50 Pieces 5 Inch 125mm Abrasive Flap Discs for Angle Grinder – 80 Grit

Tackle rust, deburring, paint removal, weld blending, and precise edge work with a dependable pack of 50 flap discs designed for standard 5" angle grinders. Each disc uses durable aluminum oxide abrasive on a glass fiber backing, engineered for strong tensile strength and long wear life to keep pace with demanding metal and wood finishing projects.

• 125mm (5") diameter with a 22mm bore to suit common angle grinders.
• Aluminum oxide coated abrasive at 80 grit for balanced stock removal and a smooth finish.
• Glass fiber backing bonded with durable adhesive for stable grinding and extended disc life.
• 50 pieces in a single bundle, ready for large projects without frequent replacements.
• Effective on metal and wood surfaces — ideal for surface rust removal, deburring, paint stripping, weld blending, edge chamfering/beveling, and finishing work.

Designed for reliable performance across contours and flat surfaces, these flap discs provide consistent material removal with a controlled, uniform finish. The flap arrangement maintains cutting efficiency while reducing heat buildup, helping you avoid warping and scorching on delicate materials.

Why this pack stands out

Compared with standard discs, the combination of aluminum oxide abrasive, glass fiber backing, and a robust 22mm bore delivers steady performance, reduced loading, and longer life under typical shop conditions. The 80 grit texture is versatile enough to handle rough stock removal and to leave a smooth, paint-ready surface without a heavy smoothing pass.

Usage guidance

• Mount on a compatible 5" angle grinder with the correct arbor size.
• Keep a light touch and let the disc do the work to minimize heat and glazing.
• Use in overlapping strokes and rotate discs to promote even wear.
• Wear eye protection, gloves, and a dust mask when removing rust, paint, or contaminants.

Care and safety

Inspect discs before each use for cracks or glazing. Store in a dry, cool place to preserve backing integrity and prolong disc life. Follow grinder manufacturer guidelines for safe operation and wheel speed compatibility.

A 50-piece assortment of 5" (125mm) flap discs, each with an 80 grit aluminum oxide abrasive, glass fiber backing, and 22mm bore — ready to accelerate surface preparation, finishing, and weld blending across metal and wood projects.
