for various applications
Product Features：
It is a comprehensive product specifically designed for surface treatment of workpieces with special shapes such as thin walls, grooves, and crevices. The product is lightweight, ultra-thin, elastic, has good synchronous consumption, and does not turn black when grinding stainless steel.
The product is mainly used for grinding various thin-walled metal parts, grooves and crevices with a spacing of less than 5mm, inner and outer R surfaces, small R surfaces at connection points, and stainless steel workpieces.
It is widely applied in the grinding and polishing of engine blocks, stainless steel kitchen and bathroom fixtures, stainless steel furniture, outdoor aluminum furniture, door industry, decoration and renovation, as well as various sheet metal products.
